Tyre Safety Checklist Every Glasgow Driver Should Follow

By the team at 247 Mobile Tyre Service Glasgow's trusted 24/7 mobile tyre fitting specialists serving all of Scotland.

Most Glasgow drivers think about their tyres twice a year when something goes wrong, and when the MOT is coming up.

That gap in between is where problems grow quietly.

A slow pressure loss. A sidewall crack that develops after a hard pothole hit. Tread wearing unevenly because the alignment is slightly off. None of these feel urgent until they suddenly are usually at the worst possible time, on the worst possible road.

This is the exact checklist we recommend to every Glasgow driver we meet. It takes five minutes a month. It costs nothing. And it catches the vast majority of tyre problems before they turn into emergencies, MOT failures, or accidents.

Bookmark this page. Work through it once. Then make it a habit.

The 5-Minute Monthly Visual Tyre Safety Check

The short answer: once a month, do a full walk-around of all four tyres. It takes five minutes and catches most problems early.

Here's how to do it properly.

Step-by-Step Walk-Around Inspection

Park on a flat, well-lit surface. Work around the car in the same order every time front left, rear left, rear right, front right so you never skip one. For each tyre:

Crouch down and look at the full tyre surface — tread area, sidewalls, and the inner shoulder where the tyre meets the rim
Run your hand across the tread — uneven wear (ridges, bald patches on one side) is easier to feel than see
Look at the sidewall from the side — any bulges, bubbles, or distortions are an immediate red flag
Check for embedded objects — nails, screws, and sharp stones often sit flush with the tread and hold pressure for weeks before causing a slow puncture
Check tyre-to-rim junction — look for cracks, rust, or separation at the bead area

Do this in natural light if possible. A torch helps for checking inner shoulders and lower sidewall areas.

Tread Depth Check The 20p Test

UK legal minimum tread depth: 1.6mm across the central three-quarters of the tyre.

Our recommendation for Scottish driving: don't let it drop below 3mm. On wet roads which describes most of Scotland for most of the year tread below 3mm significantly increases stopping distances and aquaplaning risk.

The 20p coin test: Insert a 20p coin into the main tread groove. If the outer band of the coin (the raised rim around the edge) is visible above the tread, you're below 3mm. Time to take action.

For a more accurate reading, a tyre tread depth gauge costs around £5–£8 and measures to 0.1mm. Worth having in the glovebox. Check at multiple points across the tyre width and around the circumference wear is often uneven.

Tread Depth	Status	Action
Below 1.6mm	Illegal	Replace immediately
1.6mm – 2mm	Critical	Replace as soon as possible
2mm – 3mm	Low	Plan replacement within weeks
3mm – 4mm	Getting low	Monitor weekly
4mm+	Acceptable	Monthly check sufficient

Sidewall and General Damage Inspection

The sidewall is structural. It's what keeps the tyre's shape and supports the load. Damage here is serious and unlike tread punctures, sidewall damage is never repairable.

Look for:

Bulges or bubbles — these indicate internal structural failure, usually from a hard pothole impact. A bulging sidewall can fail without warning. Stop driving and call us.
Cuts and gashes — surface cuts from kerbs may be cosmetic; deeper cuts that reach the cords are dangerous
Cracking or crazing — fine networks of cracks across the sidewall indicate rubber degradation from age. Common in tyres over 6–7 years old, even if tread looks fine
Scuffing from kerb strikes — often cosmetic, but worth checking the inner structure hasn't been compromised

If you spot a bulge, don't drive on it further than necessary to reach a safe stopping point. Call 07955 533000 — this is an emergency fix, not a "next week" job.

Tyre Pressure Check Cold Tyres Only

Tyre pressure is the most impactful thing you can check yourself and the most commonly neglected.

Check pressure when tyres are cold before driving, or after the car has sat for at least three hours. Pressure rises as the tyre heats up during driving, so a hot reading is always higher than the true cold pressure.

Find the correct PSI for your vehicle in:

The driver's door jamb sticker (most vehicles have this)
The fuel cap flap
Your vehicle handbook

Note that front and rear pressures are often different. Many cars also recommend higher pressure when fully loaded check the handbook for the loaded specification if you're doing a long trip with passengers and luggage.

Common mistake: Using the pressure printed on the tyre sidewall. That's the maximum pressure the tyre can hold not the pressure your vehicle requires. Always use your vehicle handbook figure.

Check all four tyres and the spare if you have one. A spare with no pressure is useless when you need it.

Valve Caps and Tyre Age

Valve caps small but important. They keep dirt and moisture out of the valve, which prevents slow leaks. If a valve cap is missing, replace it. They cost pennies.

Tyre age (DOT code) every tyre has a DOT code moulded into the sidewall. The last four digits show the week and year of manufacture. A tyre marked 1821 was made in week 18 of 2021.

Rubber degrades over time regardless of mileage. At around 6 years, performance begins to decline grip, flexibility, and structural integrity all reduce. At 10 years, most manufacturers recommend replacement regardless of tread depth.

If you've owned your car for several years and never thought about tyre age, check the DOT codes this month. If any tyre is approaching or past the six-year mark, book a professional inspection.

Weekly Quick Checks for Glasgow Commuters

Glasgow's roads are particularly demanding. Potholes in the Southside back streets. Rough surfaces around the East End delivery routes. The constant expansion-joint hits on motorway bridges over the M8 and M74. If you're driving daily in the city, a weekly check takes 60 seconds and catches the things that change between monthly inspections.

Tyre Pressure Weekly in Winter

Tyre pressure drops approximately 1 PSI for every 10°C fall in temperature. In Scotland, that matters from October through to April.

A tyre that was correctly inflated in September may be 4–5 PSI low by December without a single puncture. Check pressure at least twice during the winter months and any time there's been a significant temperature change overnight.

Visual Damage After Potholes or Kerb Strikes

After hitting anything significant a pothole, a raised drain cover, a kerb do a quick visual check before continuing your journey.

Look specifically at the sidewall of the tyre that took the impact. A bulge that wasn't there before the hit means internal structural damage. Even without a visible bulge, a hard pothole impact can cause internal cord damage that isn't immediately visible. If the car handles differently after an impact pulling, vibrating, steering feeling off pull over and check.

Unusual Noises and Vibrations

Vibration through the steering wheel at specific speeds usually means a balancing issue often developing after a pothole impact dislodges a wheel weight.

A thumping or rhythmic noise at low speeds can indicate a flat spot on a tyre (from emergency braking or from a run-flat that's been driven on excessively) or a developing structural failure.

A hissing sound when you're stationary is worth investigating it might be a slow puncture losing air faster than usual.

None of these should be ignored for "a few more days." They indicate something worth looking at.

TPMS Warning Lights

If your Tyre Pressure Monitoring System warning light comes on, don't reset it without finding out why.

Pressure loss is a symptom the light is telling you a tyre has dropped significantly below its target pressure. Find out which tyre, find out why, and address it. Resetting the light doesn't fix the underlying issue.

Some TPMS systems indicate which specific tyre has dropped pressure (direct TPMS). Others only tell you that one of the four is low (indirect TPMS). If you're not sure which system your car uses, your handbook will clarify.

Seasonal Tyre Safety Checklist

Scottish seasons make specific demands on tyres. Working through a seasonal checklist twice a year spring and autumn sets you up for the conditions ahead.

Spring / Summer Checklist (April–September)

After winter:

[ ] Inspect all four tyres for winter damage — sidewall cracks, deeper tread wear from cold-weather use, impact damage from winter potholes
[ ] Check tread depth — winter driving is harder on tyres
[ ] Check and correct pressure — temperatures rising means pressure may be running slightly high now
[ ] Inspect rims for corrosion or damage from salt and grit
[ ] Check DOT codes — if tyres are approaching 6 years, plan replacement before next winter

Before summer long trips:

[ ] Check pressure against the loaded specification in your handbook if carrying extra passengers or luggage
[ ] Check tread at multiple points — summer motorway driving at sustained speeds generates heat; good tread depth matters
[ ] Visually inspect sidewalls — UV exposure over summer can accelerate surface cracking on older tyres

Autumn / Winter Checklist (October–March)

This is the critical one for Scottish drivers.

Before winter:

[ ] Check tread depth — minimum 3mm recommended for winter driving in Scotland. Below 3mm in cold, wet conditions is a meaningful safety risk
[ ] Check sidewall condition — cold weather makes rubber less flexible and surface cracks more significant
[ ] Assess tyre age — rubber compounds perform increasingly poorly in cold as the tyre ages. If you have 7+ year old tyres, get them professionally assessed before winter
[ ] Consider all-season or winter tyres if you drive regularly when temperatures consistently drop below 7°C
[ ] Check spare tyre pressure — a flat spare in January is a bad situation to be in

Monthly through winter:

[ ] Pressure check — cold weather drops PSI, check more frequently than summer
[ ] Post-pothole visual — winter roads are rougher and potholes hit harder in frozen conditions
[ ] TPMS monitoring — if the light comes on, act on it the same day

When to Switch Tyres

For drivers running summer and winter tyre sets:

Switch to winter tyres when overnight temperatures consistently drop to or below 7°C typically mid to late October in Scotland.

Switch back to summer tyres when overnight temperatures consistently stay above 7°C typically April in Central Belt, later in Highland areas.

All-season tyres (with the 3PMSF snowflake marking) are a practical alternative for drivers who don't want to manage two sets. For Scottish conditions, they're a genuinely sound choice for most drivers.

Advanced Professional-Level Checks What We Do On-Site

A self-check is valuable — but there are things that require tools and training to assess properly. Here's what a professional mobile inspection from 247 Mobile Tyre Service covers that you can't replicate in your driveway.

Full 4-Tyre Professional Inspection

Calibrated tread depth measurement at multiple points across and around each tyre not just the central groove
Inflation to the exact vehicle-specific PSI using a calibrated gauge, not a petrol station estimate
Sidewall condition assessment including inner sidewall the part you can't see without lifting the vehicle
DOT code reading and age assessment with professional guidance on whether age is a concern for your specific tyres
Rim and bead area inspection where the tyre meets the wheel, looking for damage, corrosion, or poor seal

Wheel Alignment Check

Misalignment causes uneven tyre wear that's often subtle at first a faster wear rate on the inner or outer shoulder and becomes obvious only when significant damage has already occurred.

After any hard pothole impact, alignment should be checked. For Glasgow commuters covering high annual mileage, an alignment check every 15,000 miles is sensible maintenance, not excessive caution.

We flag alignment concerns during mobile inspections and can refer for correction or advise on urgency.

Suspension and Brake Interaction

Worn shock absorbers increase tyre wear and reduce the contact patch between tyre and road directly affecting braking and handling. We note visible suspension issues during professional inspections and advise accordingly.

Uneven wear patterns often tell a story about the vehicle's mechanical condition as much as about the tyre itself.

Run-Flat and Commercial Vehicle Checks

Run-flat tyres require specific assessment tools standard visual checks don't reveal internal damage accurately. If your vehicle uses run-flat tyres and you've driven on a deflated or near-deflated tyre, a professional inspection is essential before continuing to rely on them.

Commercial vehicles require checks for load index compliance on every axle, correct torque on all wheel nuts, and condition of tyres under the kind of stress that passenger cars rarely experience.

Locking Wheel Nut Condition

If your vehicle has locking wheel nuts, check that the key is present and in usable condition. A worn or damaged locking nut key means the wheel can't be removed for a tyre change by you or by us without specialist removal tools.

We carry removal equipment for emergencies, but identifying a damaged key before you need it is obviously better.

Red Flag Issues Act Immediately

Some findings on a tyre check are not "monitor and review" situations. They require immediate action.

Critical Stop Driving Now

Sidewall bulge or bubble — internal structural failure. The tyre can fail without further warning. Do not continue driving.
Tread below 1.6mm — illegal and genuinely dangerous in wet conditions. Replace before the next drive.
Deep cuts reaching the tyre cords — structural integrity is compromised. The tyre needs immediate assessment and almost certainly replacement.
Severe cracking across the sidewall — rubber degradation has reached the point where the tyre's structure is unreliable.

Call 07955 533000 for any of these. We'll come to you.

High Priority Address This Week

Tread between 1.6mm and 3mm — legal but below our recommended safety threshold for Scottish roads. Book replacement.
Noticeably uneven wear — indicates an alignment, balancing, or suspension issue. Driving on continues to damage the tyre and underlying problem.
Persistent TPMS warning — pressure loss that keeps recurring after inflation means a puncture, valve failure, or rim issue. Needs diagnosis.
Vibration at speed — balancing issue or structural tyre damage. Don't leave it for weeks.
Tyre age 6+ years — arrange a professional assessment. Age-related degradation isn't always visible.

Tyre Safety for Different Drivers

The same checklist applies to everyone but the frequency and focus areas differ by driver profile.

Family and Daily Commuters

Your tyres carry your family. The M8 school run, the weekend trip to Loch Lomond, the late return from Edinburgh these are the journeys where tyre failure has the most serious consequences.

Monthly checks as standard. Pre-long-journey check as a habit. Professional inspection every six months.

For families regularly loading the car with passengers and luggage, always check pressure against the vehicle's loaded specification before the trip it's usually higher than the standard figure.

High-Mileage Drivers

If you're covering 20,000+ miles annually reps, contractors, regular long-distance commuters tyre wear happens faster and issues develop more quickly. Monthly checks aren't enough.

Every two weeks is a more appropriate interval. Professional inspection every four to five months rather than six. Pay particular attention to tread depth at high mileage, it drops quickly.

Van and Commercial Fleet Operators

Load index compliance matters here more than in any other category. Carry what your tyres are rated for. Check tread depth and pressure before every working week, not just once a month.

For fleet managers overseeing multiple vehicles, a scheduled mobile inspection arrangement with 247 Mobile Tyre Service means consistent professional checks across your whole fleet without pulling vehicles from service. We provide written records that support your compliance obligations.

New and Young Drivers

If you've recently passed your test, there's a reasonable chance nobody has ever shown you how to check your tyres properly. That's not unusual — it's not part of the test, despite being one of the most important maintenance tasks a driver can do.

Work through this checklist with a parent, friend, or instructor once. After that, it takes five minutes and you'll know exactly what you're looking for. The legal penalties for illegal tyres — up to £2,500 fine and 3 penalty points per tyre fall on the driver, not the vehicle owner.

The Mobile Tyre Safety Inspection Advantage

Self-checks are valuable. Professional checks are better.

There are parts of your tyre you physically can't inspect without lifting the vehicle. There are measurements you can't make accurately without calibrated tools. And there are developing problems alignment issues, age-related degradation, early sidewall damage that require trained eyes to identify reliably.

A professional mobile tyre inspection from 247 Mobile Tyre Service comes to you. Your driveway. Your workplace car park. Anywhere across Glasgow and Scotland.

What a full professional mobile safety check includes:

Calibrated tread depth measurement across all four tyres
Pressure check and correction to vehicle-specific PSI
Full sidewall and bead area inspection including inner face
DOT code reading and tyre age assessment
Rim condition and tyre-to-rim seal check
TPMS system check where relevant
Written report of findings with prioritised recommendations

How often should you book?

Every 6 months as standard ideally spring and autumn
Before any long Highland or motorway trip
After any significant pothole or kerb impact
Any time you notice a change in handling, noise, or vibration
4–6 weeks before your MOT

The cost of a professional inspection is far less than the cost of catching a problem too late. For a busy Glasgow driver, the convenience of a technician coming to your home or office removes the last barrier.

Real Results How This Checklist Helps Glasgow Drivers

The prevented blowout in the West End A driver doing a routine monthly check following this guide found a nail embedded so squarely in the rear tread that almost no air was escaping a slow puncture that would have deflated gradually over the following week. Repair cost: £25. Avoided: a blowout on the M8 during rush hour.

The MOT pass after a near-failure A driver in Bearsden checked his tread depth six weeks before his MOT using the 20p coin test something he'd never done before. Two front tyres were below 3mm, one approaching the legal limit. He called us, we fitted replacements at his home the same week, and his MOT passed without issue. He told us the garage had failed his previous MOT on tyres he hadn't checked.

The age catch that prevented a highway incident During a routine professional mobile inspection in the South Side, we flagged a tyre with a DOT code indicating it was manufactured nine years earlier. The tread looked fine around 4mm remaining. But the sidewall showed the fine crazing pattern that indicates age-related rubber degradation. The driver had no idea. We replaced all four tyres (two were from the same manufacturing run). The remaining two were also past the seven-year mark.

The alignment problem caught early A nurse working shifts at a Glasgow hospital noticed her front-left tyre was wearing faster than the others during a monthly walk-around a ridge on the inner shoulder that she could feel but barely see. We inspected during a home visit and confirmed a significant alignment issue after a pothole impact she'd forgotten about. Alignment correction plus one new tyre: around £120. Alternative: premature wear on all four tyres and a bill several times higher.

Digital Reminder Tips

Set a recurring monthly reminder on your phone first of the month works well, or tie it to something you already do (first Sunday of the month, the day you get paid). Label it clearly: "Tyre check 5 mins."

For winter months (October–March), add a second reminder mid-month for a pressure check only. It takes 90 seconds per tyre and catches the pressure drop that cold weather causes.

Combining With Other Maintenance

Align your tyre checks with other natural maintenance points:

Every service — ask the garage to check alignment and tread depth as part of the service inspection
Before every MOT — professional mobile tyre check 4–6 weeks before the test, leaving time for any replacements
After any winter — full four-tyre inspection each April as the season changes

Building the Habit

The drivers who stay safest aren't the ones who know the most about tyres. They're the ones who check consistently, even when nothing looks wrong.

Five minutes. Once a month. Same order every time. It becomes automatic within two or three months — and it's one of the most effective things you can do for your safety and your wallet.

Conclusion: Five Minutes That Could Save Your Life

Tyre problems don't announce themselves in advance. They build quietly pressure dropping, tread thinning, rubber ageing until something gives way at the worst possible moment.

This checklist breaks that pattern. Monthly checks catch slow changes before they become dangerous. Seasonal checks prepare you for what Scottish roads are about to throw at you. And a professional inspection twice a year gives you the confidence that comes from knowing trained eyes have assessed every tyre properly.

The M8 at rush hour. The A82 through Glencoe in the dark. The school run on a wet Southside morning. These are the journeys that depend on four well-maintained tyres doing their job.

Follow the checklist. Make it a habit. And when you want professional confirmation that everything is genuinely safe call us.

Frequently Asked Questions

How often should I check my tyres in Glasgow? Monthly for a full visual check and pressure check. Weekly during winter months for a quick pressure check cold Scottish temperatures drop PSI noticeably and monthly isn't frequent enough between October and March. After any significant pothole or kerb impact, check immediately.

What is the legal minimum tyre tread depth in Scotland? 1.6mm across the central three-quarters of the tyre, around the full circumference. The penalty for driving on illegal tyres is up to £2,500 and 3 penalty points per tyre. We recommend maintaining 3mm minimum for Scottish driving conditions particularly in autumn and winter.

How do I check my tyre tread depth without a gauge? Use the 20p coin test insert a 20p into the main tread groove. If the outer raised band of the coin is visible above the tread, you're below 3mm. For accuracy, a tread depth gauge costs around £5–£8 and gives a precise reading to 0.1mm.

What does a bulge in my tyre sidewall mean? It means internal structural failure the tyre's reinforcing cords have broken, usually from a hard pothole or kerb impact. A bulging sidewall can fail without warning. Do not drive on it beyond what's needed to reach a safe stopping point. Call 07955 533000 immediately this is not a "later this week" situation.

How do I find the correct tyre pressure for my car? Check the sticker inside the driver's door jamb, the fuel cap flap, or your vehicle handbook. Don't use the maximum pressure printed on the tyre sidewall that's the tyre's maximum capacity, not your vehicle's recommended pressure. Front and rear pressures are often different.

How old is too old for a tyre? Rubber compounds degrade over time regardless of mileage. From around 6 years, performance begins to decline. Most manufacturers recommend replacement at 10 years maximum. Check the last four digits of the DOT code on the sidewall they show the week and year of manufacture (e.g., 1821 = week 18 of 2021).

Can I check my own tyres or do I need a professional? Both. Your monthly self-check catches most problems pressure loss, visible damage, tread depth, sidewall issues. A professional inspection twice a year covers what you can't check yourself: inner sidewall condition, calibrated tread measurement across the full tyre, rim and bead seal, and age-related assessment. Together they give you complete coverage.
