Tyre Maintenance Checklist for Scottish Drivers

Your Monthly Tyre Check in 5 Minutes

Scottish roads, rain, and temperature swings are hard on tyres. A 5-minute monthly check prevents blowouts, improves fuel economy, and keeps you legal. Here's what to check.

Quick answer: Check pressure, tread depth, and visual condition once a month and before any long journey. It takes 5 minutes and could save your life.

1. Tyre Pressure

Why It Matters

Underinflated tyres are the single biggest cause of blowouts. They also:

• Increase fuel consumption by up to 3%
• Wear unevenly (edges wear faster)
• Handle poorly in wet conditions
• Increase braking distance

How to Check

1. Find your vehicle's recommended pressure — it's on a sticker inside the driver's door or in the owner's manual
2. Check when the tyres are cold (not driven for 2+ hours)
3. Use a digital gauge (more accurate than pencil-type)
4. Check all four tyres and the spare
5. Adjust to the correct PSI at a petrol station air pump

Scottish-Specific Tip

Temperature drops of 10°C can reduce tyre pressure by 1-2 PSI. In Scotland, where temperatures can swing 15°C between day and night in spring/autumn, check more frequently during seasonal changes.

2. Tread Depth

Legal Requirements

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

• 1.6mm is the bare legal minimum — braking performance is significantly worse
• 3mm is the safety threshold — we recommend replacing at this point
• Below 3mm in wet conditions increases stopping distance by up to 44%

How to Check

The 20p test:

1. Insert a 20p coin into the main tread grooves
2. If you can see the outer band of the coin, your tread is below 3mm
3. Check at three points across the tyre width
4. Check at several points around the circumference

Penalty for Illegal Tyres

• £2,500 fine per tyre
• 3 penalty points per tyre
• 4 illegal tyres = 12 points = automatic ban

3. Visual Inspection

Look for these warning signs every time you walk to your car:

What to Look For	What It Means	Action
Bulge on sidewall	Internal structural damage	Replace immediately — tyre could blow
Cracks in rubber	Age or UV degradation	Replace soon, especially if deep
Embedded objects	Nail, screw, glass	May be repairable — call for assessment
Uneven wear (inner edge)	Alignment issue	Get alignment checked + consider new tyres
Uneven wear (centre)	Over-inflation	Adjust pressure and monitor
Uneven wear (both edges)	Under-inflation	Adjust pressure and monitor
Flat spots	Brake lockup or sitting too long	Usually temporary; replace if persistent

4. Seasonal Considerations for Scotland

Winter (November–March)

• Check pressure more frequently (cold reduces PSI)
• Consider winter tyres if you regularly drive in Highlands or rural areas
• All-season tyres are a good compromise for Glasgow/Edinburgh city driving
• Watch for pothole damage after freeze-thaw cycles

Summer (April–October)

• Hot tarmac increases tyre temperature — don't over-inflate
• Check for cracking if tyres are over 3 years old
• UV exposure degrades rubber — inspect sidewalls

Year-Round Scotland Issues

• Potholes — Glasgow and Edinburgh roads are notoriously potholed. After any impact, check for bulges
• Standing water — worn tyres aquaplane easily on Scotland's wet roads
• Debris — country roads often have sharp stones, hedge cuttings, and farm equipment remnants

5. When to Replace Your Tyres

Replace immediately if:

• Tread depth is at or below 1.6mm anywhere
• There's a bulge or blister on the sidewall
• You can see cords or metal through the rubber
• The tyre is over 10 years old (check the DOT date code)

Replace soon if:

• Tread is at 3mm or below
• Cracking is visible on the sidewall
• The tyre is over 5 years old regardless of tread
• You notice vibration or pulling when driving

Frequently Asked Questions

How often should I check my tyres?

Monthly and before any journey over 100 miles. It takes 5 minutes.

Where can I get my tyres checked in Glasgow?

Tyre Rescue offers free tyre condition assessments with any mobile fitting appointment. Call 0141 266 0690 to book.

Do I need winter tyres in Glasgow?

For city driving, all-season tyres are usually sufficient. If you regularly drive to the Highlands or rural areas in winter, dedicated winter tyres provide significantly better grip below 7°C.

How do I find my tyre size?

Look on the tyre sidewall — you'll see markings like 205/55R16 91V. This tells us everything we need to match the correct replacement.
