How Often Should You Change Your Tyres? UK Guidelines Explained

Introduction

Your tyres are your vehicle’s only contact with the road — and keeping them in good condition is vital for your safety, fuel efficiency, and legal compliance. But how do you know when it’s time to replace them?

In this guide from Drift Bridge Group, we’ll explain how often you should change your tyres, the UK legal tread depth requirements, and the warning signs that it’s time for new rubber.

What Is the Legal Tyre Tread Depth in the UK?

In the UK, the legal minimum tread depth for passenger vehicles is 1.6mm across the central three-quarters of the tyre and around the entire circumference.

However, many motoring experts — including the AA and RAC — recommend changing tyres when tread reaches 3mm, as braking distances significantly increase below this point, especially in wet conditions.

How Often Should You Change Your Tyres?

There’s no one-size-fits-all answer, as tyre lifespan depends on several factors:

On average, you should consider replacing tyres every:

• 20,000 to 30,000 miles for front tyres (on front-wheel-drive cars)
• 40,000 to 50,000 miles for rear tyres
• 5 to 6 years, even if tread depth is still legal — due to ageing rubber

But more frequent changes may be needed if you:

• Drive long distances regularly
• Drive on rough or poorly maintained roads
• Have aggressive driving or braking habits

Signs Your Tyres Need Replacing

Aside from low tread, here are key warning signs your tyres may need replacing:

• Cracks or splits in the sidewall
• Bulges or blisters on the tyre surface
• Uneven wear across the tread (could indicate alignment issues)
• Vibration while driving, especially at higher speeds
• Longer braking distances or poor grip in wet weather

If you notice any of these, it's best to book a tyre check promptly.

How to Check Your Tyre Tread at Home

Use a 20p coin to check tread depth:

• Insert the coin into the tyre’s main grooves.
• If you can see the outer band of the coin, your tread is below 3mm and replacement is advised.

This simple test takes just seconds and can help you stay safe and legal.

Should You Replace All Four Tyres at Once?

It's usually best to replace tyres in pairs (front or rear) to maintain balanced handling and braking.

You may need to replace all four if:

• They’re all worn close to the legal limit
• You drive a four-wheel-drive or all-wheel-drive vehicle (to avoid drivetrain damage)
• You’re switching to seasonal tyres (e.g. winter or all-season)

How to Make Your Tyres Last Longer

To extend tyre life and get the most from your investment:

• Check tyre pressure monthly and keep it at the recommended level
• Rotate tyres every 6,000–8,000 miles
• Get your wheels aligned and balanced regularly
• Avoid harsh braking or aggressive cornering
• Have your suspension inspected if wear is uneven
