UK Tyre Law: What Every Driver Must Know
Driving on illegal tyres in the UK is a serious offence. UK tyre safety law is enforced through regular police and DVSA checks, and the penalties are significant. Understanding your legal obligations protects you, your passengers and other road users.
Legal Tread Depth Requirements
The UK's minimum legal tread depth for cars and light vans is 1.6mm across the central three-quarters of the tread width, around the entire circumference. Motorcycles above 50cc also require 1mm minimum tread depth. Driving on tyres below these limits risks:
- A fine of up to £2,500 per illegal tyre
- 3 penalty points per illegal tyre (up to 12 points for a full set)
- Immediate prohibition of the vehicle by police or DVSA enforcement officers
Tyre Condition Requirements
Beyond tread depth, UK law requires tyres to be free from:
- Any cut or tear more than 25mm or 10% of the tyre section width long (whichever is greater) that exposes cords
- Lumps, bulges or tears caused by separation or partial failure
- Any ply or cord exposed
Tyre Type and Mixing
UK law requires that tyres on the same axle must be the same type of construction — you cannot legally mix radial and crossply tyres on the same axle. It is also a legal requirement that tyres are the correct size and type for your vehicle.
Insurance Implications
Driving on illegal tyres could also invalidate your motor insurance. In the event of an accident, your insurer may use illegal tyre condition as grounds to reject your claim. Our mobile tyre fitting service ensures your tyres are always road-legal, correctly fitted and properly balanced.
