Top tyre tips
Check your pressures
You'll find the recommended pressures inside the drivers' manual. Check the pressure when the tyre is cold, as even a short journey will warm up tyres and raise the pressure.
Under-inflation can cause tyre damage, uneven wear, and an increase in fuel consumption.
Over inflated tyres give a less comfortable ride and wear out in the centre of the tread.
Check the pressure in the spare tyre to ensure it's ready in an emergency.
Check your treads
Worn tyres mean less grip.
Abnormal or uneven wear can often be an indication of a mechanical defect on the vehicle. In these circumstances the mechanical parts (steering, wheel alignment, brakes) should be check immediately.
Check for damage
Look for cuts, cracks and bulges or any other evidence of damage from violent impact or kerbing. Damaged tyres may be illegal and can be dangerous
Know the tyre law
The legal minimum tread depth for car tyres in the United Kingdom and the European Community is 1.6mm throughout a continuous band comprising the central three quarters of the breadth of tread and round the entire outer circumference of the tyre.
Most car type tyres have tread wear indicators, usually at least six small ribs across the bottom of the main tread grooves, and when the tread surface becomes level with these ribs the tyre is at the legal limit and must be replaced.
One of the features of tyre tread pattern designs is to give good grip in wet conditions. Generally speaking available grip reduces as the tyre wears or as the road surface water depth increases and you should reduce speed in such conditions.
The 1.6mm minimum legal limit applies to:
Cars and passenger vehicles with up to 8 seated passengers - not including the driver
Motor vehicles and light trailers (including caravans) up to 3500 kg gross vehicle weight
