Tyre Tread Depths
Are your tyres legal? When should you change them?
Always ensure your tyres conform to the U.K minimum legal tread depth requirement of 1.6mm. this means your tyres should have at least 1.6mm of tread left across the central three quarters of the tyre tread breadth and around the entire circumference of the tyre.
Various types of tread depth checking devices can be purchased from car product specialists. these can be dipped into the tyre tread to measure the depth in millimetres.
In addition, most car tyres now have tread wear indicators set into the tread grooves, which show when when the tyre is worn to 1.6mm of remaining tread. When these indicators become level with the tread surface your tyres should be changed immediately.
Maintaining the correct tyre pressure is an important factor in both the safety and longevity of tyres. Too little or too much air could adversely affect the vehicle handling and the tyre's performance and durability.
Additionally keeping your tyres at the correct pressure and using energy efficient tyres reduces your engine's workload. This means you'll save fuel and reduce C02 emissions too!
Pressures should be checked using an accurate gauge, available at most petrol stations or from car product specialists.
Make sure of the correct tyre pressures by referring to the vehicle manufacturer's advice, to be found in the handbook, on the door pillar or on the fuel filler cap.
Check tyre pressures monthly and before any long trip. The tyres should be checked when cold, as they heat up as you drive causing a slight increase in pressure. Do not forget to check the spare tyre.
If you intend towing with the vehicle, e.g. a trailer or caravan, always consultant the vehicle handbook or trailer, caravan or tyre manufacturer for suggestions as increased pressures may be required.
