TREAD
What It Is
The tread is the part of the tyre that contacts the road and is designed to improve grip in the wet but its effectiveness gradually reduces as it wears. The UK's minimum legal tread depth is 1.6mm within the central three-quarters of the breadth of tread and around the entire outer circumference.
Why It Is Important
Without adequate tread depth your tyres may not perform properly in wet conditions, reducing your safety on the road. Your braking, steering and accelerating are all affected by your tyre tread. If your tread depth is below 1.6mm you can be fined up to £2,500 and three penalty points for each illegal tyre.
How To Check
Check the depth of the main tread grooves in several places across and around the tyre using a tread depth gauge. If you dont have a gauge, use a 20p coin as a guide. If the outer rim of the coin is visible when it is inserted into the groove, then your tread depth may be below the legal limit.
