Tyre types

Class system

Manufacturers also offer a range of designs to suit different classes of vehicle, driving styles or road conditions

1. 4x4 tyres Multi-purpose rubber is 35 per cent grooved. For off-road tyres, it’s 40 per cent, with wide-set 15mm-deep blocks.		2. Sports tyres Shallow (5-8mm) cuts cover 35 per cent, due to water-pumping channels. Good at high speed in dry and in rain.
3. Winter tyres Have similar groove area to sports tread, but more blocks, up to 10mm deep. Tiny strips give extra grip on snow and ice.		4. Standard tyres Grooves 6-9mm deep cover 30 per cent of the tread. Suited to dry or wet roads, with some ability on snow.
