Do race car tires have tread?
Regular tires have tread, unlike race car tires which do not have any tread at all. Race cars use tires without tread because smooth tires provide better traction in dry conditions. If the ground is wet, however, drivers will suddenly find themselves needing the grooved tread that siphons water away from the tires.
Why do drag racing tires have no tread?
Tread is required to move rain water out of the way so the tire can grip on wet roads. Road tires, therefore, need tread to be able to drive safely in the rain. “Slicks” – tires without a tread – are used by racing cars when it’s dry, because they grip better than they would do if they had a tread.
Why do race car tires wear out so fast?
