it affects it greatly. For racing, the best tyres to use are called "slicks". This means that there is no tread on the tyre. The more tyre you have, the more grip you have. Road cars, however, need to have tread because the tread helps to grip in gravel and water. The tyre for normal road use is also designed so that it can get rid of the water that gets caught in the tread. As well, inflation of the tyre affects the surface area if under-inflated; the tread area collapses, even if you don't see much change with the naked eye. It makes a "mushy" less effective grip. If over-inflated, the tread has more pressure exerted on it from within, which widens the tread and lessens the grip on road surfaces.

Why do you need tread on tires?

The "tread" is the part of the tire that is supposed to touch the ground. A tire with no tread would be a tire that is not supposed to touch the ground. You may be wondering why tires have a pattern of grooves (a.k.a., voids) in the tread. They're for bad weather. The grooves allow rain, and (if they're wider) mud and snow to squelch out from under the tire so that the tread can come into contact with something solid on which to get a grip.

How do you reduce tire noise?

Tire noise can be caused by the tread pattern used on your tires. Off road tires have a deep tread pattern to give better grip on soft surfaces. Change to a road tire. Road noise can also be caused by worn suspension components, especially the rubber bushes. Check that yours are not worn. They go soggy or split with age.
