because it helps the car when driving
we need rough tyres to increase friction
Beause by this the fiction increase and that's why we don't get slip
rough tires get more traction thus, like sliding.
The treads cut into the surface of vehicle tyres are designed to push aside water on the road surface, and to increase the tyre's grip on the road.
Tyres have treads to give better grip on the road, especially on a wet road.
Tyres have treads to give better grip on the road, especially on a wet road.
the tread is part of the tyre that is supposed to touch the ground
Off-road tyres have deeper treads to help get a better grip on mud and gravel.
The grooves (treads) are there to give better grip (like car tyres) on wet and slippery surfaces.
Less grip on the road surface. Bald tires are also more likely to hydroplane.
On dry, firm roads, pretty much nothing. Treads are there to deal with water and soft surfaces. Modern treads are also designed to help avoid hydroplaning on very wet roadway, without treads a car would very easily hydroplane (completely losing contact with the roadway when there is even just a little water over the roadway, causing the car to 'float' with no traction whatsoever).
I need to know what the codes are on stairs? Treads@risers an hand rails ?for what degree of slope
