Question

groves of on tyre dash
friction between the tyre and Road​

Answer 1

Answer:

Tyres have grooves to increase the friction between them and road. This enables the vehicle to make firm grip on road and prevent sliping. The grooves in the rubber are designed to allow water to be expelled from beneath the tire and prevent hydroplaning.

Explanation:

Answer 2

Answer:

It's the grip of the tyre on the road and is caused by the friction between the rubber and asphalt. The rougher the two surfaces, the higher the friction and the better the traction. ... The grooves (or “voids”) on tyres are there to provide a channel for the water

OR

Grooves decreases contact area between tyre and road at the contact patch. Tyre friction is directly proportional to contact area
