how does friction help car tyres?
Friction is useful when I want to stand up (trying to stand on a frictionless surface is difficult, and dangerous), but more friction is a problem when I am ice skating. Friction with my car tires is useful when I am driving on a road (especially if I want to stay on the road around a curve, or want to speed up or slow down), but more friction on the moving parts of the engine is a problem.
Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.
Friction is useful when you are trying to stop a car, but not useful in the pistons of a car's engine (It makes them less efficient).
It's useful
The friction is useful on a bike when you push it.
Enables cars to move, rather than just spin tyres and go nowhere.
the friction is between the tyres of cycle and the road surface. Without friction movement is impossible.

Friction is desirable on your tyres and brakes. Tyres need to grip the road, to push the car forward, stop and go round corners. Brakes need friction to stop the wheels turning.
Friction is useful in various ways, such as enabling us to walk and grip objects. It is crucial for vehicles to move on roads and for machines to operate effectively. Friction also helps in slowing down moving objects and preventing slipping or sliding.
Flabby tyres produce more friction with the road.Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)
because of good friction.....
Friction is useful in brakes because it converts kinetic energy (movement) into thermal energy (heat), which helps slow or stop a vehicle by creating resistance. When the brake pads press against the rotating brake disc or drum, the resulting friction generates heat that dissipates energy and slows down the vehicle.
forward friction on the tyres from the road..
to reduce friction tyres are made circular
we need rough tyres to increase friction
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
