Coefficient of friction on raod and a tire varies depending on the condition of the road and tyre
Wet Road: 0.4
Dry Road: 0.7
This is the average coeffecient for these conditions again it can vary

What would happen if the coefficient of friction between the tire and the pavement increased greatly?
Nothing. That's exactly what you want. When your coefficient of friction decreases too far, you need new tires.
Does static friction or rolling friction causes a car tire to turn on the road?
static friction
What is the maximum speed with which a 2500 kg car can round a turn of radius 60 m on a level road if the coefficient of static friction between tire and road is 7?
Really? A coefficient of friction of 7? Unheard of. Probably 0.7 Use F = mv^2 / r where F will be the centripetal force as well as the frictional force, (mu)mg. Solve for v.
What is called the force between the tire and the road?
resistive force (friction)
What factors determine the coefficient of friction?
quality of the Surface is affected to the Coefficient of friction
How does tire tread increase friction between tire and road?
tires are made of rubber and rubber can cause friction
Does static friction or rolling friction causes a car tire to turn on the road?

Why do cars skid more easily on rainy days?
The coefficient of friction between a tire and a wet road is LOWER than the coefficient of friction between a tire and a dry road. It should also be noted that during a dry period, roads are covered by a thin film of dust as well as oil that has leaked from vehicles. At first the rain mixes with these and creates a very slick surface, even further reducing the coefficient of friction. After the rain has washed away some of the dust and oil the roads are slightly less slippery, but still much more so than on a dry road. Note too that standing water can cause a tire to "Hydroplane" at high speed, with "high speed" being a variable that depends on the condition of your tires and the amount of standing water. Hydroplaning is a condition in which the tire is literally lifted off the surface of the road and rides entirely on a film of water.
Does speed affect the friction between a road and a skidding tire?
Speed does not affect the force of friction.
What is rolling friction and what does it do?
In general rolling friction is any friction specifically related to the rolling motion. The friction on the axle to hub bearing, the tire flexing, the tire tread on the surface of the road and so on.
Would the friction between a tire and the road be increased by a wide rather than a narrow tire?
No
What is called the force between the tire and the road?
resistive force (friction)
What makes a tire smoke?
Heat. usually as the result of friction on the road,
Is friction high or low a car tire on a road surface?
high
If your pulling 30 lb tire on a lawn what is the estimated weight youre actually pulling because of friction?
the equation for static friction coefficient is:static friction coefficient = force required to break bond / weight of object (tire)you need the friction coefficient between rubber and grass, say its 0.5, this means the force you have to apply to equal the friction force is:0.5 = x / 30x = 0.5 * 30x = 15 lbs fanything greater than 15 lbs f will break the bond and accelerate the tire.notes :1 / moving friction coefficient is usually less than static friction coefficient, so youve less drag once its moving.2 / friction coefficients are never greater than 1.0actually , some friction coefficients do exceed 1.0 , see google / friction coefficients table
