Classical surface friction is independent of contact surface area yet automobiles still benefit from broader tires because of supplementary forces involved. Because the tire is deformed under loads, it cradles every imperfection in the road surface. The greater the surface area, the greater the number of imperfections that can be cradled therefore increasing the maximum lateral and longitudinal force available. The more force that the tire can exert on the race car, the faster it can turn/accelerate/brake. This ultimately reduces lap times and improves the chance of beating your competitor.
A burn out will ruin tires on race cars by burning up the rubber. The rubber of the tires will get worn from the friction of the pavement causing the tires to tear.
Nitrogen
slick tyres are used.
You will have to be more specific. Race car is too broad a term. There are many different types of race cars using many different engines.
Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
usually, racing slicks made by Goodyear or Firestone, if its a wet track rain tires.
When it comes to tires, it allows the cars to corner, brake and accelerate better.
Air is used to inflated car tyres but cars can be equipped with nitrogeon inflated tyres but this is usually only beneficial to race cars
If race cars didn't race they wouldn't be race cars.
Many industrial supply companies will sell you compressed tanks of dry nitrogen that would be suitable for tires. For normal auto tires, regular air is fine, but nitrogen is often used to inflate the tires of race cars and airplanes.
If they are normal cars there will be 104 tires
Maxxis makes tires for motorcycles, trucks and passenger cars. They have a high rating from users and supply tires to some race car drivers in England.
