Two things racecar tires have to worry about with that your family car tire does not.
1. Heat dissipation and rubber melting rate, racecars want the rubber to melt a little, but not too much.
2. Stiffness, they want very soft rubber, but they don't want it to deform under acceleration, turning and braking so a way to prevent it is increasing the width.
Race car tires are much wider – up to 12 inches wide in the front and 16 inches wide in the rear, whereas the typical passenger car tire is seven to nine inches wide.
The reason they are wide is to increase stiffness so that during acceleration, turns and braking, the amount of rubber touching the road does not decrease too much.
Racecar tires use rubber that is much softer than rubber on cars. It is more like a soft rubber eraser than anything else, and very unlike the hard rubber found in passenger car tires. Since they use very soft rubber it tends to melt during the race, which makes the rubber even stickier than before.
Contrary to intuition, the large width of a racecar tire does not increase the frictional force available to it by itself. If you take your own car and put in tires that are 3 feet wide made of the same kind of rubber, you will not get better grip onto the road.
The reason for this is because as you increase the surface area of the tire, the weight pushing down on a rubber particle decreases. At the macroscopic level, as you increase the surface area touching the ground, the rubber/glue particles break contact with the road and hover over the road instead of touching because there is less force pushing on every rubber particle.
So ultimately the amount of rubber molecules making contact with the road particles are not increased when you use a larger or wider tire on a vehicle with the same weight.
Most race cars have slicks that is a tyre with no tread for maximum grip in the dry. then there is a medium tyre which has a little tread for damp conditions, and there is a tyre called wets which have a lot of tread for raining conditions

How does a burn out ruin tires on race cars?
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.
Where can i get nitrogen for tires?
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.
What gas is used to fill tires for race cars?
Nitrogen
What type of tires do race cars use?
slick tyres are used.
What gas does car tires use?
Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
Gas put in tires of racing cars?
nitrogeon is used to inflate race car tyres due to the consistent tyre pressure throughout different tempertures.
What kind of tires are chosen for race cars?
usually, racing slicks made by Goodyear or Firestone, if its a wet track rain tires.
How does friction helps formula one cars Win a race?
When it comes to tires, it allows the cars to corner, brake and accelerate better.
What type of engine is used in race cars?
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.
What kind of tires are used in racing cars and why?
There are different types of tires depending on what kind of racing they're doing. But pretty much all racing tires tries to be grippier than regular tires. This usually means that they wear out faster, and create more road noise than regular tires, which no one really cares about if can win them the race.
Which gas is pumped into the tires?
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
Why do race cars race?
If race cars didn't race they wouldn't be race cars.
