NASCAR cars use specialized tires that are designed to withstand the high speeds and extreme forces encountered during races. These tires are produced by two main manufacturers: Goodyear and Firestone.
The tires used in NASCAR are typically slick, meaning that they have no tread pattern. They are also designed to have a very soft compound, which helps them grip the track surface more effectively. This soft compound allows the tires to generate more friction with the track, which helps the cars to corner more quickly and accelerate faster.
NASCAR tires are also wider than normal car tires, which provides more contact area with the track surface. This added surface area increases the amount of grip the tires can generate, helping the car to maintain control at high speeds and through tight turns.
Overall, the tires used on NASCAR cars are highly specialized and optimized for the demands of oval track racing. They are not suitable for use on normal roads, as they lack the tread pattern required for safe operation in wet or slippery conditions.
