When it comes to NASCAR racing, the tires on a car play a critical role in how well it accelerates and decelerates as it goes through high-speed turns. And when it comes to tire strategy, NASCAR teams must strike a delicate balance between grip and durability. To do that, they need to know how much each tire and rim weigh.
NASCAR tires and wheels are designed with specific features that influence their overall weight, and there are strict regulations in place to ensure fair competition. However, there are many factors that can affect the weight of a race tire and rim, including their size, materials, and design.
A standard NASCAR Cup Series race tire (dry) weighs 24 lbs, and each wheel weighs 27 lbs. Combined, this makes a total of 51 lbs. That's a lot of weight for a tire carrier and changer to handle during pit stops.
Unlike passenger car tires, which are usually constructed of rubber, NASCAR race tires are typically made of aluminum or steel. This helps them to maintain their strength and integrity during the intense stresses of a race, ensuring that they can withstand high-speed cornering.
Tires also vary in size, allowing teams to optimize them for the conditions of each track. The shape and configuration of a track, as well as its banking, dictates the load that a tire will experience, which in turn informs its construction. For example, a NASCAR tire at Martinsville Speedway will face different loads than a NASCAR tire at Charlotte Motor Speedway.
