How does tire pressure influence vehicle handling on a raceway?

Tire pressure plays a crucial role in vehicle handling, particularly on raceways where performance is paramount. Lower tire pressure can enhance grip because it allows the tire to have a larger contact patch with the road surface. A larger contact area increases traction, which is beneficial during high-speed cornering or braking. However, this setup has its limits; if the tire pressure is too low, it can lead to overheating. This is due to excessive sidewall flex and increased rolling resistance, which can ultimately degrade tire performance and safety.

On the other hand, higher tire pressure can create a smaller contact patch, which generally reduces grip because the tire may not conform as well to the track surface irregularities. Although higher tire pressure can minimize tire wear and enhance stability at high speeds, it compromises grip, especially during cornering. Thus, finding the optimal tire pressure is essential for maintaining the balance between grip and performance on the raceway.

This understanding clarifies why the influence of tire pressure on vehicle handling cannot be overlooked, making the selected answer the most accurate reflection of its impact on racing performance.
