How Do Flat Tires Influence Cornering and Stability During a Race?

Flat tires negatively impact cornering and stability during a race, leading to reduced control, increased tire wear, and potentially compromising safety.

Flat tires alter a vehicle’s dynamics in several important ways:

Reduced Contact Patch: A flat tire decreases the contact area between the tire and the track. This reduction limits grip. According to a study by Smith and Johnson (2021), grip levels can decrease by up to 30% with a flat tire.
Compromised Handling: A flat tire affects the vehicle’s handling characteristics. The loss of air pressure can lead to unstable cornering behavior. This instability can result in oversteer or understeer. Oversteer occurs when the rear tires lose grip, causing the back of the vehicle to swing outward. Understeer is when the front tires lose grip, causing the vehicle to turn less than intended.
Increased Tire Wear: Flat tires increase friction during cornering. Higher friction leads to quicker tire degradation. This situation ultimately requires more frequent pit stops. The analysis by Thompson et al. (2022) found that tires can wear out up to 50% faster when driven flat compared to normal conditions.
Safety Risks: A flat tire heightens the risk of tire blowouts. Blowouts can lead to loss of vehicle control. The risk of accidents can increase significantly, especially at high speeds. Research by Walker (2020) indicates that nearly 40% of racing incidents are related to tire failures.
Impaired Speed: Flat tires contribute to speed loss. The drag experienced from a flat tire holds back acceleration and overall performance.

Flat tires have a larger contact patch with the ground, which may seem beneficial, but it can lead to instability. According to a study by the Tire Research Team at the Massachusetts Institute of Technology (MIT), tires at higher pressures provide better cornering stability and traction. When tires are flat, they may lose their ability to grip effectively, resulting in longer stopping distances.
Increased Rolling Resistance: Flat tires exhibit increased rolling resistance. Rolling resistance is the energy that must be overcome to keep the tires moving. A report from the National Highway Traffic Safety Administration (NHTSA) indicates that excessive rolling resistance can reduce fuel efficiency. In motorsports, this can lead to slower lap times. Flat tires can cause the vehicle to consume more energy to maintain speed, adversely affecting performance.
Increased Risk of Tire Damage or Blowouts: Flat tires carry a higher risk of damages or blowouts during operation. Tires designed for specific pressures are structurally engineered to handle various loads and speeds. A flat tire compromises this structure. Research conducted by the Tire and Rim Association has shown that operating tires below recommended pressure significantly increases the risk of blowouts, which can lead to loss of control and crashes.
Decreased Performance in Cornering: Cornering performance diminishes with flat tires. Proper tire pressure allows for the optimal transfer of forces between the tire and the road during turns. When tires are flat, the vehicle may slide, especially in high-speed situations. A study from the Society of Automotive Engineers (SAE) found that vehicles with under-inflated tires experienced considerable understeer, causing longer cornering times and reduced overall speed.
Potential for Hydroplaning in Wet Conditions: Flat tires have a higher tendency to hydroplane. Hydroplaning occurs when a layer of water separates the tires from the road surface, leading to a loss of traction.
