Garage - Tires

Tires are the single most important element in drag racing. The tire is what turns the power of the engine into acceleration and speed. Each tire on the car can be edited independently.

IHRA Drag Racing has several pre-built tires to choose from. Selecting a pre-set tire will automatically set all of the tire characteristics except camber and won't affect the tire adjustments. You can create your own tire by adjusting the following attributes:

Peak: This is the maximum force that the tire can exert.

Slope: This represents how quickly tire forces are generated as slip angles are increased.

Stiffness: This value represents the stiffness of the tire or how fast the tire develops its forces.

Shape: This represents the shape of the tire curve at its peak.

Curvature: This represents the type of force curve generated by the tire.

Camber Slope: This value represents how quickly camber affects lateral force.

Camber Angle: Camber will change the lateral force generated by a tire and has small effects on the longitudinal forces.

The tire can then be adjusted for the car by selecting the following adjustments:

Diameter: This is the static diameter of the tire.

Growth: Tire growth is a measure of how much the tire grows as RPM increases.

Pressure: This is the tire pressure. Pressure affects the tire grip, temperature, and spring rates.
