The Amermac 975 Tire Warmer is the ideal way to warm and precondition tires prior to the tire truing or tire shaving process.  Tire warming is the process where tires placed are placed into the 975 Tire Warmer and spun for approximately 4 to 6 minutes. Heat is generated through friction during this process and rapidly raises the tire temperature which helps eliminate stationary flat spots.  Tire Warming is necessary for tires that have sat for periods of time, whether in a tire rack or on a vehicle can develop flat spots. This condition is more prevalent with bias ply tires, but also occurs with radial tires. The 975 Tire Warmer and preconditioning is also ideal for heat cycling racing tires.
