Commercial Tire Maintenance: TPMS Calibration, PSI Management, and Blowout Prevention
🛡️

Tires represent the second highest operating expense for commercial trucking fleets behind fuel. Under-inflation creates excessive heat buildup, leading to rapid casing degradation and catastrophic tread separation.
Proper Cold PSI Maintenance
Check tire pressure when tires are cold using a calibrated digital dual-foot pressure gauge. Steer tires should maintain manufacturer-recommended 110–120 PSI, while drive and trailer duals should be equalized at 100–105 PSI to prevent unequal load transfer.
