GT Radial GT978+ 385/65R-22.5

The long haul GT Radial GT978+ tires for trailers are suitable for mixed use. They feature a ribbed tread design that minimizes rolling resistance for better fuel economy. The wide base footprint on these tires offers resistance to irregular wear. Zigzag circumferential grooves expel water to prevent hydroplaning and add bite for better grip. The wide grooves also provide self-cleaning capabilities. Upper sidewall protection and enhanced shoulders prevent damage from curbing.

Features & Benefits

  • Wide tread design offers superior mileage performance
  • Robust casing for prolonged service
  • The deep treads also ensure longer tire lifespans
