Get technical:

With Sumitomo's S-Tech technology, the ST778 is a premium steer axle tire that's engineered for long miles in line haul work. The ST778 features a flat footprint and an all-season tread, with grooves and microgrooves that direct water away to resist hydroplaning.



Features & Benefits

  • Wide footprint puts more rubber on the road to reduce uneven wear
  • Designed for use on the steer axle of commercial trucks and buses
  • Steel belted construction increases strength and durability
  • Tread pattern allows for solid traction and performance year-round
