With Sumitomo's S-Tech technology, the ST778 Plus SE is a premium steer axle tire that's engineered for long miles in line haul work. The ST778 Plus SE features a flat footprint, a rubber formulation that resists heat buildup, and an all-season tread pattern 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
  • Stone ejectors built into grooves to protect casing from damage
