What these grades mean in plain English

  • Treadwear 360: this is a moderate treadwear grade, near the middle of NHTSA-rated tires. Under UTQG a grade of 200 should wear twice as long as the grade-100 control tire on NHTSA's test course; real-world mileage varies with driving, rotation, alignment and climate.
  • Traction B: B: middle wet-braking grade. Traction is straight-ahead wet braking only; it does not measure cornering or hydroplaning.
  • Temperature A: A (highest): resisted heat build-up through the higher 575 rpm test stage.
  • Ranked just above in Bridgestone: DUELER H/T 470 (median 360).
  • Ranked just below in Bridgestone: DUELER H/T 684 II (Trade) (median 360).
