What these grades mean in plain English

  • Treadwear 700: this is a very high treadwear grade, the top end of the UTQG scale. 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 A: A: second-highest wet-braking grade. Traction is straight-ahead wet braking only; it does not measure cornering or hydroplaning.
  • Temperature B: B: passed the 500 rpm stage but not the 575 rpm stage.
  • Ranked just above in Big O: LEGACY TOUR PLUS (S & T RATED) (median 720).
  • Ranked just below in Big O: LEGACY TOUR PLUS 60/65/70 SR (median 660).

What is the treadwear rating of the Big O LEGACY TOUR PLUS?

NHTSA's UTQG data lists treadwear grades from 380 to 700 (median 700) for the Big O LEGACY TOUR PLUS, from 18 records. Treadwear is graded in multiples of 20 relative to a government control tire graded 100; it is not a mileage guarantee.

Is the Big O LEGACY TOUR PLUS treadwear grade high or low?

A grade of 700 is a very high treadwear grade, the top end of the UTQG scale. Compared with every line in the NHTSA data, the median is higher than 95% of lines (dataset median 420). Within Big O it ranks #4 of 50.

What is the cost per mile of the Big O LEGACY TOUR PLUS?

We do not have a licensed price or warranty-mileage feed yet, so we do not state a cost per mile. Use the formula cost per 1,000 miles = price per set ÷ (expected miles ÷ 1,000) with your own quote and mileage expectation, or the calculator on this page.
