Methodology

UTQG treadwear, traction, and temperature grades are supplied by tire manufacturers under a NHTSA-specified test. They are useful official reference grades, but they are not mileage promises and cross-brand comparison is imperfect.

Cost calculator: estimated miles = treadwear x 100. This is labelled a manufacturer-relative estimate.
