About this data
These are rows in NHTSA's ratings list, under the brand string that list stores. The list does not say whether a tire is still sold, and it has no category field. Light-truck tires, deep-tread winter-type snow tires, and temporary spare tires are outside the UTQG rule, so a missing line is not a grade. Sorting these rows is an ordering of NHTSA's list, not a ranking of the best tire. Data last verified October 21, 2026 (UTC). Data-quality notes.
Grades can differ by the size series NHTSA published. Size text is shown as published, not converted into a standard size code.
