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. Why a tire may have no UTQG rating. Sorting these rows is an ordering of NHTSA's list, not a ranking of the best tire. Data last verified November 9, 2026 (UTC). Known errors. Data-quality notes.
In the NHTSA UTQG file verified November 9, 2026 (UTC), 5,628 of 7,622 grade rows are size-specific and 1,994 say all sizes. A row is all sizes only when the size text, with extra spaces collapsed, is “all”, “all size”, or “all sizes”. Any other text, including “all sizes except” and a named size, is size-specific. The size text is shown as published.
The same file has 8 invalid grade rows and 2 suspect grade rows. Invalid means traction is outside AA, A, B, and C, temperature is outside A, B, and C, or treadwear is not a whole number. Suspect means treadwear is 0 or not reported, and the row is not already invalid. These are the same checks as the known-errors page. The table flags the rows. The data-quality control can hide them or show only those rows. Hiding a row does not remove it from the file.
The address keeps the filters, so a link can be shared. Filtered addresses use the canonical URL of this page. The CSV is built in the browser from the filtered rows. It names the NHTSA UTQG file and the verified date. It is not a ranking, and a row does not mean a tire is on sale.
Compare two to four tire lines from this list. The tool keeps the chosen lines in the address so the comparison can be shared. A shared address points back at the tool page. Example comparisons are linked from the tool.
