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.
Every size series for this line carries the same grades in the NHTSA file. The size strings below are unchanged from that file.

Same line name under other brands
NHTSA stored this same line name under another brand string. A matching name is not evidence of rebadging, and it is not evidence the tires are the same product. The brand at the top of this page is the brand string in the file. The ratings list mispairs some line names with brands. See the data-quality note.
