What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Which tires, by their DOT codes: the range is in the recall’s report on NHTSA’s site, not in this file. Check the code on your tire’s sidewall against it.
  • How many have been returned or fixed isn’t in the notice.
