What these tire specs mean

  • Load index 121 means each tire can carry up to 1450 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
  • Speed rating R is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 170 km/h under correct load and inflation — not a target, just the rated ceiling.
  • Winter tires use a softer compound that stays pliable in cold temperatures, where all-season rubber starts to harden. They carry the 3PMS symbol and meet Quebec’s winter tire mandate.
  • 3PMS stands for Three Peak Mountain Snowflake — a symbol earned by meeting specific severe snow traction standards in testing. It is the mark Quebec requires for winter tire compliance.
  • Vehicle type indicates the service category this tire is built for — passenger car, light truck, commercial, or other. Matching the right category matters for load capacity, handling, and safety.
  • Warranty coverage is backed by the manufacturer and applies under normal use — regular rotations, correct inflation, and proper alignment. Keep maintenance records if you ever need to make a claim.
