What these tire specs mean
- Load index 128 means each tire can carry up to 1800 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
- Speed rating Q is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 160 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.
