A good fit if you
- Cold weather, snow, and ice — the conditions this tire is specifically engineered for.
- Drivers who want the best cold-weather performance and won’t compromise with all-seasons.
- Factory fitments or vehicles that specifically require XL-rated tires.
Think twice if you need
- Summer use — winter compound softens too much in heat, wearing faster and handling worse.

275/40R21 Bridgestone Blizzak 6 Winter
Carries the 3PMSF symbol — tested and rated for severe snow service. XL (Extra Load) — built to handle higher inflation pressures and heavier loads than a standard-load tire of the same size.
What these tire specs mean
- Load index 107 means each tire can carry up to 975 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
- Speed rating W is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 270 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.
- XL means Extra Load. These tires run at higher inflation pressures and handle more weight than a standard-load tire of the same size. If your vehicle’s factory spec calls for XL, that’s what you need — swapping to standard load can affect ride, handling, and safety.
- 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.
Where this tire fits in
The 275/40R21 Bridgestone Blizzak 6 is a winter tire, built around a 275 mm section width for a 21-inch wheel.
In practical terms, this size gives you a 40-series sidewall of about 110 mm paired with a 21-inch wheel diameter — confirm this against your current tire’s sidewall marking before ordering.
Worth noting on the spec side: this tire carries 3PMS certification for severe snow service, an XL extra load rating, load index 107 and speed rating W (~270 km/h).
About the 275/40R21 tire size
The 275/40R21 breaks down into three numbers:
- 275 — tread width in millimetres, measured across the contact patch
- 40 — sidewall height as a percentage of the tread width (roughly 110 mm of rubber between road and rim)
- R21 — radial construction, for a 21-inch wheel
The 275/40R21 size is commonly found on performance vehicles and heavy duty trucks. Replacing a set? The full size marking is on your current tire’s sidewall — confirm width, profile, and rim diameter all match before you order.

Ontario & Quebec — winter tire rules
In Quebec, winter tires are mandatory on all passenger vehicles from December 1 to March 15 — it’s the law under the Highway Safety Code, not a suggestion.
