275/50R21 Michelin Primacy AS All Season
XL (Extra Load) rating supports higher inflation pressure and carrying capacity than standard load tires.
What these tire specs mean
- Load Index 113 is the tire’s standardized carrying capacity, supporting up to 1150 kg per tire. Use it to confirm the tire meets or exceeds the load rating listed on your vehicle placard.
- Speed Rating Y indicates the tire’s maximum sustained speed capability under proper load and inflation. This is approximately 300 km/h under proper load and inflation.
- UTQG 540 A A is the manufacturer treadwear, traction, and temperature grading system. It is useful for comparing tires from the same brand, but it should not be treated as an exact mileage promise.
- All Season tires are made for mild year round driving, but they generally do not meet Quebec winter tire requirements unless they also carry 3PMS.
- XL means Extra Load. These tires are designed to carry higher loads at higher inflation pressures than a standard load tire in the same size, which matters for heavier vehicles, loaded vehicles, or factory fitments that require XL.
- EV Compatible means the tire is marked as suitable for electric vehicles, where load, torque, rolling resistance, and noise can matter more.
- Vehicle Type helps identify whether the tire is intended for passenger, light truck, commercial, or similar service categories.
- Warranty coverage is manufacturer backed and depends on normal use, proper maintenance, rotation, inflation, and alignment conditions.
