What these tire specs mean
Load Index 105 is the tire’s standardized carrying capacity, supporting up to 925 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 280 AA 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.
Summer tires are built for warm weather grip and should not be used as winter tires in Ontario or Quebec cold weather conditions.
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.
