255/40R18 Michelin Pilot Sport A/S 4 – All Season
Category: All Season – Ultra High Performance
The Michelin Pilot Sport All Season 4 is an ultra high performance tire developed on the track and proven on the street. It has an asymmetric tread pattern that ensures even heat and traction distribution for a long tread life while providing more outer shoulder lateral grip and maximum levels of silica to stick to the pavement. Full depth sipes improve the Pilot Sport All Season 4's traction in wet and snowy condition and helped it become the first ever all-season tire chosen by Chevrolet for the Corvette. It also has a 70,000km tread life warranty for all sizes.
XL (Extra Load) rating supports higher inflation pressure and carrying capacity than standard load tires.
What these tire specs mean
Load Index 99 is the tire’s standardized carrying capacity, supporting up to 775 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 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.
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.
