245/40R20 Kumho Ecsta PS71-Max Performance Summer – Performance Summer
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 99 means each tire can carry up to 775 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
- Speed rating Y is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 300 km/h under correct load and inflation — not a target, just the rated ceiling.
- UTQG 320 AA A is a manufacturer-assigned grade for treadwear, traction, and temperature performance. Useful for comparing within the same brand — but it’s not a mileage guarantee, and ratings aren’t standardized across manufacturers.
- Summer tires are built for maximum warm-weather grip — dry and wet roads where compound stickiness and tread design matter most. They harden in near-freezing temperatures and are not suitable for Ontario or Quebec winter driving.
- 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.
- 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.
