245/40R20 General G-Max RS Summer
Category: Summer – Ultra High Performance
The General G-MAX RS is a summer ultra-high performance tire designed for grip in dry and wet conditions along with a strong center rib for crisp steering response. The silica-rich summer tread compound and directional tread grooves ensure wet grip by directing water away from the tread to avoid hydroplaning. Stabilitread Technology provides a larger footprint and optimized pattern stiffness to promote even wear and a built in wear indicator lets you know when to replace the tires. The G-Max RS has a single-ply casing with two-ply sidewalls and two steel belts to further enhance handling and high speed performance.
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 360 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.
- Vehicle Type helps identify whether the tire is intended for passenger, light truck, commercial, or similar service categories.
