275/40R20 Toyo Proxes ST III All Season
Category: Truck/SUV All Season – Sport
The Toyo Proxes ST III is a sporty all-season tire built for light trucks and SUVs that provides a balance of good looks and excellent performance. An all new directional tread design improves wet breaking distances by using a silica-based tread compound and increasing the tread width. The Proxes ST III has multi-wave sipes, directional should blocks, and lightning grooves that enable faster water evacuation, improve driving stability, and minimize tread wear for a smooth and quiet ride. It also has a 65,000km 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 106 is the tire’s standardized carrying capacity, supporting up to 950 kg per tire. Use it to confirm the tire meets or exceeds the load rating listed on your vehicle placard.
- Speed Rating W indicates the tire’s maximum sustained speed capability under proper load and inflation. This is approximately 270 km/h under proper load and inflation.
- UTQG 500 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.
- 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.
