285/45R21 Bridgestone Alenza Sport A/S RFT – All Season Run-Flat
Category: Truck/SUV All Season – Touring
The Bridgestone Alenza Sport A/S RFT is a run-flat all-season light truck and crossover/SUV tire made for drivers who want low-profile style tire options to enhance vehicle appearance while providing all-season capability. The Alenza Sport A/S comes as original equipment on some models of crossover and SUV vehicles and is meant to be driven for a short period when a puncture occurs to help the driver make it to a repair facility.
Run flat design allows you to still drive a short distance despite having a puncture. Must be used with a compatible vehicle and TPMS.
What these tire specs mean
Load Index 113 is the tire’s standardized carrying capacity, supporting up to 1150 kg per tire. Use it to confirm the tire meets or exceeds the load rating listed on your vehicle placard.
Speed Rating H indicates the tire’s maximum sustained speed capability under proper load and inflation. This is approximately 210 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.
Run flat tires can temporarily support the vehicle after pressure loss, allowing you to keep control and drive a limited distance to service. Note that they require a compatible vehicle setup and a working TPMS system.
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.
