245/45R18 Bridgestone Turanza ER300 RFT – Run-Flat
Run flat design keeps you moving after a pressure loss — requires a compatible vehicle and a working TPMS.
What these tire specs mean
- Load index 96 means each tire can carry up to 710 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 A 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.
- All Season tires handle mild year-round conditions well, but they’re not winter tires. In Quebec, a standard all-season doesn’t satisfy the mandatory winter tire requirement unless it specifically carries the 3PMS symbol.
- Run flat tires are reinforced to support the car’s weight after losing pressure, so you can drive a limited distance to get help. They only work on vehicles designed for run flats — compatible suspension and a working TPMS — so they’re not a drop-in replacement on most cars.
- 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.

Common questions — 245/45R18 Bridgestone Turanza ER300 RFT – Run-Flat All Season
What does the 245/45R18 tire size mean?
Break it down and 245/45R18 tells you three things: the tread is 245 mm wide, the sidewall stands at 45% of that — about 110 mm of rubber between road and rim — and it fits a 18-inch wheel. You’ll find this size most often on mid size SUVs, crossovers, and sport sedans.
Is the 245/45R18 Bridgestone Turanza ER300 RFT – Run-Flat an All Season tire?
Yes — the 245/45R18 Bridgestone Turanza ER300 RFT – Run-Flat is categorized as an All Season tire.

What does the 96Y rating mean on the 245/45R18 Bridgestone Turanza ER300 RFT – Run-Flat?
The 96Y on the Bridgestone Turanza ER300 RFT – Run-Flat breaks into two numbers: load index 96, meaning each tire carries up to 710 kg, rated to approximately 300 km/h; and speed rating Y, rated to 300 km/h under proper load and inflation. Your door jamb placard lists the minimum ratings your vehicle requires — match or exceed both.

Yes — the Bridgestone Turanza ER300 RFT – Run-Flat is a run flat tire. It’s reinforced to support the vehicle after pressure loss so you can drive a limited distance to get help.
