The Bridgestone Driveguard All-Season Touring Run-Flat Tire features a load index of 87.0 and is designed for standard passenger vehicle use. While the specific speed symbol depends on the exact rim diameter and width configuration, the 87.0 load index provides the structural capacity to support the vehicle’s weight even at zero pressure.
The Bridgestone Driveguard utilizes a proprietary rubber insert to support the weight of the vehicle and an optimized contact patch to distribute that weight evenly. We selected this tire for our comparison because it offers a 60,000 mile limited mileage warranty and low-pressure mobility. For run-flat tires, verifying these ratings is critical because the internal reinforcement must handle the increased stress of supporting a vehicle’s weight without air. Buyers should note that while this tire handles standard loads, a higher load rating buffer is required for heavy towing or hauling beyond standard passenger capacities. If you install these on a different wheel offset, the physical leverage and stress distribution change, so you must confirm the specific load and speed symbols for your exact wheel size on the manufacturer’s compatibility page.
What to Check Before Buying Bridgestone Driveguard Tires
Confirm these technical requirements before purchasing to ensure the tires match your vehicle’s engineered limits:
- Verify that the 87.0 load index meets your vehicle’s specific weight requirements to prevent structural failure.
- Check your vehicle’s manual to ensure the speed rating matches the maximum engineered speed of your car.
- Confirm the specific load index and speed symbol combination for your exact rim diameter and width.
- Check if your tire pressure monitoring system (TPMS) requires specific calibration for run-flat compounds.
- Determine if your towing or hauling requirements necessitate a higher load rating than the standard passenger rating.
Choosing the Right Run-Flat Tire
The Bridgestone Driveguard is a touring tire with all-season performance, which functions as a reinforced tire that stays inflated and driveable after a puncture. This product is ideal for drivers who prioritize the safety of a 50-mile post-puncture range and a long-lasting mileage warranty. If you require a tire for high-performance sport driving or extreme weight distribution needs, you may need to look at options with higher load indices or specialized high-grip compounds that differ from this touring-focused model.
If you need a wider variety of options, compare the best run-flat tires for all-season driving to find your perfect match.
If you need a reliable all-season tire that provides low-pressure mobility and a long-term warranty for a standard passenger vehicle, the Bridgestone Driveguard is the appropriate choice.
