Check the air pressure in your tires (including spares) monthly and before long trips or carrying extra weight. Be sure to use an accurate pressure gauge. Check inflation pressure when the tires are “cold.” Tires are considered “cold” when the vehicle has been parked for three hours or more, or if the vehicle has been driven less than a mile (1.6 km) at moderate speed.
Always keep the vehicle manufacturer’s recommended inflation pressure in your tires, including the spare. Check the pressure in your tires monthly and before long trips or carrying extra weight.
A tire bearing a letter “speed rating” indicates the tire’s speed capability according to standardized lab tests. The speed rating system is intended to permit comparison of the speed capabilities of different tires. When replacing your tires, consult your vehicle owner’s manual and tire information placard for recommendations, if any, concerning the use of speed rated tires.
If you see damage or an unusual condition, have your tire inspected by a qualified tire service professional. It may be necessary to have it removed from the wheel for a complete inspection.
Nitrogen is an acceptable inflation gas for use in Bridgestone and Firestone passenger, light truck, and truck tires. Bridgestone has no comment on the various performance claims made by Nitrogen suppliers.
Removing and replacing tires on wheels can be dangerous. Attempting to mount tires with improper tools or procedures may result in a tire explosion causing serious personal injury or death. This is only a job for a qualified tire service professional. Never perform tire service procedures without proper training, tools, and equipment.
Bridgestone brand Run-Flat Tires are marked on the sidewalls, near the wheel, with the RFT logo.
Follow your vehicle manufacturer’s recommendation for inflation pressure settings as indicated on the vehicle tire information placard and/or in the vehicle owner’s manual. Like other tires, RFT tires need proper inflation pressure maintenance for safe operation and to achieve maximum tire life and performance. Check inflation pressures monthly and before long trips or carrying extra weight. Use an accurate tire gauge and check pressures when the tires are cold. Tires are considered “cold” when the vehicle has been parked for three hours or more, or if the vehicle has been driven less than a mile (1.6 km) at moderate speed.
Do not replace or mix RFT with conventional tires, unless on an emergency/temporary basis. Conventional tires do not have run-flat capability and the handling characteristics of the vehicle with these tires may be different. If a conventional tire is used on an emergency/temporary basis, verify that its size, load capacity, inflation pressure, and speed rating specifications meet the requirements of the vehicle. Replace any conventional tire with the proper RFT as soon as possible.
A functioning Tire Pressure Monitoring System (TPMS) must be used with your RFT. Because these tires ride so well even without inflation pressure, the TPMS may be necessary to alert you of an inflation pressure loss condition. When alerted, follow the instructions in your vehicle owner’s manual.
Your RFT will be marked on the sidewall with run-flat or low tire pressure operating speed of 50 mph (80 km/h). If the sidewall indicates a distance limitation, do not exceed that number. If the sidewall does not specify a distance limitation, consult your vehicle owner’s manual as run-flat or low tire pressure operating limitations vary by tire design and vehicle applications. Note: Maximum distance values are determined under controlled conditions, which may vary in actual use. Your distance capability may be less, or more, depending on your specific operating conditions. If in doubt, do not exceed the 50-mile (80 km) limitation. Seek tire service as soon as possible to minimize tire damage.
No tire, regardless of its design or quality, is indestructible. RFT can be rendered unusable due to a puncture or other road hazard as well as from improper tire pressure maintenance. Some punctures may be repaired under certain restrictions and prescribed procedures. In addition to low pressure, the factors affecting ability to repair an RFT include: vehicle speed, load, and maneuvering; the amount of inflation pressure loss; and ambient temperature. In any situation, the extent and location of a puncturing object or other road hazard are also critical factors. Run-Flat Certified Retailers will fully inspect your tire, inside and out, to determine if the tire can be repaired. Tire damage is not always visible from the outside and the tire must be removed from the wheel for a complete inspection. Note: Some vehicle manufacturers do not recommend using repaired tires. Consult your vehicle owner’s manual or contact the vehicle manufacturer before operating a vehicle that has a repaired tire.
DriveGuard is the first full line of run-flat tires available for coupes, sedans and wagons not originally equipped with run-flat tires and allows drivers to travel up to 50 miles at a maximum speed of 50 mph after a puncture even with low pressure or complete pressure loss.
Speed Rating: H, V, W
Sizes: 32 sizes
Rim Sizes: 15" to 19"
DriveGuard is not currently available for CUVs, SUVs, minivans, vans or any vehicle without a TPMS System.
DriveGuard is classified as an Eco product. The Eco-Products designation shows these tires have the following characteristics:
And one or more of:
*As compared to the Potenza G019 Grid.
DriveGuard tires allow you to drive up to 50 miles at a maximum speed of 50 mph after the loss of tire pressure due to a puncture.
The TPMS should alert you. See the next question for more details.
Take note of your odometer when your TPMS light comes on. We suggest that you set your tripometer to zero (if available) when the TPMS goes off in order to help you estimate your distance traveled.
No, because no tire, regardless of its design or quality is indestructible. DriveGuard tires can be ultimately rendered unusable due to a puncture or other road hazard as well as from improper pressure operation.
DriveGuard significantly reduces the likelihood that the driver will need a spare tire.
Each DriveGuard tire is engineered with a reinforced sidewall and proprietary Cooling Fin Technology which allows it to hold its shape and support the weight of a vehicle, even with low pressure or complete pressure loss, for up to 50 miles at a maximum speed of 50 mph.
DriveGuard tires that have been operated with less than 15 psi (100 kPa) inflation pressure should not be repaired. Other repair restrictions apply. See Tire Maintenance, Safety and Warranty Manual for full details. Check tire pressure with a gauge every month and before long trips or when carrying extra load. Determine the cause and extent of an inflation pressure loss as soon as possible, especially after an alert from the tire pressure monitoring system (TPMS).
The purpose of the tire pressure monitoring system (TPMS) in your vehicle is to warn the driver that one or more tires is/are significantly under-inflated and creating an unsafe driving condition. The TPMS low tire pressure indicator is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tire cross-section (that resembles a horseshoe) with an exclamation point.
