DriveGuard FAQ's

What are Bridgestone DriveGuard tyres?

DriveGuard is the first full line up of tyres designed for any passenger car¹ that allows the driver to maintain control after a puncture and safely continue driving for 80 km at up to 80 km/h². In addition, DriveGuard® delivers the highest rating in wet grip performance with short braking distances³.

Why did Bridgestone decide to launch the DriveGuard product?

At Bridgestone, we believe that Run-Flat Technology should not be limited to use on luxury or high-performance vehicles, so we have been perfecting RFT technology in order to produce the first full line of  touring tyres with run-flat capabilities which can be applied to any passenger car¹ that did not originally come with run-flats. Furthermore, there are now enough TPMS-equipped vehicles on the road to create sufficient demand for an after-market tyre with run-flat capabilities and we are proud to be the first tyre manufacturer to bring RFT  to a wider range of drivers and vehicles.

How does DriveGuard work?

Each DriveGuard tyre 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 for 80 km at up to 80 km/h after a puncture².

Who is likely to be interested in DriveGuard tyres?

Safety-minded drivers, women and families with young children.

What is a TPMS?

The purpose of the tyre pressure monitoring system (TPMS) in your vehicle is to warn the driver that one or more tyres is/are significantly under-inflated and creating an unsafe driving condition. The TPMS low tyre pressure indicator is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tyre cross-section (that resembles a horseshoe) with an exclamation point. 

Is a TPMS required for DriveGuard?

Yes.  A functioning tyre pressure monitoring system (TPMS) must be used with your DriveGuard tyres.  Because these tyres perform so well, even without inflation pressure, a TPMS may be necessary to alert the driver that they have lost air pressure.

Do all vehicles come equipped with a TPMS?

Since 1st November 2012, all new-type vehicles have been required by EU law to have a pressure based tyre pressure monitoring system installed. This applies to the road wheels, not the spare. Since 1st November 2014, all new passenger vehicles have to have a TPMS installed by the manufacturer. Many car manufacturers already introduced TPMS to their vehicles ahead of the 2012 legislation change. Cars without TPMS from original equipment can have one of many TPMS systems available in the retail market installed to enjoy the benefits of DriveGuard.

For which vehicles are DriveGuard intended?

DriveGuard is intended for any passenger car with TPMS, including those that did not originally come fitted with run-flat tyres (such as VW Golf, Peugeot 308, Renault Megane, Toyota Auris, Skoda Octavia…). DriveGuard is currently not available for SUVs, minivans, vans or larger Cross Over Utility Vehicles.

Can I use DriveGuard tyres with any kind of TPMS ?

Yes, you can.

Can vehicles currently using run-flat tyres switch to DriveGuard?


Does DriveGuard eliminate the need for a spare tyre?

DriveGuard significantly reduces the likelihood that the driver will need a spare tyre.

If I already have run-flat tyres on my vehicle, can I replace two tyres instead of all four?

Yes. While we always recommend replacing tyres in sets of four or in pairs on an axle for better performance, if the vehicle is already equipped with self-supporting run-flat tyres, we do not restrict mixing DriveGuard with those tyres so long as all other tyre replacement guidelines are followed.

What should I do when the TPMS light comes on?

  • Reduce speed as much as safely and reasonably possible; do not exceed 80km/h. The greater the speed, the less distance the tyre can travel.
  • Avoid abrupt or aggressive acceleration, braking, or cornering maneuvers as much as safely and reasonably possible. Pot holes and other road hazards should be avoided. Careful driving limits potential damage to the tyre, wheel, and vehicle.
  • Proceed to a safe and convenient location for tyre service as soon as possible. Take note of your odometer; your operation distance is limited. Do not exceed the 80km² in low pressure operation.
  • If an unusual vibration or vehicle handling difficulty arises, stop driving as soon as safely and reasonably possible. The tyre may be about to suddenly fail. Release the accelerator and gradually reduce speed. The tyre must be replaced before proceeding.
  • If towing a trailer, stop driving as soon as safely and reasonably possible. In this condition, it is potentially dangerous to operate a vehicle/trailer combination. If possible, disconnect the trailer and proceed as noted above. Do not continue to tow any trailer until proper tyre service or replacement has been performed.
  • Do not touch a tyre recently run-low or run-flat (it may be very hot). Allow the tyre to cool before handling.

How far can I drive on DriveGuard tyres after a puncture or loss in tyre pressure?

80 kilometres at maximum speeds of up to 80 km/h. Driving distance after a puncture may vary depending on vehicle load, outside temperature, and when the TPMS is triggered.

How will I know if I get a puncture or start losing air in my tyres?

First, please verify if your car has TPMS. If it does, the TPMS will alert you.

Should I drive more than 80km after a puncture?

No, because no tyre, regardless of its design or quality is indestructible. DriveGuard tyres can be ultimately rendered unusable due to a puncture or other road hazard as well as from improper pressure operation.

Are there any conditions in which DriveGuard tyres might not travel 80km after a puncture?

Factors affecting run-flat or low tyre pressure operating distance include vehicle speed, load, and maneuvering; the amount of inflation pressure loss; the extent of any tyre damage; and ambient temperature. To maximize the distance capability in a run-flat or low pressure condition:

  • Reduce vehicle speed as much as safely and reasonably possible. Do not exceed 80 km/h.
  • Avoid abrupt or aggressive acceleration, braking, or cornering manoeuvres as much as safely and reasonably possible; avoid pot holes and other road hazards.
  • Higher vehicle loads (such as with more passengers or cargo) and higher ambient temperatures decrease the distance capability of a DriveGuard tyre in run-flat or low pressure operation.
  • In the case of a delay in the TPMS being triggered (e.g. in the case of a slow loss of tyre pressure), you may have already travelled some kilometres in a run flat condition. We therefore recommend that you proceed to a safe and convenient location for tyre service as soon as possible after the TPMS has been triggered.

Are DriveGuard tyres repairable?

Yes, but provided the tyre does not show inside the innerliner wrinkles or innerliner abrasions or “debris”. Please note that from a repairability point of view, a DriveGuard tyre has to be considered as any normal tyre, and so any repair is under the legal and technical responsibility of the person who makes the repair. After any repair, Bridgestone takes no responsibility for the performance of the tyre.

How many kilometres can I drive with the TPMS on so that the tyre is still repairable?

The condition of the tyre after the puncture or pressure loss will determine whether it can be repaired. Please consult your tyre dealer on whether the tyre is repairable.

What do you consider to be a tyre failure ? Or sudden airloss ? Can a DriveGuard tyre cope with everything ?

Tyre failures that DriveGuard tyres are able to cope with are virtually any damage that a tyre may suffer (punctures, cuts or cracks) wherever occurring in the tread or side area caused by nails, screws, sharp stones, pieces of glasses, steel plates, metals, potholes, kerbs, etc …, which may cause sudden or slow airloss. In case the tyre has been completely shredded, obviously the tyre/rim needs to be replaced on the spot.

How does the performance of DriveGuard compare to conventional tyres?

Unlike conventional tyres Bridgestone DriveGuard® allows you to maintain control after a puncture and safely continue driving for 80 km at up to 80 km/h². In addition, DriveGuard® delivers the highest rating in wet grip performance with short braking distances³ and delivers comparable wear life and ride comfort.

Is Driveguard as comfortable as a normal tyre ?

DriveGuard tyres are comparable with conventional tyres in terms of comfort.

Will run-flat tyres be widely used in the future?

Bridgestone believes that DriveGuard will create a broader demand for mobility solution tyres as TPMS penetration increases in the car park and customers demand safety in all conditions. We are planning to release additional sizes in the future.

How can I find out if DriveGuard comes in the size I need?

Input your vehicle information into the tyre selector  which can be found on:\driveguard.

Does DriveGuard have the same guidelines for tyre service life as a conventional passenger tyre?


Does DriveGuard have the same guidelines on minimum tread depth for required replacement as conventional?


Does DriveGuard have the same rotation recommendations as conventional tyres?


Can I mix DriveGuard tyres with other tyres?

Yes but :

  • Bridgestone recommends fitting 4 DriveGuard tyres in order to obtain the full benefit and safety features
  • Bridgestone cannot guarantee the same driving performance if DriveGuard is mixed with other products

Is special equipment required to mount or demount DriveGuard tyres?

Most tyre retailers have the suitable equipment but should check their manufacturer’s information if they are unsure whether their tyre-changing equipment is suitable for run-flat tyres.

Can DriveGuard tyres be mounted on standard rims?


Can DriveGuard be fitted on all passenger car wheel rims?

Yes, as long as the size fits.
