  • What is the meaning of the codes on the sidewall of a tyre?

    The codes on a tyre give a great deal of detail about its type, construction and origin. The information of most interest to the average user is contained in a large, easily visible group of numbers and letters such as: 195/70 R16 91H

    195 = the width of the tread in mm.
    70 = the ‘aspect ratio' – indicating that the sidewall height is 70% of the tread width
    R = denotes that the tyre is of radial construction
    16 = the rim diameter in inches
    91 = the load-bearing index
    T = the speed index

Run-Flat Technology

  • Are all tyre dealers able to fit RFT tyres?

    Only RFT authorised dealers should fit RFT tyres due to the specialised equipment and training required. For more info click here

  • Are there any impacts on the other features of a car?

    No. Run-Flat systems do not have any major impact on other vehicle features. For more info click here

  • Can a tyre whose pressure has dropped to not less than 70 kPa be inflated and used as normal if no repair is required?

    Yes. But if an RFT tyre has undergone a significant pressure drop for any period of time Bridgestone recommend that tyres are inspected by an RFT authorised dealer. For more info click here

  • Can I repair a punctured Bridgestone Run-flat tyre?

    With certain types of punctures in the tread area, the Bridgestone Run-Flat Technology tyres may be repaired subject to certain conditions (Depending on how far and at what speed the car was driven after the puncture). Please consult your nearest RFT authorized dealer to have your tyres inspected.

    Before attempting a repair, consult the vehicle owner's manual for restrictions. The vehicle manufacturer may restrict the use of repaired tires on its vehicles. For more info click here

  • Can I use nitrogen instead of air to inflate the Bridgestone tyres equipped with Run-Flat Technology?

    Yes. For more info click here

  • Can tyres with Run-Flat Technology be fitted be fitted to any car?

    No, tyres with Run-Flat Technology should only be fitted to vehicles that are specifically designed for Run-Flats (Run-Flat Technology as standard equipment), or at least, cars designed with that option in mind (Run-Flat Technology as optional equipment). Any vehicle that uses Run-Flat Technology requires a Tyre Pressure Monitoring System or the driver might not realize that a tyre has been punctured. Furthermore, tyres with Run-Flat Technology are specifically tuned to the suspension of individual vehicles meaning they are inappropriate for fitment to other vehicles. For more info click here

  • Do I still have to check my tyre pressures if I have a Tyre Pressure Monitoring System (TPMS)?

    The function of a Tyre Pressure Monitoring System is to alert the driver in case of abnormal pressure drop (puncture) or too low pressure driving vs s a pre-set value. The fact of having a tyre pressure monitoring system installed, is no guarantee however you are driving on the correct tyre pressure. Bridgestone, as tyre manufacturer, recommends checking your tyre pressure at least once per month, to make sure pressure is in accordance with what is described by the vehicle manufacturer. For more info click here

  • Do tyres with the Bridgestone Run-Flat Technology have any effect on comfort or other performance when compared with standard tyres (handling, mileage, etc.)?

    Vehicles fitted with Run-Flat Technology have specially tuned suspension to compensate for the increased tyre rigidity that is a feature of tyres with RFT technology. All tyre performances though (comfort, mileage, handling) have been optimized for your vehicle in accordance with the requirements of the vehicle manufacturers. Meaning Bridgestone tyres with Run-Flat Technology do not perform differently from conventional tyres, but add on important safety value, which is keeping control and traveling you safely in case of puncture.

  • How can we detect a loss of tyre pressure?

    The vehicles Tyre Pressure Monitoring Systems (TPMS) alerts a driver when a tyre's pressure drops below agreed limits. Since Run-Flat Technology keeps tyres functioning for 80km (50 miles) at 80 km/h (50 mph) after losing pressure, a driver might not otherwise notice the loss of pressure. Therefore, any vehicle using tyres with Run-Flat Technology must be equipped with a tyre pressure monitoring system. For more info click here

  • How do I know if a tyre is Bridgestone RFT?

    A Bridgestone tyre with Run-Flat Technology can be identified by the RFT logo which appears on the sidewall of the tyre. For more info click here

  • How does a tyre pressure monitoring device work?

    There is a wide range of tyre pressure monitoring systems (TPMS) available so you should consult the vehicle manufacturer if you require a specific explanation. Basically there are two types of systems, indirect systems use the fact that reduced air pressure causes the wheel to rotate at a higher speed and when this occurs an alarm is triggered. Direct systems, directly monitor tyre pressure against pre-set values and send a warning when actual pressure falls below set values. For more info click here

  • How far can I drive after I am alerted to a deflated tyre?

    On Bridgestone tyres with Run-Flat technology one can continue its travel for up to 80km (50 miles) at a maximum of 80 km/h (50 mph), unless otherwise specified by the vehicle manufacturer. Owners should consult their vehicle handbook for details. For more info click here

  • If one of my Run-flat tyres sustains a puncture can I replace it with a standard tyre?

    Bridgestone do not recommend mixing tyres with Run-Flat Technology and standard tyres on the same vehicle, even if paired in axle sets. If you have a puncture, tyres with Run-Flat Technology are designed to permit you to proceed to a tyre dealer where you can have the tyre checked and replaced if necessary with another tyre with Run-Flat Technology. In exceptional and emergency circumstances a conventional tyre of the same size can be fitted. It must be noted that standard tyres do not have Runflat characteristics and should be removed at the earliest opportunity. For more info click here

  • My vehicle handbook states that my Runflat tyres can operate for 160km but all Bridgestone literature states 80km? Which is correct?

    As per definition (supplement 14th of UN/ECE Reg. 30) a "Run flat tyre" or "Self supporting tyre" describes a pneumatic tyre structure provided with any technical solutions (for example, reinforced sidewalls) allowing the pneumatic tyre, mounted on the appropriate wheel and in the absence of any supplementary component, to supply the vehicle with the basic tyre functions, at least, at a speed of 80 km/h (50 mph) and a distance of 80km (50 miles) when operating in flat tyre running mode.

    In practice, when applying tyres with Run-Flat Technology, vehicle manufacturers conduct tests on specific vehicle models, taking into consideration vehicle weight/characteristics and together with the tyre manufacturer can suggest a distance for that specific vehicle. For vehicles fitted with Bridgestone tyres with Run-Flat Technology as original equipment, the vehicle manufacturer's recommendations indicated in the owner's manual apply. For more info click here

  • What inflation pressure should I use for a tyre with Run-Flat Technology?

    Pressures for tyres with Run-Flat Technology are not by definition different than pressures for conventional tyres, but subject to what the vehicle manufacturer prescribes. For correct tyre pressures, always refer to the vehicle placard (usually located inside the driver’s side door or in the glove box), owner’s manual or handbook for the manufacturer’s recommendation. For more info click here
  • What is the effect on performance when my tyres with Run-Flat Technology are used in Runflat conditions?

    Unlike conventional tyres, a tyre with Run-Flat Technology is specially designed to hold to vehicle load in case of zero pressure. Provided the vehicle is operated within restricted Runflat speed of 80km/h, handling is only slightly impaired due to reduced cornering force. It is recommended that sharp driving maneuvers be avoided if the Tyre Pressure Monitoring System (TPMS) is triggered. For more info click here
  • What is the threshold pressure below which a tyre is deemed to have been Runflat?

    The international standard ISO 16992:2006 states that below 70 kPa an RFT tyre is deemed to have been run flat. For more info click here
  • What should I do when a loss of tyre pressure occurs?

    If the tyre pressure monitoring system signals that inflation pressure has been lost you can continue to drive with tyres equipped with Run-Flat Technology (RFT). Please follow instructions in the manual of your car and proceed to the nearest RFT authorised dealer to have your tyres inspected. For more info click here
  • Will Run-Flat Technology be widely used in the future?

    The demand for this kind of technology is increasing as awareness of safety and ecological concern rise year after year. Bridgestone continue to address safety and environmental issues through our products. For more info click here

Tyre Maintenance

  • How often should I check my tyre pressures?

    Pressures should be checked on a regular basis (at least once a month), or before embarking on a long journey. For more info click here
  • To what pressure should I inflate my tyres?

    The correct pressures for the front and rear tyres of your car will be indicated in the owner's handbook. Note that it is advisable to increase the pressures – again in line with the vehicle manufacturer's recommendations – when carrying heavier-than-usual loads. For accurate inflation, measure and adjust the pressures when the tyres are COLD.
    Remember also to check the spare tyre, which should be maintained at the higher of the recommended front/rear pressures (you can always release a little air, if necessary, when the spare is fitted). For more info click here
  • When is a tyre considered to be worn out?

    In Europe, the legal requirement is that the tread grooves retain a certain minimum depth, when measured at any Tread Wear Indicator (TWI), located around the circumference of the tyre. For summer tyres, the legal figure is 1.6 mm, while for winter models the advised minimum depth is 4 mm.

    It may nevertheless be advisable to change a tyre at an earlier stage if there is a discernible loss of grip or deterioration in handling performance – or if you are driving regularly at high speeds, under extreme weather conditions or over hazardous terrain.

    Tyre carcasses should be checked regularly, and replaced if you discover cuts or deformations indicating a weakness in the internal structure. If in doubt, consult your garage or tyre dealer.

    Even if not physically worn or damaged, the age of a tyre can also affect its performance. Oils incorporated into the rubber dry out over a period of time, making it less flexible – with the result that grip is reduced and braking distances increased. For more info click here
