Dunlop RunOnFlat™ tyres utilise technology that allows you to drive up to 50 miles at a maximum speed of 50mph* on a flat or punctured tyre. Traditional tyres are likely to deflate or even fail in the case of damage, but the structured shoulder design of run flat tyres mean the weight of the vehicle can be supported for a short period of time – reducing the need to change the tyre at the side of the road.
* Unless vehicle manufacturers handbook advises otherwise.
RunOnFlat ™ tyres provide a whole host of benefits aside from the peace of mind of additional safety and convenience in the event of a puncture:
The following tyres from the Dunlop portfolio are also available with RunOnFlat Technology™:
A champion in grip and precision steering, as well as What Tyre UHP Tyre of the Year 2021.
Superb road feedback for responsive handling on wet and dry roads.
Precision handling, powered by DuPont™ Kevlar®. For high performance sports cars.
Dunlop RunOnFlat™ tyres are identifiable by the ‘RunOnFlat’ technology symbol on the sidewall of the tyre or ‘ROF’ text. Previous branding of this technology is also identifiable by the letters DSST which stands for Dunlop Self-Supporting Technology but works in the same way as RunOnFlat technology.
Other manufacturers may use different markings or symbols on the tyre sidewall to identify run flat technology over conventional tyres in the range. If you are unsure the vehicle handbook should identify if your car was originally fitted with Run Flat tyres. Unlike other features such as severe snow sutability that is featured on the new EU Tyre Label, Run Flat technology is not referenced via the tyre label.
RunOnFlat™ tyres can be fitted to standard alloy wheels, however the vehicle must be fitted with a Tyre Pressure Monitoring System (TPMS). This is because the design of RunOnFlat tyres means the stability and handling issues that would normally alert the driver to a puncture or sudden air loss are combatted so therefore it’s essential to receive a visual/audible alert on the dashboard via the TPMS. When the driver sees this alert on the dashboard it is crucial to minimise speed and journey length, failure to do so can compromise tyre sidewall strength causing potential damage to your alloys as well as impacting vehicle handling.
