Can a tyre puncture be detected on a run flat?
Because of their reinforced sidewalls, it can be difficult to tell you’ve got a puncture if you’re driving on run flats. This means all vehicles that use these tyres must also have a tyre pressure monitoring system (TPMS) fitted. Often, an alert from this monitoring system is the only thing that indicates to drivers that they have a puncture.
What happens when a run flat tire goes flat?
Run-flat tires are still used today, using a reinforced sidewall that can support a vehicle’s weight after the tire experiences a total loss of air pressure. In theory, this should allow you to reach a service center to fix or replace the tire, but what actually happens when a run-flat tire goes flat?
Why are low profile tires not more prone to punctures?
