Runflat Tyres VS Seal Tyres Runflat tyres have a bad reputation; they’re known for having poor ride comfort, tramlining, noise, low levels of wet grip, and if you puncture them very few places will actually repair a runflat due to the risk of sidewall damage. One new runflat tyre which nearly solves the runflat comfort and grip issues is the Bridgestone DriveGuard. (full report) This new type of runflat can be fit to any vehicle, and offers a very similar general experience to a regular tyre, but will still deflate in the event of a tread puncture.
