qaisar Posted August 11, 2004 Share Posted August 11, 2004 saw program yesterday on men and motors where they drilled a hole in a bridgestone tyre and continued to drive it quite aggressivley around a "track" (bunch of cones set up to make a track) tyres were on a BMW Z4 and the guy seemed to be able to drive normally and even took his hands off the steering wheel to show puncture didnt affect handling. Didnt catch the model of the tyres, but apparently able to do 300 miles after puncture with no effect. point being dont need to carry spare as can drive to nearest tyre shop/home to swap anyone heard of this tyre? not sure whether it would cause any damage to alloy while driving with the puncture but presume not if the handling wasnt affected Quote Link to comment Share on other sites More sharing options...

Nick_TC Posted August 11, 2004 Share Posted August 11, 2004 They're called Run Flat tyres, as Bob said. A few firms make them these days, hard ride due to the sidewall basically being solid. Designed to be driven on incase of a puncture, hence the name. Quote Link to comment Share on other sites More sharing options...

Sherriff Posted August 11, 2004 Share Posted August 11, 2004 How would you know you had a puncture if the tyre didn't go down and it didn't affect the handling? You'd perhaps do 300 miles before you realised and then you'd be stuck with a knackered runflat? I don't have a spare anyway, just a massive can of tyreweld and a recovery card if it really goes Pete Tong. Sherriff. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted August 11, 2004 Share Posted August 11, 2004 As far as I am aware you can have any tyre treated with a run flat solution that does very similar to tyreweld filling the usual air gap with some expanding filler type affair. Its also supposed to prolong tyre life by 10% if you beleive the hype. Quote Link to comment Share on other sites More sharing options...
SimonB Posted August 11, 2004 Share Posted August 11, 2004 Yeah, that stuff is crap though unless you have a very small puncture it's useless. Run flats actually do depressurise, but still work OKish thanks to the very stiff sidewall. But as Nick said, that makes the ride awful and messes up the handling. You wouldn't notice on a Z4 because the rise is so damn awful anyway! If you read Evo magazine they're always going on about how swapping the standard run-flats on some of their fast fleet cars for normal tyres makes them handle much better.

Nick_TC Posted August 11, 2004 Share Posted August 11, 2004 Tif Needle and Vicky Butler 'funny lip' Henderson also done the same sort of test a while ago IIRC, again on a beemer, 3 series I think........................I see a pattern forming Quote Link to comment Share on other sites More sharing options...
