The main reason I have asked is that I got a nail in a new tyre - a runflat. No one would repair it so it was £100 for a new tyre. Also the wear rate on them is rubbish compared to a normal tyre. A bloke at work has a 118d M sport so has the 18 inch low profiles and he stuck with runflats but is only getting 10000 miles out of a set of the pirellis. Driving on the runflat was awful too. I have covered 250000 miles and never had a blowout and have only once had a completely flat tyre. So I thought I would fit normal tyres and stick a compressor in the boot and a can of tyre weld. Then at least I can get a puncture repaired for £15 and get going again.
