I was told that run-flat tyres can not be repaired and believe it after I've been shown how the tyre split. I had a puncture this summer and had to buy a new tyre.
I got a punture last week on my rear run flat tyre, brought it to Phoneix Tyres beside croke park. Was expecting to fork out for a new one which would have been €305 (18" wheels) - luckily enough they were able to plug it - they pulled out half a stanly blade which I picked up off the road - who throws these things on to a road ;-(
I only drove around 10 miles on the deflated tyre so no damage to the tyre; thankfully it was only €12 to plug.
