Yes, bugger... I've had a number of punctures in numerous cars, but nothing is as bad as a 3in/75mm nail through the bottom and sidewall of one of my 19in Dunlop tyres (factory fitted) on my Captiva. I went to 4 tyre places and all stated that they could not repair the sidewall of any tyre, so I got quoted $575 for a shitty Dunlop replacement. For $60 more I replaced 2 new tyres with another brand (not much better) and keep the other tyre as a spare. Well, that spare (although a little worn) came in handy after 6 years.
So let us know what it cost to repair, or worst case, replace the tyre. I am sure we would all be curious...
