O/T a bit but are the tyre sealant/inflators not up to much? Short of having a huge blow out, are they not a good alternative?
Aye, blimey, no amount of foam will sort that! I know you can get the spare from Eurospares for something like £600. Ouch!.....my split was on the inside 10 inches long around the outside of the tread where it meets the sidewall....
