I think the Audi is bigger than the Astra but you could be right,yes you can see some of the wheel but their bus has not been lowered O0 O
Ahh then it might be an issue on a lowered bus, although I think the A3 had a 15" spacesaver (cant check as I sold it last wednesday), it was definately smaller than the 18" alloys fitted. My apologies ;D
A mate has bought a new 5series beemer. no tyre weld or pump or spare wheel. Has RUN flat tyres. not sure if you can get these for a bus wheel fit. They also cost a fortune. £250 per wheel on the 5 series but are an option or £5 foam canister. much better and fits in the glove box/tool box
Someone on here had a flat whilst on holiday in Scotland. They had a can of tyre-weld. It failed. They called out their recovery company and guess what. They were charged for a call-out because they had no spare. I think it was about £180.
