Re: GT spare tyre
I have a GT 3.2 - 18 inch wheels. I actually purchased a compact spare wheel , jack and the fittings for the spare wheel. As shiny_car says the spare wheel will not fit on the front, but I thought I could swop things around.
A couple of months ago I received a letter and manual insert from AR saying that the use of the compact spare wheel is not permitted on the 3.2 models.
I suspect that the problem is not only the fitting on the front, but maybe the "stability control" (VDC?) and/or ABS gets confused and stops the car from being driven. I read somewhere that people had problems when fitting different size tyres on different wheels. The VDC locked up.
PS the full size wheel does not fit in the spare wheel cavity - the diameter is OK but it is too thick.
