Is your car lowered rjm180. If its on standard suspension you should be ok with a 255 tyre, on mine because it is lowered a 255 would be too big, plus I prefer the look of a lower profile tyre. Can you get to the place selling the wheels and try one out.
Ok thanks very much Pabs.
My car is of stock S4 height, ride, suspension.
I have 235 40 18's on it at the moment as standard.
With stock suspension etc, is a 255 35 19 tyre going to fit ok and will this depend on the ET rating? If so what ET will work with the 255 tyre?
I want to use a 255 tyre as they are available with at least the correct load rating for my car, 95y XL.
Will a 9J size alloy fit my car ok or does it have to be a maxinum of 8.5J with the 255 tyre. I'm happy with 8.5J anyway but more choice if 9J is suitable.
Pabs, when you say your spare would not fit in the spare wheel well, would a 255 35 19 on a 8.5 j and a 255 on a 9J fit ok.
Lastly, i dont really want to use spacers as ive heard a few negative things about them but i may have to use spigot rings as the centre bore sizes seem to be different. Are spigot rings in general safe to use and if Audi did work on the car are they ok to refit wheels that have spigot rings or would they frown and not go near them.
Aplogies for so many questions that have probalby been covered a million times before.
Many thanks in advance
