235/45 R18 will fit on Audi A6 C6 2007

Hi everybody,

I found a good price on 4x Audi S6 18 Rims, witch comes with 234/45 R18 winter tires... the rims specs are 7.5J x18 ... I want to use these rims for the summer season and i looked on Audi rims measurements and there are not there... the standard is 245/40 R18... i know for these tyres i need 8J x18...

Should i go for 235/45 R18?

P.S. i've attached a photo of the rims...

235/45 should not be on a 7.5J rim, they should be on 8-9.5J - so the S6 wheels have the wrong width (too wide) tyre on for a start. A 225 will fit a 7.5J rim. As to whether the rims will fit, what is the offset (ET) number on them compared to the standard wheel? You need that as well to be sure.
