I have the OEM 19" 230 rims and want to replace the runflats with some general exclaim UHPs from tirerack. The stock tires are 225/35/19 F and 255/30/19 R. Is it okay if I mount the available 235/35/19 and 265/30/19 on front and rear respectively? Tirerack has 225/35/19 F but they don't carry 255/30/19 R for Generals so that's why I looked towards the wider sizes. Will there be rubbing? I really have no idea what is and is not okay.
I found somewhere on the forum that the offsets of the 19" OEM rims are +37 and +39 if that helps any.
