Various online tyre / wheel calculators allow you to test tyre and wheel combinations. The first one listed (alloywheels.com) also gives you the range of rim sizes for each tyre. Best to avoid the extremes of the allowable range just to allow some room for error and avoid any odd handling effects, ie don't go for the absolute widest tyre allowable for any given rim size...


These calculators just compare the diameter of various tyre sizes....



I've got repro RS4 wheels and don't think they are as well made and finished as the OEM wheels plus the centre caps are not interchangeable wirthout a bit of adaptation. Still look the biz though!
