I beleive the fronts are 17x7 w/ 215/40's. The rears are 17x8 with 245 or 255/60's. The wheels are Riddler's, a Chinese knock off but the price is right. This will be the 4th summer running those rims. And they have held up well, the roads here in SE michigan are a terrible pot hole ridden mess and I've nailed a few potholes over the years and the wheels are still spinning true. Unfortunately they do not make these Riddlers in a 18" wheel, I would like to put 18's on the back to fill up the wheel well a litte more. Josh-
