My 05 rims are stock and they are 17in. but I also have the stock 17" aluminum rims off my 03. I am having the Kore system instaled on the Aug 17th... but just cant wait. I would have thought that the 37" tires would fit... because the lift brings the axle back... making it tighter in the back. With it lower (stock) it should push the axle foward and allow more room for the stock rim and a 37" tire.
