With the 10.5 in the back an offset of 23-25 is what you want. 25 may have a slight rub on the inside wheel well cover and 23 may stick out the fender a hair. My 10.5 has a 25 offset and fits perfect. I had to cut about 6 in. off the inside cover of the drivers side to remove the rubbing under hard corners.What is the reccomended rim/tire fitment on a 2017 challenger RT. I want to use a 315 tire in the rear with a 10.5 wheel. Offset?
