Dodge is still staying with the old standard 8 on 6.5 lug spacing but I believe they had a smaller center hole than Ford or GM. Ford changed in 1999 with the new 8 on 170 pattern with the F250 "super duty" there was no 250 super duty prior to 99 and the 97 trucks were the same as the 96 trucks. The 98 F250's had an odd 7 bolt pattern if I remember right. Chevrolet used the 8 on 6.5 up until 2011 which is now an 8 on 180 just to make is more of a hassle to interchange wheels. My new HD is an 2011 and I am having a hard time finding wheels I like for it.
