I wonder if the 8 bolt patterns have changed over the years.
I need new rims. Have 16s in front and 18s (duals) in rear.
Would like 16s all around.
Maybe 18" rims must be used in rear to fit over hubs?
Thanks
If your truck is a factory dually then it came with the 18" 8 hand hole wheels in the 8x6.5" bolt pattern which is the same that GM used on 1 ton duallys until I believe 2010. Your studs are 1/2", 73-91 square body were 9/16" studs and 88-up were 14mm studs. The later wheels are probably what you have on the front but 16's will not fit on the rear if your rear brakes are the same size as on my 52 DRW. Some have talked about downsizing the rear brake to 3/4 ton 3600 rear brake because they are smaller and are said to fit 16's. If you leave the large rear brakes you will probably have to go up to 19.5's as mentioned above.
