hey man, not sure if your still looking for some info but currently running a 4/7 on my 1990 stepside with 18x8 in front 18x9.5 in rear, went with a 245/45 in the front and rolled the lip for extra clearance and did a 285/40 in rear and trimmed about 1/4" off the rear fiberglass lip being a stepside.

One of the handiest sites i have found! Take a little time to get all the info entered but I love this. You can play with different combos and get a good idea of what you want and don't want.
