Stock on this truck are 6.50x20's in the front and 7.50x20's in the rear(dualies). Do I need to keep this same arrangement or can I run 6.50x20's in the rear as well?
I dont see why not,there only a little bit narrower than the 7.50's. The diam. may be a little smaller but will increase rpm's only slightly/ I would go with them if you already have them. ken ct omo
