Are the 55' 2nd series GMC 150 3/4 ton dually wheel size and offset similar to the 3600 or 3800 dually setup.
I am having issues figuring out the right offset to fit my truck.
The problem is the truck is (6) hours away and I cant retrieve it until I replace the stock wheels and tires which I will do on site prior to loading it up.
The manual states my size is 16x6-8lug on 6.5 but I swear it is a 15" wheel.
