    I had 265 70R19.5's on my 03 Dodge Dually. I am sure you can go to 245. Measure the distance between the duals.

    depends on how heavy you tow. you shouldnt have any problems with 245's and im sure you could go 265's, but again, it would depend on how much you weigh empty and with tounge weight on ya.

    I want to say I had 8" wheels. I will have to look. Mine were 10 lugs with adapters. Loved them. I will try and find a few pictures.

    6.75 inch. they are just as wide as the rim. the 245's and 225's look silly on my rims...

    Factory trucks usually have 6" wheels and 225s. I have 6.75" wheels on my 245s. I did lots of research and measured many wheels & tires before I purchased. I would have rather had 7.5" wheels. I have seen 245s on 7.5" wheels and they look REALLY good. The 245s on 6.75s still let the tread run flat. IMO the 6" wheels should only run 225s.
