Does anyone know the off set of 1994 Chev. 6 lug wheel? I want to upgrade the wheels and tires on my travel trailer. The trailer rims have a "0" off set.

I am also planning to switching to a 235/85 R16 E LT tire. What are some of the best brands of this size of tire? The Mich. Ribs are interesting but at $222. each they are out of my price range. Considering the BF Goodrich Commercial T/A at $139.00

Any comments or suggestions are appreciated.
