The 1 ton rims have the extra width - 1" on the outside of the rim. 9,.00 will loose steering lock, should be alright with 235's, might even be able to turn the lock stops in a bit and improve the turning circle. used to run 1 ton rims when I trialed a series. wouldn't go for the 9.00's though too tall, 1 tons had a different transfer ratio I think.
