    I have an 89 with 5.7 auto. 2"+ lift. I have 32x11.50 15's. I went to discount tire. There is more then enough room for 33's. My only question is I have 3:08 gears. Will there be a problem other than not enough ass from a stop. Any one with any input?

    I guess it all depends on your long term goals, ive got 35s with 4.88s, if you want to go bigger than 35s dont make the same mistake i did but putting money into the factory 10 bolts, get new axles, 14b full floater out back, dana 60 up front. 3.73 were my stock ratio and they worked with the 35s. Go to the 4wheelparts website 4wheelparts
    and go to drivetrain i believe, they will have a chart of gear ratio to tire sizes. Happy hunting /forums/images/graemlins/thumb.gif

    Keep it out of OD and drive that wimp....

    I have 35's w/ 3.42's now, and never use OD. Someday the 4.56's will find their way under there.

    I hate the current set-up....

    I ran 3.08's and 33's for 1.5 years. I moved up to 3/4 ton and then 35's (now 37's). My freeway revs were great (1979 no od) I couldn't move off the line downhill with a small locomotive pushing me. It did work though. The lower first gear of a 700 might help too
