well what tire size you running? 4.56's put 35's back in comparison to stock, so 4.30's would work well with 33's. i'm gonna be going with 4.88's soon, but i'll be on 37's by spring

Do you plan on going bigger in tire size anytime in the near or distant future? If you're going to stay at 35" and smaller then go with 4.56's. 36" and bigger go with 4.88's or lower if possible.
