I am wondering what is the biggest tire size I could use on my stock 16" 99 VX rims. I really like the Pro Comp Xterrain. Is there anything I could have trimmed or something to make the smallest ones fi? I was looking at this suspension lift also but didn't wanna do that if not needed due to the money factor http://www.pureisuzu.com/99-01_3_lift.htm are any of you familar with this and is it a good lift? Thanks for any help
