Ok now for you pbkid. I basically looked at what Bart had on his set up to see what would fit on mine. Which if I am not mistaken or maybe he can chim in or do search for his chamber rims. I think is was 6x4.4 maybe??? So I basically just used the search function and looked at who was running what and also looked at thier pictures to see how much it stuck out and got my solution from there. If you can get them to be nice enough to try a few different combos then that will work as well. I just got lucky on the first try but it was a try on first to see if it work, even tho I had already paid so I could have gone different ways. My numbers I am running are in the above post, so look in my gallery and that is how much they stick out of wheel well. I would say maybe 1.5 inches maybe a little more. I am going dub route because even tho legal to stick out in Texas its not legal everywhere.
Lasly because i think i just wrote a novel there. I would go else where to find someone that does know. There are sites out there that should tell you and let you play with options to see what fits.
