    Default 09 Silverado with 3" lift but i need to know rim and tire size?

    I lifted my 09 Silverado with a 3" rough country lift and i want 33s on 20s but i dont know what backspacing and offset i need to try and keep from cuttin on the truck.

    I would call RCX and ask them what they suggest for BS and Offset with that kit.

    Don't go wider than 8.5" - 9" and keep the offset around +18 or so. If you go with a 12.50, they will still probably rub.

    I'd go with 305/55/20 on stock (31mm) offset on an 8.5" to 9" rim

    The only problem with the stock offset is the likelihood of the wider tires rubbing the sway bar, etc. I would rather a little less offset and trim the fender if needed.

    Point taken, I don't have any experience with the NNBS, I just figured that since 305 fit on mine without issue the same would be true for the newer trucks.

    I'm not exactly sure why, but I've been told that strut spacers for these trucks cause the front tires to suck in as well. That could be part of the issue.
