I'm running 35's w/5" backspacing and only rub slight to one side at full lock. I'm moving up to 37's and I'm figuring the same. Although ill be bumping up to 13.5 .. Currently have a 2.5" RK Max travel but gonna bump it up to 3.5" coils

Other things will affect rubbing besides just the bs of the wheel. bump stop length, shock travel, and coil height will all affect the way your axle moves (shifts) so there is no one real fits all answer to your question. If you wheel hard with lots of articulation you are going to want to run around a 3.25" bs wheel. 4.5" will work on the pavement but expect to rub the frame and lower control arms pretty good on the extreme trails.

Thanks for all the input.
