Default 4.75 Backspacing on a 37" tires

How bad am I going to rub? 37" Toyo M/Ts & 17" 4.75 bs Procomp 7069?

I was hell bent on the wheels. Do I have any options to rub less? Help me out guys.

I think we need more info.

What size tire is it = width? What lift do you have?

Wheel spacers fix everything. (almost)

They're going to be mounted tomorrow on my Stock JKUR suspension. I'm awaiting a RK 2.5 kit. Tires are 37x13.50R17. What is the most amound of backspacing you can run without hitting wheel on caliper?

First off your mounting these tires with zero lift and stock flares?

Secondly, yes they will rub like a mofo. I currently have 37x12.5 tires, 3.5" lift and 4.75" BS wheels and they rubbed bad on the lower control arms and sway bar. Fixed all this with Spydertrax 1.5" wheel spacers. I'm now at 3.25" BS

First I say stick them in the shed until your lift is on.

Second, you'll probably need some big bump stops with factory flares and 37s.

youll most likely need at least a 1.5'' wheel spacer and trim the pinch seem. i run the same tire size (toyo) be sure to check for rubbing on the upper spring perch when the tire is stuffed durring articulation

why not just get spacers? cheaper and can use your current wheels.
