Offset: +18mm
Back Space: 5.71

Is this a normal backspace and offset for wheels i have a set of wheel spacers but im not sure i want to use them. I have a 2007 4 door rubi with a TF leveling kit.... so what im asking is if i will really need the spacers or will the wheels fit without them?

 

I'm thinking they're gonna sit in too far and may rub. What size tires are you gonna run? A lot of vendors for lifts will recommend 4.5"- 4.75" of backspacing. I'd give TF a call and ask them, partly since they make your leveling kit and partly because they sell spacers so they'll be able to help get you dialed in perfectly. Either that or PM them on here (they're in the Sponsoring Manufacturers and Vendors Forum).

I meant for the OP, I shoulda' quoted.
I think that 5.71" of B.S. may fit but when they turn, depending on the size of the tire, they'll probably rub at lock.

 

so what is the best BS to get 4.5?

 

It really depends on your lift and tire size but for the MOST part, 4.5" is the sweet spot that'll keep you from rubbing inside and keep most of the tread underneath the fenders. If you go with less B.S., the tires will stick out further and apply more torquing force on your axles and knuckles. If you don't wheel much, this can be ok (outside of legalities of having tread sticking out from the sides of your rig, and the look of course), but if you wheel it, there's a lot more stress and COULD lead to premature failure of components that would otherwise have been fine with a deeper B.S..
Anyhow, like I said before, I'd give TF a call since they make your leveling kit and their experience in making/selling spacers makes them SME's on the B.S. you need. They are most likely going to tell you 4.5"- 4.75" is best but with 1" -1.5" spacers, you should be able to run those wheels just fine (1.25" spacers, which are fairly common, would give you approximately 4.46" of B.S.).

What size tires are you running or looking at running?
