Wheel backspacing
Hey all,
So I found a set of Weld Outback 16x10 rims with 35x12.5x16 Cooper discoverer STT with 65% tread - $500 for the set!
I am stock height now (2002 Limited with 7.3) and will probably do the lift like YellowSled (Same rims as him! - love the look) Here is the thread:
https://www.ford-trucks.com/forums/8...ims-tires.html
This is the procomp 22210 springs up front and 5.5 tapered block in the rear.
The wheels have 3.5 backspacing - is that ok? I don't mind a little rubbing as I will never take her off-road - that is what my CJ7 with 1 tons and 38 Swampers is for! Stuffing a tire completely is really not going to happen....
What do you all think?

You will be more than fine. The acceptable backspace is around 4". Anymore and you'll be risking rubbing on the leafs.
Offset is calculated using + or - measurement (in mm) from the theoretical centerline of the wheel. Backspace is a direct measurement from the back lip of the rim to the mounting face.

Leveling your truck won't affect the backspace requirements of your wheels. Most, if not all, rims for trucks are listed with backspace numbers ie: 3", 4.5" etc... the bigger your backspace number the more the inner lip of your rim is going to get to your springs. Stick with a 4" backspace and you'll be fine.

Ok, so i did a search for threads on backspacing, and that's how I wound up here. However, I just realized I was in the Excursion forum, haha. Anyways, the brand I was recommended was Centerline, because it can handle excess weight. Does anyone know if this should work on the 99-04 trucks with leafs on the front?
