How much backspacing will i need

I will be getting 32x11.50x15 for my 02 edge. How much backspacing will I need for proper clearance? And yes, the tbars are cranked.

My '03 has 16s, I assume yours too, so I would stick to that size.
The wheels I am looking at have a BS of 3.75 for 15" and 4.5 for the 16" wheels.
Before I would buy the wheels I will try them on the truck first looking for contact with the caliper.
Try the tire on the truck first or have the company you are buying them from do it, that is if they want to sell them.
Maybe try a local company for a test fit then buy on line, what ever works.

As usual, "do not mount the tire on the wheels before trying the wheels on the vehicle first".

Sweet, thanks. Much appreciated.

Another thing... as you crank the T-Bars the truck goes up and the area between the wheel mtg point and the a-arms/shocks reduces, so my assumption is that as you lift you may need to reduce the BS.
RCD states their lift requires a max BS of 4", so the 3.75 BS on a 15 Chamber Wheel looks good for this lift.

BUT, BUT, I wanted the 16" rims with the 4.5" BS; I'm out of luck unless there is a 16" rim with 4" BS (that I like).
