Urgent! Quick Wheel/Tire help - Good deal about to go by.

Please HELP -
Tomorrow I have an opportunity to pick up a variety of new tires and wheels for 40% off, and will not be able to test fit them, so I need to get it right. There is so much information on this site about tires and wheels, it can be overwhelming and I know there are many differing opinions out there, so I'm asking for some good advice so I don't make an expensive mistake.

I would like to put a set if 33/12.50/15s on my Jeep (Jeep Specs listed below) but don't know the right wheel size and BS to get so they don't rub. I've also considered 33/10.50/15s but will these be too narrow? Will 32/11.50/15s be too small? I want to keep the wheels tucked in as much as possible so I don't have to get new fender flares.

Currently I have a 99 TJ Sahara with 3in of lift (1 body / 2 coil spacer). The wheels and tires I currently have on it are 295/70/17 Toyo MTs on Raceline 17x8.5 (4.75BS). They rub the sway bar and the lower control arms. I've tried 285s (still rub) and 265s (too small). I'm planning to go to 15in rims (black steel) since I prefer this look anyway. I have a 33/12.50 ProComp MT on a 15x8 or 15x8.5 (4BS) (not certain width and can't find any identifying marks on the Rim) which I have mounted on the Jeep, and it clears the Sway bar by 0.5in and the lower control by 1.2in. The 15in wheel I have was a the spare when I bought the jeep, so I don't know the brand of wheel. I'm looking at the Duratracs / BFG KM2 / BFG ATs.

As always, thanks for the help!

Lay the wheel on its face, take a peace of whatever flat is it that you have to lay on the back of the wheel (not the tire) mesure the depth to the mounting surface on the inside. God, I hope you can see what I'm trying to say here.

Rokmen TT, Rokmen control arms, Novak NV241 cable shifter, JKS 1.25" BL + 1" MML.

Anybody can take advice if it doesn't interfere with their plan.

Necko, Thanks, I was able to get the backspacing measured, but more was wondering what wheel size and backspacing would ensure the 33/12.5/15s fit and did not rub.

You answered your own question, you'll need at most 4 in. BS, a lot of people go for 3.75.
