Need Some Advice

I have a 2012 Jeep Wrangler 4wd Sport with stock wheels and tires (225/75/16). I wanted to upgrade my current tires and wheels on the Wrangler and I need some advice. I want to put a 285/75/17 tire on without lifting the Jeep. Iíve heard different things regarding backspacing/offset numbers. So the current wheel Iím looking at is a 17x9 with -12 mm offset with the aforementioned tire. Can I make this work without a lift? What mods if any will I need to make (stubby bumper/leveling kit?)? If -12 mm is too little what do you recommend? Iíd like to keep the 285/75/17 tire but will go to a 285/70/17. I know this is wordy, but I donít want to invest a couple thousand dollars into tires and rims and get the incorrect specs. Thanks for any and all help and advice.

Stick with the 285/70 if you don't want to lift it .

Throw a cheap easy 2" budget boost or leveling kit on, and you can run the 285/75's

As for the new rims, play around here all you want https://tiresize.com/calculator/

Use the tire size calculator that Hoss gave you and then go here for fitment questions.

I currently have 285\75\R16 Duratracs. The wheels are procomp series 7069, 16x8 with 4.75" backspacing. A 17" setup shouldn't be too much larger.

No rub while turning at all. I had very minor rub on the factory fenders at full suspension flex but I solved that with flat fenders. No lift at all, however I do plan on doing one later on.

I used the two tools linked above when picking out my combo, super useful!
