It will be close for a R/T. The SRT's have more room. My SRT - I run 20x10s (+20 offset) with a 275 tire and it is close. You may have to drop in a spacer. The suspension geometry is different on the R/Ts and SRTs up front.
Also, a 255 will work better than a 275 tire in your case. The tire is what will rub, not your rim. A +15 to +20 offset would be better.

I want to run a 275/40 square settup, and a bilstien b12 pro-kit. I am not opposed to running a spacer upfront if i have to, i could get an 7 or 8mm spacer.

Just remember you might have to roll the lip on your fenders. I believe 2015+ came pre rolled
Baseball bat and a heat gun, got it haha

Good choice on the Pro-kit. Can't wait to see the pics here once installed!

I would personally go with 18mm on the front and the 25mm on the rear. Especially if you want to run wider tires. I just bought wheels myself and went through all of the offset calcs. You can run 18 on the rear but it really pushes the wheel out. You need that on the front to clear the control arm. I went 9.5 on the front with 15mm and 10.5 on the rear with 25mm. Running 275 front and 305 on the rear.

I want to run 275s front and rear i can check and see if they have a +25mm that will fit the rear, i saw a guy that ran 20x11s front and rear that ran 305s front and rear with some spacers up front and some fender rolling, not sure i want to get that crazy. Also it was a scat pack so im not sure if there's a difference in shape.
