I am reaching out for Staggered Wheel & Tire help from someone who has done it.
I have a 2017 Challenger Scatpack 392 Shaker, 4 piston Brembo brakes and 100% stock suspension.
I been surfing the forums and read so much conflicting wheel/tire information that I can’t figure out what combination to use.
I am looking for bolt only combination without using spacers or cutting the inner fender liner. Here are the combinations that I am considering.

Combination 1: Front Wheel 20”x9.5” +15mm offset & 265/40R20 tire, Rear Wheel 20”x10.5” +25mm offset & 305/35R20.
Combination 2: Front Wheel 20”x9” +18mm offset & 255/40R20 tire, Rear Wheel 20”x10” +18mm offset & 295/35R20.
Combination 3: Front Wheel 20”x9” +18mm offset & 255/45R20 tire, Rear Wheel 20”x10” +18mm offset & 295/40R20.

Has anyone done any of the above combinations that can confirm what works with zero issues?

Any certain style of rim you are looking at?

Here's what I did:

Purchased Demon Replicas from Factory Reproductions: 20x9.5 +12 offset(fronts), 20x10.5 +22 offset(rears).

Tires: Nitto Nt555 G2, 275/40/20(fronts), 315/35/20(rears).

2017 Dodge Challenger Scat Pack, drop with H&R springs. No cutting or modifications needed. At stock height you will be fine also.

First everyone thanks for your help.
The wheels I want to purchase are from the following:
Stock Wheel Solutions or Factory Reproductions looking at Front Wheel 20”x9.5” +15mm offset & Rear Wheel 20”x10.5” +25mm offset
OEWheel looking at Front Wheel 20”x9” +18mm offset & 255/40R20 tire, Rear Wheel 20”x10” +18mm offset.

I really want to use the 305 on the rear as a bolt on wheel/tire swap without having to cut the inner liner or use spacers.

Just to muddy the water a bit with a combination you haven't listed.

Stock fronts with 275s and 11" rear wheels wearing 315 Nitto tires, no spacers and so very little cut from the bottom edge of the inner liner out back it's hard to imagine you could possibly have an problem with it despite your concern. I'm talking about using typical paper cutting scissors to take off just a half inch of curl. When gone no-one would even notice.

Any reason for sticking with the 255 out front? These cars are BIG and HEAVY. Ideally they could use more grip than you can fit under the car no matter where you end up when your final choice is purchased. A 275 will fit easily on the front and while still not perfect it's a step farther in the right direction.

My first choice is Combination 1: Front Wheel 20”x9.5” +15mm offset & 265/40R20 tire, Rear Wheel 20”x10.5” +25mm offset & 305/35R20. I just was trying to find out if this is bolt on with no cutting or other issues with using the Rear Wheel 20”x10.5” +25mm offset. The help has been greatly appreciated

I have those exact rear wheel specs on my 2016 SPS with Firestone 305/35-20 Indy 500's. They fit perfectly, no rubbing ever. Should have come that way from the factory.

Rocket Man, I requesting you confirm something I will say at the end of the post. We have something in common, your ride is the same as mine except I have a 2017 SPS and I work in space base rocket sensor applications. I listed 3 wheel/tire combination in my original post. Please confirm the 305/35 20 rear tires are mounted on 20 x 10.5 inch with +25 offset wheels. If you say yes, looks like I am ordering some wheels next week.

Yes, I have Factory Reproduction Hellcat wheels, 20x10.5 with +25 offset. I have Firestone Firehawk Indy 500 tires in 305-35/20 (highly recommended). No clearance issues and awesome traction compared to my original RSA 2's in 245-45/20. I still have the 245's on the front but may go to 275 on some 9.5 inch wheels next spring

I want to thank everyone for the assistant. Now all I have to do is pick which style from Stock Wheel Solutions or Factory Reproductions. You guys are awesome and special thanks to Rocketman. I am going with Combination 1: Front Wheel 20”x9.5” +15mm offset & 265/40R20 tire, Rear Wheel 20”x10.5” +25mm offset & 305/35R20. I might go with 275 up front as TA suggested.

Rocket Man, I was looking at all the Factory Reproduction wheels. My SPC currently has the factory FR70 wheel in Hyper Black. I feel Satin Black FR70 will look the best also since most of the back on the car is Satin. Thank you again. I wish there was a way to communicate on here via email.

I just yesterday installed my 20*10.5 with a 25mm offset with nitto 555g2s on my 2015 SRT 392 and for a few miles had a slight bit of rub on the plastic fender liner. Pic below. I ended up trimming off the area I could tell it was rubbing on about a 1 inch wide by 2 inch long strip and now now issues.

Just wanted to let you know you can go 315 without spacers or any kind of serious modification. The plastic was able to be trimmed with regular old scissors.

My wheels came from

factorystylewheels.com

More than 50% of the people who have mounted 315 have had problems and either had to use spacers or trim the inner wheel well. Obviously 305 are the max size that fit with no problems. All you have to do is read the threads to see the results. Also Slwkat, have you had any rear seat passengers yet? If not, keep the scissors handy :)

@Rocket Man

I have probably read just about every thread in here before picking my tire width.

Trimming some inner wheel well plastic isn't something I consider a problem for running 315s in the rear.

Rarely anyone in the rear seat but again for the little rubbing on that piece of plastic isn't a problem to me. And honestly I think it would have resolved itself with a little time.

Honestly the performance between 305 and 315s for my driving style was negligible I end up with 315s just to have that fat tire in the back.

Yeah I get it. I seriously considered 315's but I do occasionally have rear seat passengers and decided to play it safe. I do love the traction from the 305's as I am sure you do with the 315's.

Just wondering what you went with and how they worked out.
I just put on BFG G-Force C2-275-40-20X9 fronts--305-35-20X10 rears/Verde wheels-20 and 25 offsets. Rears are right against liner at the hump, ordered 3mm spacers so will try that before cutting. I have a '18 SPS.
