It's time for a new set of shoes. I had 275/40r20 Nitto 555R on the back, they lasted about 8k miles. Have the original Pzero Summer tires on the front, currently have 13k miles on the car.

I have decided to go with 275/40 on the front and 305/35 with 10.5 x 20 replicas on the back, Firestone Firehawk Indy 500’s all the around. More than likely will use Mopar stage 1 springs on the back only.

Anyone have some pictures of the 10.5 x 20 wheel with 305’s on their Challenger?

Wanted to do everything (wheels and tires) at Discount tire but they don’t sell that tire. Looks like it will be cheaper to purchase the wheels from Discount and have Firestone mount them, Discount wanted $176 to mount and balance the 4 tires (that seems steep).

Once I pull the trigger will post some pictures. With a 35 in the rear I think lowing it is a must.

What do you mean Discount tire don't sell those tires. I just ordered the same exact setup as you last Friday. The sales guy called Firestone for pricing. I had them price match the rears at 240, Firestone told discount tire that they were 291 the first go around.

Tires and wheels are supposed to be here today.

I called and they told me it would have be purchased from a 3rd party and i would be better off purchasing from Firestone. Direct quote... I am in Houston, 275 fronts and 305 backs... $976.02 drive out... Wheels I would purchase from Discount.

Those look like ECSs, did you need spacers to fit? I have PKAD HR5 10.5s with 25 mm offset, Cont ECS 305/35/20 on rear of 2017 ChallengerHC.
I did not use Spacers. My rears are PKDesign HR5 10.5" Hellraisers with the same tires as you. I did not need to use any heat, but the inner fender well is slightly warped from exhaust towards the tire....no rubbing, but a very tight fit. I imagine I will at some point have to use heat to pull the inner away from the tire....

Looks good, do you have a side angle of the car? And have you lowered yours?
I used Eibach Pro's on all 4 corners to lower.

I’m putting that setup on my rear tomorrow. Any rubbing issues?

so you had to run a 1/8” spacer.

I am not sure it was mandatory. It was very close and I thought I heard a few random rubs without. So for peace of mind i put the spacers on. The wheel/tires still sit great at outer edge, and no issues of any kind with spacers on.
