I just got a 2022 challenger rt. Like it. Best 60 time i get is a 4.9.

I notice i get a ton of spin when i put pedal to the medal. Im upset that the RT came with 245s on 8" wheels. I was hoping to keep the 8s on the front and go with 9s or 10.5s with 295s or 305s on the back. Nitto nt555 so i can take that speed im losing on the wheel spin.

Somthing tells me with better grip in the back and better throttle response i could be hitti g some great times. Like constant 4.8s 4.9s or even some 4.6 or 7s without messing with the factory tune. Just better traction and knowing how to use it.


Are my expectations too high for the RT?

Not sure about the 10.5' but you can go with 9" wheels and 275's with no modification.

Accelerator (foot) control is very important

Im doing the best foot control i can. There is just a natrual spin from the amount of torque to tire size and weight. Best thing i can do is improve grip to acess

Definitely want wider than that. Im sure itll handle just dont know if i need offsets or not.

Welcome to Challengertalk If you look at Reproduction wheels, you will see offsets that work. A 315 works for many, but often requires some trimming or massaging (with a rubber mallet) of the fender liner. People go to 305s for this reason. A 10.5" or 11" should work with correct offsets. IE:

Offset may differ slightly depending on manufacturer

Yep, stock tires are not considered “shoes”. More like "slippers"

These are just what im looking for. Wider wheels that dont look off innthe back. Id figure a 315 would be too much but a 305 or 295 will fit great and catch.

Yeah. I have no idea what dodge was thinking when they did that.

For sure the factory 245s on the R/T's are terrible! Although if you're running an automatic chances are you're also stuck with that pesky open differential which doesn't help (assuming it's a 5.7). When I had my R/T, I went for a set of demon replicas (275 up front and 305 in the back) with Atturos on them. While I don't exactly recommend those tires, the wheel setup and such did help a bit with handling and launches (as well as give it a meaner stance).

"pesky open differential"

Pesky? It's the Devil's spawn.

So if you don't mind a bit of poke, you might be able to get away with a 315/35ZR20 on a 20x11 on the rear. I'd try and find something with a lower offset than mine though. I went with a +22mm offset partly because that was the lowest offset I could get on the wheels I bought. Maybe a +15 or +10mm offset or be prepared to perform a little blunt force modification to the wheel well.

I like that setup. I have an 8 speed auto RT. I think i. Going to do with the 295s on the back. And keep my 245s on front. Cause. I think thoes 245s on front will handle just fine.

But once i put the. Good quality fat shoes on the back. I think i can get that car moving off the line. I wanna do a 2500 rpm launch and catch the ground and beat the stock 60 time just by changing the rears i know it can be done.

Don't know how much is different from 2016 to 2022 under the car. I run 245 up front on 8" & the back are 20x10 Offset +20 with 295/40R20 Tires.

That is the perfect set up for the rear but others have gone 305/40/20 with a +20 offset with no rubbing.

If you want to go a little wider, you can go with 20 x 11 with a +21 offset with 315/35/20 with no rubbing but the tire will exceed a little and you will need to heat and press the wheel well liner. Just a heads up

How are thoes 295s treating you on your launches?

Thanks, may consider it. Pretty happy with what I got for now anyway.

I don't really race mine. They are Pirelli p zero summer tires, car is 5.7 Hemi M6.
I will say that when I do give it hell it launches really well with maybe just a little chirp then hooks & goes.

Thanks. We love it too. It gets two reactions, thumbs up or middle finger. More thumbs up though.
