After having the 2019 Redeye for 1.5 years and 2300 miles, I could not get a good hookup under 60mph on the stock Pirelli's all season tires. Had Nitto 555RII 315 35 R20 installed on the rear. Not only greatly improved performance but think the rear profile looks better too. Have not yet driven in the rain. Traction improved, no increased tread noise and vehicle dynamics not changed.

That Blue looks so good. And I know those stock tires provide no grip under 60mph.

How do they hook from a 20 roll

 

[areuriding]

Is it me or does the tire look like it's leaning inward??

Only did several 40mph rolls and it was like a totally new vehicle. Wish I had done this sooner.....

I thought the same but is was the angle of the camera and how the Splash Guard was framed that made the tire looking like it was leaning inward.

Good tire. Have them on the Trackhawk. Almost as sticky as the Nt05r but much better in rain

They do put a lot of negative camber on the rear wheels of these... supposed to help them turn better. As those rear tires wear, you will notice they wear more on the inside. Not a bad thing... just a thing.
So, you have the 3.09 gear... do you find 1st gear is pretty much useless?? I had it put in a 2016 (narrow) HC. Pretty much had to launch in 2nd gear to get it to hook.

Don’t let them put negative camber out back. The spec is -0.2 degrees (this is where you want it or close to zero) to - 1.5 degrees. Closer to -1.5 degrees you put wide tires, the less traction will be found. Don’t fall for more negative camber out back for better turning.

Turning and traction do not go hand in hand.

Slightly negative allows for a flat contact patch when under squat.

Interesting statement almost an oxymoron. Never seen one of these corner so well they have a power squat in a corner! I always pound it out of the corners and get plenty of comments which indicate not many keep up with it in that part of the course. Flat works for big wide tires on these cars. Different control arms with good bushings prohibit ANY deviation in the static settings, so compensation is not necessary and actually makes it worse. That negative camber in the rear only will prohibit traction and don’t help a bit on cornering. Since the rears do not turn, just follow what are we thinking happens in a corner back there?

Cornering is a front end activity. So if anyone is screwing around with their rear camber they also need to check and reset the MOST important component = TOE. Every time, because it will change. Otherwise we read about the left and right darting under power. Our cars just work better on a track and the drag strip with that rear end flat and nearly straight with upgraded bushings to tie it up and keep it solid to follow the front. Got plenty of experience, lap times, videos, and witnesses to be confident on this advice.

Didn’t think such an obvious statement needed clarification.

If you want maximum traction from a dig, you will lose cornering capabilities when moving towards a wider drag radial or slick in the rear and a skinnier tire up front. It’s a trade off of what you find acceptable.

Having high hp cars for decades, I open to learning new things, but seriously doubt I will on a rwd car.

We were talking camber and turning left and right.
I would not and don’t need any slicks or drag radials. For absolute sure if you have either and want acceleration FLAT ON THE PAVEMENT my friend. Camber should not even be in your vocabulary.

Lol people asking about the 3.09 and 40 rolls and comments about NT05s - camber away…..

 

[Lone Star Redeye]

Have only done a few 40mph rolls. Like a totally different car. I have the 3.09 axle and tires left Discount Tire at 34PSI. Read lowering the drag radials to 26-28PSI will further improve traction. Next on things to do......

 

[Beyerd84]

Running NT05s up front and NT555RIIs on the rear on my Hellcat and yeah, difference is night and day. Only downside is I'll probably only get a year out of them lol

 

[kidsixpack]

Tires look absolutely perfect!

Just a quick question about drag radials on these cars, as a soon to be cat owner. I've heard the differentials on these can be a cause for concern once we add more grip out back. So people add a diff brace, which voids the powertrain depending on the dealership and what not. I assume powertrain is not affected by adding a more grippy tire haha. I mean it seems like a no brainer that it wouldn't as we should be free to run any rubber we want. Just wondering if anyone has heard about a circumstance where somewhere put on some more grippy tires, blew the diff (or other damage) and then had the FCA try and say ohhh it's the owners fault for adding more grippy tires.

Good Question. While I went with a 315 vs the standard 305 tire, if you replace the stock OEM tire with another tire of the same size, FCA would not have any grounds to void warranty coverage. Further, I believe it is incumbent upon FCA to prove the modification caused the failure to avoid warranty coverage. The argument might become weaker if the 20" rims were replaced with 17" rims.....

Stopped in to talk with my dealer. Made a stop in the service department as well. The service manager was there and we chatted for a while, really cool guy who's not surprisingly a gear head and hellcat owner. He said anything that alters the computer in anyway will void the warranty. He also said the FCA will use anything they can to get out of warranty claims, not a surprise. Said as the service manager he doesn't care (even if FCA does) that I add a CAI (which some have said isnt all the useful on a redeye) or do drag radials. He did mention that IF I had something happen with DRs on the back that I should make sure to take them off BEFORE bringing the car in. He suggested 315s and laughed and said he has them on his car. But when a car comes in for warranty service, FCA (or SRT I think) ask for pictures documenting everything and if they see DRs on the car it could become an issue.
