Mine arrived today, so did the new 11” rims, unfortunately rims don’t color match worth a crap and are going back. Now waiting on different brand rim, so be next week for me now before I can review them against a 315 NT05R that are on my car now View attachment 17367 View attachment 17368 View attachment 17369
What brand and offset ? I have a set of fastco brass monkey replicas in 20X11 with a 25mm offset and color matches fantastic just sitting on my shelf .

Don’t know brand, ordered from tire rack. I have a 10.5” pair coming from FR now that are supposed to match. I’ve been looking for a used pair for weeks, wish I would have known, may be still interested in them?

What size is everyone running on the standard body Hellcats? Asking for a friend who is interested in the G2 fronts and R2 rears. On stock wheels to further clarify.

I have a standard body, but with Phillips Fender Flares. I have 11.5 × 20 Triumph wheels on rear with 335 / 30 / 20

Thanks. Trying to help a buddy out. He's wondering what would be the best size to go with on his factory wheels with respect to the rears. Curious if he should be doing 275/40 front and 305/35 rear.... that is if his factory wheels will take a 305??

From everything I've read so far, you can't put a 305 on the factory 9.5" wheel which is why everyone is getting a 10.5" wheel. Running the 275/40 in the front on the factory wheel and the 305/35 on the wider wheel in the rear doesn't seem to be a problem either.

I’d say they’re 90-95% you can’t tell unless you know. I’m happy with them

I run a 315 NT05R on a 10.5” Brass Monkey replica +25 on my 16 and their a perfect match fit and form. Trying the new NT555R2’s soon as another set of replicas arrive to test them against one another on the street.

No rubbing or nothing? I've got a 2016 as well and just ordered the 10.5 replicas. I was going to order the 305's. Its probably a dumb question but how much more actual contact patch does the 315 give over the 305? Just curious...

10mm, less then a 1/2”, but even 1/2” inches count especially talking rubbers

305 Nittos on back with 9.5 rims will run fine. They bulge a little and you don’t get the extra contact with a wider rim.

Some folks on here prob wanna beat me up for saying that lol, but it will work and look.. ok. Best is to go with 10.5’s or 11 rims on back NB HC

I wouldn't go that far but running a 305 on a 9.5 rim isn't smart or safe. Reason why credible tire shops won't install it. Can it work? Sure. However wouldn't want to find out different at 80mph on the highway.

Thank you all for your input. I was more speaking as a realistic/performance stand point. My own opinion is that I do not believe there would be a safety issue on the stock wheels. This might be like an apples to oranges comparison but I know a bunch of guys that run 35 X 12.5 on their factory Super Duty wheels which are only 8.5 wide. I would like to assume that if a 12.5 (closer to a 315) can go on an 8.5" wheel and tow around 12,000lbs without issue, it should be, well, okay. Another comparison is the Ram SRT-10. These trucks come from the factory with a 10" wide wheel with 305's. I can't imagine that a half inch less would be that high of a risk.

That’s a 555r 305 on a 9.5 stock rim. I ran it like that for about 6 months with plenty of spirited driving

Just got the new 555Rll delivered yesterday pulled old rears off and heading to get mounted & Balanced should be able to put some miles on it and report back later today 70 degrees today should be able to get some kind of baseline not expecting wild results but much better than stock dry traction at least.

Since no one seems to be able to match the matte vapor color I had my factory rears widened to 10.5 " Toyo
R888R in this pic, wore those out in 4000 miles , now running Nitto 555R

Where'd you get that widening work done? And how much? I just had a bad experience with the Factory Replica F77 5 spokes I bought (same exact design as yours on my RE). I got the 20 x 11's. Brought them new to the powder coater. Fresh out of box, pulled'm out right in the shop (boxes were mint). He powder coats, then mounts and balances. One was bent or machined wrong on pad, right out of the box. I am thinking of going with the HR5's when available, but I might consider your application if reasonable. QUALITY, not color, is my concern. After market is junk. Did you sacrifice a pair of factory rims to do that?

I've ran 305/35 555R on stock rim 16 HC Challenger for 3+ years, driving in FL rainstorms, 100+ mph many, many times. No problems whatsoever. Unbelievable difference compared to stock summer garbage Pirellis. 20200119_105803.jpg
