I'm glad they're working out for you, Chuck. Luckily I won't need tires right away, so I can wait and see how things go over time. How is the road noise level on trips?

They are louder than my PSS but not as bad as my previous r888's. A word of caution in that the hearing in my right ear is a bit off because of my surfer ear on that side.

I've seen the R888Rs fail myself on the track. Literally delaminated and came apart on two different P cars. Separated on the inside seam. I think there was in fact a bad batch, but Toyo won't admit it. At WGI with NASA last weekend there was a guy running them though and had no issues and liked them alot. I still see no reason to use them over NT01s, which last longer, do not squeal like stuck pigs, grip just as well, come in OEM sizes and never fail. If the R888Rs improve lap times I would consider them. If someone has some evidence of this then I am all ears. Also interested in their performance in the wet.

kumho 355 ACR tire is the only tire ill run in the rear

I have Toyo R888's as well...592/505 at the tire car. I haven't done burnouts, autocrosses, etc. Have been to the track once (3 passes) and done some spirited driving on the roads. IMO for the money, there isn't a better tire. They were recommended by a buddy who is running a similar car and does more autocrossing...gets 10K miles out of them.

And they've enabled me to **** off some more powerful cars with MPSS's .

Oooookay..... You care to explain why?

My car runs 164.47 in the 1/2 mile so whatever horsepower that is and the Bridgestone RE-11's I have on the car are great on the street. They quit making the fronts in our size. They aren't too bad in the rain if you get caught and fight hard for grip on the dry. I was going to give the R888R's a try next since I can't get the RE-11 fronts. Really disappointed since the RE-11's worked so well. I had the RE-50A's and they didn't hook up very well at this hp level.

I tried the Firestone Wide Oval's that someone asked about on my C5. Great touring tire but I think a modded C6Z would be too much for it when you really want to drive it close to the limit.

In edit, the RE-11's speed ratings is not a Y so keep your top speed in mind if you try this tire on the rear. I was running drag radials in the rear when i did the 164.47 mph and RE-50's up front.

I'll have to consider the kumho 355s.

It will handle that power wide open in second???

Also run MPSS 345's in the rear and I like them...I am geared with 3.90's 475whp...little to no problem with grip in first gear unless I am trying to spin them.

I'll second the Pirelli P-Zeros. I had the Michelin Pilot Sport run flats, upgraded to Michelin Pilot Super Sports (non run flats) they were much better ride, quieter, and better traction than run flats. Then, due to smoking close out deal on Pirellis last summer, I bought a full set front and rear because it was just too good of a deal to pass up. Best tires I've run. Hands down. PSS were great for the first 5000 miles or so, then they seemed to lose a lot of traction, even though they still had a ton a tread. Running 285/35-18 up front, and 355/30-19 in the rear - same size as the ACR. Have also heard great things about the Kumho ACR tires too.

Regardless, I highly recommend bumping up to 285 fronts, and 345 or 355 rear tires.

Try them and you will know why. Only made in two sizes. Tires meant specifically for the ACR and with the limited number of those cars tire rack cant keep the tire in stock... Outlawed in SCCA... Its like glue is on the tire. I can leave a corner hard in 2nd gear WOT. No other tire I've tried can handle that...

But hey just call me crazy and dont believe what I think. Its already hard enough to get the tire as it is. Last thing we need is more people buying them up.

Nice, I see you too are in Dallas.. Where did you pick yours up from..? I live over off the Tollway.. Frankford/Preston Rd...

Are yours 345's? currently running the Sport Cup II's and I am not a fan... Sticky as hell in the heat... But break loose on 3rd and are not real stable at speeds of 150+..... (ask me how I know)

no0one718

thanks for the input!

sorry for a dumb question, but i assume you run them on the front too?

TXGS507

Not a bad price @ $372 per tire... Just reached out to one of my Viper buds w his new ACR to inquire as to how he likes them

MTPZ06

Tires only come in 2 sizes:
295/25 - 19
355/30 - 19

Less than ideal for our cars.

What does a stuck pig sound like?

I have Pilot Super Sports on my Z06. It's a good all around tire. I've tracked my car in wet/dry and there's lots of grip. The 888"s weren't that great in the rain plus they were noisy.
I wouldn't bother with the 888R's unless you're taking the car to the track.

I'm running MPSS (295/345) on the highway and Hoosier R6's (295/345) on the track. on my 2nd set of MPSS/
