Thinking about putting these on my Z06. Pro's and Con's on them. What I'm looking for is a tire that hooks decently on the street, but can still corner great. I don't want a Drag Radial for the street use right now. I'll get some later when I get extra wheels. I was going to go with NT05 Nitto, but everybody I talk to says the R888R's are great tires. Wear isn't a huge deal breaker although I'd like to get as much life out of them as I can. Stickieness for hooking and cornering is mostly what I'm after.

Thanks.

How much power?

Not 100% sure right now as I haven't gotten it on a Dyno Yet. that will happen soon. We're estimating 530-540whp at the moment. My goal is 575-600+ WHP depending on another cam change. We're guessing the cam I have now will top out around the 550-560 mark, but we're speculating at the moment. Dyno session soon. He's getting his new one install next week.

I'm basing my tire selection off of the final WHP which should be 600 hopefully.

I will let you know my first-hand impressions in a few weeks. I'm having a Forgeline 19/19 setup built for me, and will be installing 295/30 and 345/30 R888Rs on my ZR1...which will also be ~600rw shortly as well.

Granted, by the time I get them it will be mid, late December and cold enough to not get a perfectly accurate assessment for street use.

Look forward to hearing others' responses on this thread.

NT-05s do not hook as well as M PSS. NT-05R will hook fine but doesn't corner really well (it's a DR). I have R888s and they hook quite well straight and in cornering although they lost some grip while sitting in storage for 6 months. They do need heat to really grip. They also whine like snow tires and will wear out fairly quickly in street driving. I use them for road course events and to drive to/from those events 100-400 miles each way. I will get R888Rs in stock sizes when the current tires need replacing.

I run PSS on the street and get ~ 25 K miles on them. They corner well, but not in the R888 category and grip reasonably well when warm.

I have MT ET SS in stock 19" size for straight line, but would recommend NT-05Rs instead as the MTs get unstable above 140MPH. For drag racing a narrower grippy tire will work better than the same tire in wider size as the contact patch will be the same size but longer/narrower in shape at a given inflation pressure. HCI ~ 600 rwhp here.

I just picked up a new pair of the NT05R's in a 345/30/19... LOVE EM!! They hook nicely and have good street manners, also pretty quiet...

Premiumspeed

I ran these for a few road racing events and liked them, but i just swapped to the NT01 road racing tires and like them more. There isn't a lot of difference in straight line traction (my Z makes ~480rwhp), but the Nitto's seemed to corner a little better and not get greasy after 4-5 laps.

They do require a healthy burnout to get sticky if you are going to drag race.

if you have 600+ rwhp, michelin pilot ss are like driving on ice. they are great for easy acceleration and normal driving. if you drive more aggressive I would consider something else.

MPSS’s haven’t been a Choice for me. Heard some horror stories of high speed wobbles. Had that happen before don’t want no part of that. When you say consdier something else. You have a suggestion. I’m probably going with the 888R’s. I really don’t want a DR as I wanna hit the twisties around Home. We have some decent roads I used to tear up on my GSXR. Drug knees around a ton of corners. Now I want to carve them in my Vette, but I also want a tire that hook decent enough to eat some cars on the straights from a roll or dig if I need to. Longevity would be nice but not a must as this is more of a weekend car. It will be driven to work off and on in the summer.

R888R or NT01. Both are a great tire. NT01 take more heat cycles (40 easily) and are good to the cords. After the circumferential grooves are worn off they become a racing slick for the last 2/32nds of tread (superb traction dry). They are also quiet(er) than R888R, less expensive and come in exactly our OEM sizes. R888R are initially a faster and stickier tire, but they heat cycle out faster and sing. I've seen two examples of the R888R delaminating due to overheating and have pictures if you want to see them. But I think the issue has been resolved by Toyo. This is all on a race track. One that has turns (what a Vette was built for). Lateral grip for both tires is great. R888R is a faster tire (initially) and better in the rain. NT01 last longer and simply work. Both work well for carving canyons and on the track (the kind with turns).

They are both also decent in a straight line, but are not drag radials like an NT05R.

NT05 are terrible. Nittos are terrible. MPSS are a great all around street tire. The wobble issue with MPSS happened years ago (2012) and has been rectified.

I've had NT05R's and now R888R's and love the 888R's. They hook much better than the NT05R's did without the floppy sidewall. I spin about 6 feet from a standing start with a little heat in them. Definitely will but them again

I have a set of brand new NT01's sitting in the basement after taking Mordeth's advice. I currently have MPSS in oem sizes for the last 2 years and although I like them, I'd like to use my power a little more efficiently. 544/487 SAE.

NT01 definitely the best tires out of mentioned above. It is a step better than R888.
I have 3 sets of rear in the garage. I would like to unload 1 pair of rear if you’re interested. Will sell for cheap

SilverNotch7

I assume the NT01 people are running 325/30ZR19?

8,000 miles and 12 track days on the 888R's. I have run them down to slicks and still have confidence in these tires. I'm not the fastest car on the track yet run 1:47 at Laguna Seca and 2:02 at Sonoma. Best tire for the money I have ever driven on. Once I get done with the spare set of Hoosiers I'm putting on a new set.

JimsCorvettes

I run R888R's on the track but would not recommend them for street use. They work very well for track use but I have another set of tires for street. I believe other street tires mentioned will give you better traction when cold than R888R's. When I say cold, anything cooler than coming in after a 25 minute track session passing all the Mustangs I can find.

I will add, the tread pattern suggest track use only.

And rain? UM, not so much.

Andrie

yes that’s the one I have for sale as well. Brand new pair for $600 plus shipping. Savings of over $200.

SPDKLZ1

Why are you selling?

Andrie

i bought too many. I have 3 pairs. Just want to rid of 1 pair.
