Toyo R888R
I haven't seen anyone talk about this tire yet. Imagine they released this at SEMA?
Either way, who wants to be the guinea pig?

I'll be more interested in the tire when Toyo comes out with a better selection of sizes. According to the Tire Rack website the widest 18" tire is a 295 and in 19" a 305.

Tough to compare... NT01s were my first track tire after 400tw and then went to NT05s... so my butt is more comparing these to the 05s. Plus these are 295/30 vs 275/40. They were consistent throughout the day.
I'm curious how long they last vs NT01s.

I spoke to Toyo at length about these new tires last week. They seem to be a significant improvement over the very dated R888s but sizing is so limited. The Rs have better dry performance, where as the old ones have a better wet weather rating. Hopefully noise levels have been improved with the R's as well. That would make them more pleasant on the street for sure.
They told me that new sizes will be announced at the first of the year but couldn't elaborate. They said more sizes will continue to be released but what sizes, they would not say. They said that they due post "coming soon" sizes on their website as well.
I desperately need to replace my R888s, they are hammered, at the wear indicators, totally heat cycled out and quite hard. But I have to make any new tires last me 12-18 months so I'd really prefer to get the new style tires rather than the old thing. Going to wait it out till after the first of the year and make a decision then.

Wish I knew. My personal experience is that the NT01s survive heat cycling much better than the old 888s. OTOH,the parent company may have changed the compounds on one or both of these tires more recently.

I do remember the nt01 being sticky to the cords on the Miata but my R888's are like 300 tread wear tires now.

I'll elaborate on my initial impression comparing the 2 R888R and NT01. Keep in mind I was more newbish, thus slower on the NT01s.
NT01s (275/40) camber 2.1F/1.0R: I started fairly high in pressure, but kept coming down and ended up around 34-ish hot by the end. The wear mark was about 1/2 down the triangles, which was fairly even across the tire giving me close to 40 heat cycles (although last 2 days were a little slippery).
R888R (295/30) camber 2.5F/1.0R: First day I centered on about 38F/40R in hot pressure. 40/42 was slower. I don't really have intention to lower pressure much from my research and how they felt so far. The wear mark was about 1/4 down the triangle. They seemed very consistent during a 20min session.

Interesting discussion going on in my build thread pertaining to the NT01's, I quote my post over there, but basically I'm running 275/35/18 front and 305/30/19 rear NT01's on my C7 Z51 (OEM is 245/35/19 front and 285/30/20 rear). My lap times were actually better on the OEM Pilot Super Sport run flats which I thought was nuts, especially when my NT01's only had one prior weekend. The NT01's feel off SUPER fast and I've been using NT01's for the bast year and a half and through they were decent, but never really felt 100% on my C7.

Now to the more fun stuff, I just spent two days at Texas World Speedway which is basically my home track. With my ZL1 that was making ~175 more rwhp and had aero and suspension mods as well, I clocked a best time of around 2:03 and that was on Nitto NT01 tires. My C7 had a best time of around 2:00.xx on Nitto NT01 tires (275 front, 305 rear). My goal this weekend was to break the two minute mark. Well Saturday I was clocking 2:00.xx-2:02.xx consistently, however the back end felt loose. Sunday rolls around and now the tires can only go about three laps before they have zero grip in the turns and it feels like I'm driving on ice. I couldn't get better then 2:04.xx times. I reviewed some PDR video with an instructor and he gave me some pointers, my lines were better but the tires were toast, which is absolutely nuts because this was only the second weekend on the Nitto NT01's!!! They had about 400 track miles before they become complete garbage. Frustrated I started to pack up and decided for the last session of the day I'd throw the OEM Pilot Super Sport Run Flats on and give it a whirl. Well I clocked two 1:58.xx back-to-back! I was SUPER STOKED! Especially since I was on narrower (245/285 as opposed to 275/305) tires and they were much less sticky. I think the NT01's fall off fast where as the Pilot Super Sports are a little more consistent through their life cycle. If I had brand new NT01's I would have maybe been in the 1:56.xx range.
Here's the video of the two 1:58.xx runs. My C7 is bone stock with the exception of G-Loc R16 pads and DOT4 brake fluid.

Toyo RA-1s were notoriously good at being consistent down to the cords. NT01s were/are made by the same company.
Toyo 888s do not have that reputation and by most accounts tend to heat cycle out long before the rubber wears out (much like a Hoosier or Kumho V710 but without either of those tires' ultimate grip)
Could it be that NT01s now have the same (inferior) compound as the 888? I have asked the techies at Toyo but no reply.

I've never had an issue with R888s or NT-01s heat cycling out. But did have an issue with them getting greasy on hot days after about 10 min. Usually run out of rubber at ~30 heat cycles.

Fast forward to a couple weekends ago I used the NT01's again and on Saturday they were OK for the first two sessions, ~100 miles and two 20-25 minute sessions but then fell off fast.

I have used 1 set of r888 and 2 sets of nt01 tires. The R888 lost their grip at 50% tread. The nt01's have stayed consistent and get better when the tread is gone. If there are no changes in compound on the r888r, i won't try them.

I had never heard of NT01s heat cycling out until recently.
OTOH, given that 888s clearly do (while the previous Toyo RA-1 did not), I would be suspicious that the parent company just uses the one newer (and inferior) compound.
The Toyo RA-1 is still made for a few race series (Spec Miata is one of them I think). Anyone know how happy these guys are with the newer RA-1s? (Certainly Spec Miata, American Iron and Spec E30 series drivers hated the 888 enough to force Toyo back in to marketing the RA-1 but not sure if Toyo just changed the compound or still making the old compound)
