NT01 vs R888R hot and cold

[papasmurf_m3]

So I am trying to decide on R888R or NT01. This is only to put more power down not for track purposes. That I would run camber plates anyways.

Sizes considering NT01 265/295 or 305 35 18 NT01 vs 265/305 35 18 R888R.

Here is my dilema. I know the R888R are a great tire so are the NT01. Both are 100 tw R compounds. But, the NT01 hook all the way down to the treads. Amazing tire but, the speed rating is only to 168mph or so. I think the R888R are much higher 1888 mph or so?

So I read r the R888R need to be warmed up then they hook. Is it true? Not sure how they hook as the wear but, I suspect nothing like the NT01.

Cold - I "think" the NT01 will hook better. From what what I know they don't need much heat in them to start hooking. The R888R I hear need to be up to temp like 160 degrees. On the street and 1/2 mile runs I doubt will ever see that unless I bring tire warmers.

Warm - Not sure if there is a difference in traction.

High speeds - Will they both be safe at speeds in the standing half mile to around 190 mph? Does it matter? Does anyone know?


I'm doing street rolls, 60-130 and a few 1/2 mile events. So I'm trying to decide which tires are better for me. Do the R888R hook better then NT01 warm? Are the R888R gonna be pretty bad when cold like 80-87 degrees tire temps on a cool day? Something tells me the NT01 will hook better in most conditions.

Does anyone have insight on these tires? Warm and Cold?

I will need to run mostly in colder temps. Just wont see more then 108 degrees on a cool day. Warm days they could get hotter. Just trying to worst case scenario in cool weather. Don't want to regret getting a tire that must be warmed to perform well.

Thank you!

R compound tire need to warm up and that's how the material behaves. Since you will be running them in cooler temperature, I suggest to look up the operating temperature in their official websites and choose the lower one?

I use r888r for track and it takes 1 to 2 lap at 90 deg F air temperature to bring the tires up to optimum temperature.

I don't have any drag racing experience but typically track day tires have stiffer sidewalls which sounds like it would be counter intuitive to what you would want for drag racing. Why not just bring a set of drag tires/wheels for the rear?

I’ve a set of 305 r888’s on my cobra. It has a conservative 505/496 at the tire. Given I live in a warmer climate you have to consider that, however, “cold” these tires do incredibly well to contain the power and just hook n go. I haven’t needed any level of aggressive heating up to get exceptional straight line grip and find it hard to spin them on accident. I don’t have nt01 experience.

I might be wrong, but I believe since Nitto and Toyo are under the same company umbrella the NT01 and R888R are the same compound. At least that used to be the case.

Ohh because I'm not doing digs just rolls 60-150 and occasional 1/2 mile so I need a decent speed rating. Drag radials great for launch and 1/4 don't that trust them at higher speeds. It's for safety.

Thank for your input Ed! I'll do that.

This helps. I was just assuming. Looking like I may. Red to go with NT01 because of size requirements with my rear height. Thank you 🙏

I've heard this too. I certainly hope they are the same performance that would make so happy.

But, from my experience with NT01 they hook to the cords practically not sure if R888R same? If so they are probably the same.

Something tells me they are not. Someone correct me if I'm wrong

Why not use autocross tires which can grip better when colder? Don't NT01s take a lot longer to warm up than RE71rs? Or SUR4Gs?

[F80Speed77]

The A052 has great longitudinal grip!

[papasmurf_m3]

What do you guys think about NT05 they are 140 tw they look sticky and people saying good things.

They come in 265 295 so I won't have issues with fitment back and forth with my current 666m street setup!

[avantix]

My buddy ran the R888R on track and even after being brought to temp did not perform well. He switched to NT01 for the next event and never looked back. Granted this is for track use and not drag racing. I actually just got back from the track a couple of hours ago and was running corded NT01s and they still had excellent grip, not as fast as mid life cycle for sure but definitely good pace, not many tires can do that.

[F80Speed77]

A052 is also Y rated so good for up to 186mph and has some beefy 18" fitments, I'd bet you could make the 315/30/18 work they are also known for working well at lower temperatures.

No, they are not the same compound. The NT01 and R888R behave very differently throughout their life.

My understanding is the the NT01 and have very similar carcasses, but the the NT01 shares its compound with the Toyo RA1 as well as the the two tier layered tread pattern albeit with much larger tread blocks.

[CanAutM3]

My experience with the R888R is that they offer excellent grip when new but fall off quickly with heat cycling. They also need more heat to grip. The NT01 offer less grip when new but maintain their grip better throughout their life, they also grip better when cold (I barely bother doing a warm up lap).

My take between the two: for a time attack I would use the fresh R888R (albeit there are much better options out there for ultimate grip), for HPDE events, I would use the NT01.

what power level are you putting out? are you currently losing traction on a 60 roll in 3rd? i'm using Michelin PS4S and I've no problems getting them to hook for 100-200 (60-130) runs if the roads the dry. i think you would have to be in the low 6's 60-130 to lose traction in 3rd gear roll

Not losing traction from 60 yet but not fully tuned yet still quite a bit more to go before it's dialed in.

Even 40 roll with good PSS it's like 50/50 if it's cold out and tires still cold it will spin, if warm it hooked when it was stock.

Better to over prepare then under prepared and just stuck with excuses in your head lol.

I am running the RE71R's right now on stage 2 e30 and will not slip on a 60 roll. I haven't put my custom e85 tune yet, but cant imagine those wouldn't do the trick either. The R888's will get you roughly 8-10k miles if driven normal and hard.

What size RE71? E85 is going to be whole new ball game in terms of power. I'd like to hear back once you test that.

I'm going to skip the noisy R888R for now and go with nitto Nt05. 265/295.

Good to know. I am a huge fan of NT01's for street based cars. My track Evo ended up on Hoosiers after NT01's.

OEM size replacements. 285/265. I am sure I will add some, but it cant be so much to render them useless going from the e30 tune now. My understanding is roughly 50 hp/tq roughly. I will let you know when I switch, but I am considering going 305/275 also.

[papasmurf_m3]

I hear guys doing really good and hooking up no rea problems with MP4S 265 295s I don't want issues running and ideally you want the narrowest tire that you can still hookup with.

I have a buddy who dropped from 295 MP4S to 285 MP4S to save weight and says it's fine.

I'm debating between nto5 and MP4S. I may give them a try tbh. See what the hype is all about.

Any update on this? I'm trying to decide between RE71R and MP4S
