Gingerman lap vid, NT01 initial impressions
Fun day at Gingerman yesterday. Just picked up the Harry's Lap Timer, which worked flawlessly other than being off pretty significantly on the straight speeds on some laps.
This was my first time out with NT01s after RS3s. Read multiple reports that they're a faster tire, but times yesterday were dead even with RS3s. As far as feel -- believe I prefer the RS3s. The NT01s feel like a softer sidewall, with more lean, body roll, especially through the fast sweeper section of the track (1:00-1:10 in the video). I was running ~36 psi hot. I know they're a noticeably wider tire than the RS3 in 275 width. Taller, softer sidewall as well? Gingerman typically has very reasonable early/late season rental rates. I rented earlier this spring and ran open track all day with 5 guys total. If you're in the Midwest and might be interested in something this fall/next spring, chime in here. Fun track!

Looks like an awesome day and you were tearing it up out there as usual interesting to hear about the NT01's, as I just ordered a set of AD08R's to be installed on Monday, so will see how that goes. Love to get back out there with you so keep the invites coming. Great track, great peeps, great times. Hopefully, cya out there before the year ends

I'm 3+ seconds quicker on NT-01s than AD-08s. Give them a chance, you need to drive them differently,and as mentioned, try 34lbs. That's what I run hot.
I have track envy, of having your own track day. Baller!! ;-) |

Thanks for the tip Larry. Sounds more baller than it was.. Didn't cost me or the others any more than a typical DE!

The NT01s are great tires. Like the others said, give them a chance. First time out when brand-new, they're greasy, wobbly and horrible. Then after a couple of sessions they get better, and then continue to get better and better until they cord. Just don't run them in the wet once the tread wears down. Interesting that so many people are running them 33-35 psi hot. I typically ran them at 38-39 psi hot. Thought this was the target pressure, given that we have relatively heavy cars. 38-39 worked well for me throughout three sets of NT01s, and gave me fairly even wear across the tread surface, but maybe if I had run them in the mid-30s they would have been even better. Although, again, if subjectively you felt that they were "soft" and rolled over a bit, the answer would be higher pressures to cure this, not lower, right? Was that an old GT350 out there with you? Must have been fantastically loud and stinky!

I tend to run my temps higher too--30 cold gives me about 38-39 hot. Anything lower feels like the side walls are too soft and roll over. I'm running BFG R1s now (and like them a lot) but you will get a lot more track days out of the NT01s.

Quick slightly off topic question....I need to drive home on NT01s for about 350 miles. What cold and hot PSI should I be driving them on the highway going 70-90mph?

Ok, I look forward to the NT01s getting better then! Wobbly is exactly how I would describe them. I guess I'll be experimenting with pressures, but yes, I was sensing too much roll so an increase makes sense. I'm not sure what model Mustang. Lots of loud and stinky older cars out on Friday -- Mustangs, Firebirds, Minis, a Scirocco. I admire those guys. Looks like nonstop work though. Quote:

Yeah, you need to scrub them in on the street first a day or two for new NT01s otherwise...its can be a wild ride. I wouldn't call it a heat cycle technically but...its heat cycling the tire and getting all the crap off the tread.
The car WILL roll a lot more because you have more grip given all else is equal. Have you fallen in love with the gentle coo'ing sounds they make? I love it that!

Really didn't feel like more body roll. Very focused on the tires. Sidewall just felt squishy, wobbly, etc. I'll experiment with pressures and get some more sessions on them and see what happens.

Bumping an old thread. I had my first day on NT01 at Lime Rock on Tuesday. I was previously running BFG Rivals. I had the NT01s heat cycled and did not scrub them in on the street. In the very first session, they were very wobbly and not confidence inspiring at all (as noted above), but to my dismay, I ran my fastest lap ever at LRP in my first session on the NT01s!
They got better as the day went on. In my second session I beat my first session time and put down even faster laps than the first session. It was very hot (low 90s) and very humid so I struggled with pressures most of the day, but they were great. I was aiming for 38 psi hot and that seemed to work ok, but after reading through some of these old threads maybe I should aim for 34-36 psi hot? I did notice the cool sound they make, almost like an airplane is flying overhead. It was a little distracting at first and took some getting used to but overall I thought they were great. They also make a very low pitched howling sound under hard cornering (for example, I heard it most going from the left hander into the right hander, which is a quick left to right transition). Is the howling normal? I did find that if I waited a second and turned in later in minimized the sound a bit, but that seemed slower. I realize I need to learn to drive on these coming from street tires but any advice is much appreciated! |

These tires do require a different driving pattern and do much better with a few degrees of slip angle and increased camber (compared to street tires) glad you had fun at LRP |

Kind of off-topic, but I may cave & get a track-only setup, instead of a set of streeties.
How are you guys transporting to the track. I have an E90 w/ the folding seats & tire totes. Good to go between trunk & back seat? I *refuse* to break out my trailer... Lol TIA & great review, OP.

In my E92, I fit 3 wheels in the back seat, one in the trunk, along with my tool bag, 2 jacks, folding chairs, cooler, helmet, camera bag etc. You can do it, you just have to get creative with packing. I also wash most of the brake dust off at the track before packing up. Just bring a small bucket and a brush along. Not sure if there is water at your track but there are two spigots at LRP. |
