Nitto NT01 Hot Pressures?
The Nitto NT01s seem pretty popular so I was wondering what hot pressures the rest of were running for track use.
I presently run mine at 39 lb hot.
Thanks.

I haven't used NT01s since 2010 but looking back thru my notes it looks like I usually set them a little lower than that, somewhere around 36-37 F, 34 R. For me, determining optimal pressures is more guess work and feel than any thing, I'm not very systematic about it. I tend to just start at a level someone has recommended and then maybe adjust a bit based on feel. The trouble is getting accurate pressures is hard. Ideally you'd do a couple really hard laps and then come quickly into the hot pits and have someone take the pressures and temps. In my case, by the time a session ends, I've done a cool down lap and am back in my stall its a little late to be getting accurate hot pressures.

Last year I ran my OE PZeros at 42/41 F/R hot. This was 255/40s on 9" rims. I got a lot of bad sidewall wear, which I could show you if I could figure out how to attach pictures! To me, this points to my pressures being a bit too low if anything. Of course, this kind of wear will be affected pretty strongly by the tire construction, and rim support. Nittos are more of a hard core track tire, so probably better than mine. I know you run 275/35s on 9.5" rims, so our tires are supported similarly by the rims.
My first track session of this year was on Goodyear F1s, 285/35 and 255/40, on 9.5" rims. It was at TMP, and I ran 44 hot front and back. Cold pressures were about 35/35. It felt pretty good, and the tires seemed to be wearing evenly across their whole surface. I'm going to try higher pressures at other tracks and see how it feels.
