Tread splice info and the Nitto issue

Actually, you do need to lift. They key phrase is DO NOT LIFT COMPLETELY.

When the rear tires start loosing traction while you are on throttle it means you have exceeded the limits of the friction circle. Slightly lifting will reduce the demand for longitudinal grip and allow for more lateral grip, this will permit the tires to regain traction. If the tires have started spinning, slightly lifting from the throttle will stop the spinning and also allow the tires to regain traction. However, lifting entirely and abruptly will transfer too much weight off the rear tires and cause them to loose even more traction. The key learning point is learning how much to lift and when to reapply the throttle. With DSC you don't need to bother with all this, this is why it teaches so many bad habits. I would turn off the nannies before becoming too quick.

agreed, we have a section called the carousel that is a tighening radius sweeping left. your in it for a while and can really feel the back mid corner to exit. you creep up to and past the limit and just a slight slight tad off the throttle and you gain back that couple degrees of slip angle and no drama at all. if i stayed in it completly i would just end up backwards, or posting saves like bigjae!

Sometimes maintaining is the way to go for some style points but adding more definitely doesn't help.

Discouraged to see this while toting up the tires for a track day tomorrow. Not significant as compared to other examples in the thread, but nevertheless. I thought for sure when I purchased these for the first time last August that the issue was resolved. Called Jim at Performance Tread -- he said it was the first he's heard of the issue in some time.

2 track days on these. 1013 production date. We'll see if it worsens tomorrow.

I'd try and call Nitto directly. I think the number is somewhere in this thread. But you're fine as is. Keep an eye on it and do not use if it starts to chunk around the splice.

Thanks. No more splice after track yesterday. Tires are really feeling good now 3 days in. Like em.

Yeah they are a great tire and as bigjae will beat you over the head with also a great value. They don't heat cycle out and get faster until you cord them. I think I will keep them as an hpde tire for a long time and just run full slicks for time trial stuff. The extra seconds isn't worth the extra expense all the time.

I got around 11 days out of my RS3s after rotating and flipping. I don't know if the NT-01s have that sort of life, so value tbd in my case. I'm just happy they feel good now. Really wasn't a fan over the first couple of events.

Thats disappointing. I though Nitto was aware of and hoped they were working towards fixing this issue.

For what they are, they will last a long time. Probably not as long as an RS3. But they tolerate lots of sliding and drifting which will destroy most r-comps pretty quickly.

They work pretty well on a damp track.

You can get about 8 days out of nt01s doing the same. Should out perform rs3 to start and get better once 3 days in.

I just picked ip a set of nt01's for this years track season. They say man date is "CEH3613". Hopefully no splicing on these. 1st track day first week of March.

Just inspect them closely for the first few days. All my splicing has happened early on in the set. Only 1 tire was bad enough to warrant replacement. Rest I just rotated around and as the tread wears the splice is gone.

8 days? I got 6 days on my first set and now am only going 4-5 days. Do they wear faster the faster you go? My lap time has dropped from the mid 2:10s to 1:57s and change on my home track (basically went from being in the lower half of slower times to being in the top 5-10 guys in terms of lap time). The unshaved RA1s are holding up great after 2 days.

[askjeeves]

Where does everyone recommend buying the nt01 from? I know discount tire has them, and I've seen performance tread mentioned. Any other options where I can make sure I get a newer manufactured date?

When you call BRP your home track, does it make you more of a track guy?

On a serious note, almost no one in SoCal gets more than 4-5 days on track tires. All that 8 to 12 track days happens up north, northEast, etc.

[OC3]

BTW, my replacement set of NT01's (date code: 3213) ran 4 track days with no splice.

Are you suggesting its temp related or we are all slow up here? Depends how much slip angle you generate, over the limit frequently will make them wear pretty quick.

You guys have more walls at your tracks so we can drive more FLAT OUT because if we go off our cars just get a little dusty. I think I'm only going to get 4 days out of my front NT01s this time around. I think the unshaven RA1s might get 6 days. Keep in mind that I still drive with all of the nannies ON so there's only limited slip angle for me.

It's the track that I have the most seat time on and the 13CW configuration is the standard that everyone down here seems to use to gauge how fast they are.

That's part of the problem, what's a front nt01! I rotate and flip them to every position until I get everything out of them, kinda like a date.
