that's just to clear them legally, in the event you put it in the wall, and then try to come back and blame them. Running these in the rear with NT01's isn't going to be dangerous, you'll just give up a little rear grip, compared to what it could be. It's honestly no different than the DE Cup crew who are running RA1 rears, with NT01 fronts...RA1's don't grip as much as NT01's, and a a considerably different construction. None of them are flying off track, well, except for Clarke who is on Hoosiers..

I'll be a guinea pig and try them once I burn through my remaining RA1's. Nitto gets the point, we'll see a 35 aspect ratio.

Now am on my third set of 245/315 NT-01 for track. I have found that 36 psi (HOT) is the bast balance for overall grip and best tire wear. Start at 27 cold for first session, then adjust to 36 as soon as off the track. Yet to have a set heat cycle out, and I get 7-8 track days per set. Although I have never had issues with the 245/315 combo (no problem with ABS, PSM, etc.), Nitto making a higher aspect ratio 315 for the rear will be great. The NT-01 is a great track tire, and a real bargain compared to other options.

John,

What car are you using the NT01 tire setup with?

.1 GT3

Greek...both .1 and .2 GT3 use the same size tires...

GT3 is .8" larger overall rear diameter between front to rear for stock sizes 235/35/19 & 305/30/19.
GT3RS is .9" overall diameter in the rear for stock sizes 245/35/19 & 325/30/19

The 245/40/18 and 315/30/18 Nitto NT01 is the opposite as the front tire is .2" larger than the rear.

Since we wear the rear tread depth a lot quicker than the front this difference will change making the rears even small.

Will this work at the speeds and bumpy track we drive at with out upsetting ABS and PSM....who's going 1st?

The Greek

Yeah, I knew that, but I just wanted to make sure his setup wasn't a 996 GT3. Didnt know he was driving a .1....

deputydog95

I think everyone is way over thinking this... I'm going to order a set as soon as I have the need. They'll be fine.

mdrums

Nope just me in the over thinking department!

where are you guys getting your NT01's? I'm going to run the 245-40 18's and 315 30 18's on my .1 RS...

Discounttiredirect.com is as cheap as I've found. Their prices look to be a couple bucks higher than others until you realize they include shipping which actually then makes them better than the rest. < $1100 delivered including tax since I live in a state where they have a presence.

Ordered mine around 9am one morning and they were here next day.

Jamie_GT3

Ordered, will install when the wheels arrive from Florida!

Run them on my 997.1
Would have replied earlier, but was at Miller in Utah with Hooked on Driving this past weekend, on the full track. Finally wore the third set to the chords midway through the first day, then put on a brand new set for the rest of Saturday and all of Sunday. My car did six 30-minute sessions Saturday and seven on Sunday. As usual, the tires were solid and performed great. Still hope Nitto steps up with the 315 in a higher profile -- then the doubters will be appeased and we can end this debate.

ChrisF

Any guinea pigs run them on a .2 yet? Pretty sure the ABS systems are the same. I figure the switchover will pay for itself on the first set of tires and I love NT-01's.

mdrums

If they work on .1 they will work on .2 997's...since the overall diameters are the exact same with the stock tires.

Mvez

Not saying they won't work, but with a higher profile the car will handle a little better, and I won't have to re-align and CB my car for the considerably lower ride height. I've got enough tires to last another year, so hopefully they will be released by then.
