Nitto Specs:
235/40/18 25.39"
245/40/18 25.55"
315/30/18 25.35"

Factory sizing is
Front 25.4"
Rear 25"

I will have to take another look at the manual to see what the requirements are on the AWD system but I can't imagine the 245/315 setup is going to affect it at all.

Will the Nitto 245/315 setup work with the stock rims and offset without rubbing? I was going to get MPSC 235/295 but would like to try the Nitto setup if it fits without problems.

I got rubbing at full lock with the Nitto when I ran it on the GT3. The only time I was at full lock was getting in and out of my spot in the paddock so it was a non issue for me.

I am about to pull the trigger on NT-01 245/40-18 and the 315/30-18 for my 996 C4S. In stock suspension do you think these will cause any problems what so ever even at full lock with a C4S? I will be using these on streets as well, and would'nt want to make the turning circle much wider.

Thanks

There is no detrimental effect of it rubbing at full lock. It just rubs the fender liner a bit. If you don't like that then you will have a larger turning radius.

Thanks, that is fine with me.

I put a set of Kumho Ecsta SPTs on my Turbo S 8,000 miles ago (standard Porsche sizes). I intended to try them at a DE. I drove 30 miles to the track, put in a day on the tires, was impressed, and am still driving on them. I JUST replaced the rear tires (cord beginning to show), and should probably get another 8,000 miles from the front ones. Two rear sets for every one front set, just as expected

You've gotta put air in these tires to get them to perform; also, break 'em in hard. Starting with 32 front and 40 rear (summer), after 20 minutes on the track they're at 40 and 48, with no heat damage. I've had them to 150 mph, and to 110 in the rain. Traction is excellent, they don't roll over, and the damn things are cheap!

Look into the Kumho XS.

I think I am going to go with the NT01's.

I got 40+ HC's with them on my GT3 driving pretty darn hard so these should fit the bill just nicely. I'll report back after the May DE.

I have mpsc and have been very happy with them. About to buy a new set. Have tracked them and drive daily with them.

I went with the Nitto NT-01. Used it this wknd. for the first time at M-O. In my C4S with stock suspension the 245 in the front and the 315 at the rear worked very well and no rubbing at full lock either. Is pretty decent in mild wetness too. For around $1k for a full set, highly recommended.

I just tried RE11s on the track this weekend, they flat out suck.

I need some new track tires and will be trying the NT-01's. My last set were Toyo 888's, noisy, otherwise I have no complaints. I have 37 HC on the front and think there are a few more left. Pretty good for a heavy car like mine.

What cold tire pressure do you recommend for the NT-01's? Hot temperature to shoot for?
