Default Nitto NT 01

Nitto doesn't make a 285, it's a 275, or move up to a 305 (Impossible to find at times), or a 315. Highly doubtful that a 315 will fit. Nitto NT-01 has a great reputation for wear and stick. As a DOT 100 tire, you could drive to the track with these tires.

Or, if money is no object, go to Hoosier R7. I was able to get a 255 on the front of my NB 993, and 295 on the rear. Hoosiers are in another dimension when it comes to stick. These tires should NOT be driven to the track.

thanks martin. Iíve driven on most of these. Looking for something to drive to and from the track. But asking more specifically to see what fits. I do like nt01 but 275 is a bit narrow for a 11 inch wheel and not sure 305 will clear. Wish they make 285/295

I have same wheels for track and love my Yokahama AD08 (cant remember the latest variant). Safe even if raining hard on way to track, great traction and long lasting with little degradation in performance.

i see they have 225/40/18 and 285/30/18 would be around $1070.
Are those the sizes youíre running?

My only thing is that we typically run a 285 on the stock sized 10Ē rear. So moving to 11Ē twist rear seems better to move up to 295 Not sure a 305 fires. But those would seem to match the wheel size better

You have a somewhat handmade car. You won't know if a 295 or 305 will fit until you try it.

I got 255s on the front of my 993 and 295s on the rear, Hoosier R7 tires. The car was lowered to RS ride height, with -3.5 degrees of camber on the front and -2.5 degrees on the rear and the fenders were rolled. Big tires were significantly more pleasing to run than smaller tires. Turn it was improved, and confidence inspired with wider tires in the rear.

NT-01 305s seem to get snapped up in the beginning of the year...so don't linger on these.

I had a thread discussing this same topic for my C4S.
https://rennlist.com/forums/993-foru...a-de-tire.html

I ended up going with 235/40f and 275/35r with RE-71Rís. You want more traction up front to avoid understeer from the 225ís, so 235 works well. For me, the reduction in rear width to 275 (from 285 stock) helped with minimize my unwanted understeer. Also, because my car is a C4S I needed to keep the f/r diameters similar. With a 235f, a 275r was the best match. I love the setup.

great thank you. 275 seems like it would be really stretched on a 11in wheel though. Maybe should of just bought different wheels. ****

While itís not like how the 285ís protrude from the wheel lips on 10ís, the 275ís are not really stretched. 275ís are designed for use on up to 11Ē widths, so youíre not out of spec.

but since youíre shopping for a 2S car, you could probably go with 285ís or wider without having to worry about keeping the f-r diameters as close as you do on a 4S.

+1. Running 275/35/18 on the exact rim fro years without any issues. I used NT01 and Federal RSR-RR. Just check the tire spec for rim width.

Any 993S will have more understeer than a non w/ the same wheel/tire and suspension setup due to the wider rear track. The best you can do is minimize this trait. Usually w/ more rear sway bar and/or more rear spring rate

Even a regular 993 profits greatly from using 8.5 or even 9 in front. Typically you want 245/35 on 8.5 and 285/30 x18 on 10. But unless you want to run R7 these sizes aren't generally available in road+track suitable tires.

RE71R is a great choice for a road +track capable tire but be aware that their line may be changing there used to be a 285/30 RE71R which was suitable for use on a 9.5 to 10.5 225/40 or 255/35 are the best height matches, 255/35 the best for reducing understeer but the hardest to fit and you need at least an 8.5 for it. Unfortunately it appears that Bridgestone may be eliminating this size from it's tire line.

Lots of 993 use 235/40 or 245/40(I don't see an RE71 in this size listed) w/ 275/35 on 8 or 8.5 front(8.5 preferred even for 225/40) these are both good matches for 275/35(Re71 in this size is spec'ed for 9 to 11)

For the best possible track performance and grip you will always want to use the widest possible wheel for which a tire is spec'ed, for most 275/35 x18 that is an 11

NT01 is another good choice 235/40 or 245/40(slightly better match for height) & 275/35 an alternative for the rear here is 315/30 which is slightly shorter than the 275 but also induces more understeer

Lastly shorter is better for the drive wheels, that's a good reason to use 285/30 or 265/35 for these

Very interested to hear what you think. I have 235/265 on now and am considering 275 or 285 when the rears wear out.

I think you'll like that setup. Interested to hear if you feel like the rears are outgripping the fronts. Have fun!
