Michelin Cup2
stock sizing of 225/40/18 and 295/30/18 - @ $1310
R888 usually suck but saw hey came out with R888R (updated version)
and they come in 996 turbo sizing - @ $912
Yoko AD08R 225/40/18 and 285/30/18 - $1070.

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.

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.

Are those the sizes you’re running?
My only thing is that we typically run a 285 on the stock sized 10” rear. So moving to 11” 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-71R’s. You want more traction up front to avoid understeer from the 225’s, 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.

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

While it’s not like how the 285’s protrude from the wheel lips on 10’s, the 275’s are not really stretched. 275’s are designed for use on up to 11” widths, so you’re not out of spec.

+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

Ended up with 235/285 Re71r. I’ll see how the balance is at the track.
