Need new DE tires for a 997 C4S- I am running 19's now (Champion RS98) so I can go with new 19" rubber, The choices seem to be the Pilot sport cups, or the new Yokohama Advan AD08-R's, Bridgestone RE11 or get a second set of wheels in 18" and run the Nitto NT-01's or other 18" options.

Looking for some feedback, want to stay DOT street so I can drive to and from the track... Input appreciated.

The wether had been strange this year, did the first DE of the year yesterday in Colorado at PPIR, 70's and was a great day, the second day (today) is snowing, 6" predicted I opted to stay home.... Pic below from the office window...

I think the new AD08R is almost as fast as the NT01 and a much safer tire on the street than the NT01. The RE11 gots hot and greasy after a couple of laps so I would stay away from it.

Good to hear. I have a new set of AD08Rs on my 991S, ready for my first track day with this car in May. I was agonizing over the right tire to give good track grip and heat tolerance, without getting greasy, as well as being safe on the street in rain. A tall order.

Glad to hear you think they're almost on par with the Nitto NT01. I went through three sets of those on my M3 as a track-only tire and loved them.

Not an expert, but I think there is quite a bit of difference between AD08R and NT01. The AD08R is not a R compound tire. The R stands for "Revolution". The Yoko is great for drive to/back to track. I went Houston to NOLA, beat on the car for 2 days and drove home on them no problem. Did 7 weekends total before the rears were done and fronts still had tread left (Cayman 987.2). From others I've talked to running the Nittos they probably wouldn't last that long. Also I understand NT01 should be heat cycled and can be shaved like other R comp tires. So a key consideration if comparing AD08R and NT01 is whether you stay on street tires or make the move to Rs. For driving to/from track if more than a few miles, Yokos are probably the best bet. Just 2c worth!

I don't know about the RE-11s, but I've been happy with the RE-11As on my M3. I have not had them in the rain on the track, but they stand up well in the dry and I haven't felt them get greasy. Very consistent lap times during a 30 minute session and within about 1/2 second of NT-01s on my car at TWS. Being a street tire, they are considerably more durable than the NT-01s.

Rain on the street was fine.

The RE-11As are also considerably less expensive than the RE-11, though available in fewer sizes. I paid about $165 each for my RE-11As (245/40-17). For reference, I paid about $170 for Nitto NT-01s, 235/40-17 and I anticipate the RE-11As will last at least twice as long.

You don't need to heat cycle the Nittos. The Yokos should wear better as they have a wear rating of 180 vs the 100 for the Nittos. The Nittos should track better as they are softer. To and from the track the Yokos should be better.

Thanks for the comment on heat cycling for NT01. I have a set in my garage that I got online at a good price and have been head scratching on whether and how to initial heat cycle them. Thanks

To the NT01: They do not need heat cycling and dangerous in the rain (standing water). I almost spun out on my first new set while driving to the track and catching a shower. I slowed down from 70 to 50MPH but this was not enough ...

If you are not towing your vehicle / tires to the track, I suggest to get a second set of wheels that allow you to factor in the weather forecast. NT01 for dry conditions and another set with good street tires for rain and street duty.

Sticker Nittos will be REAL slippery for the first session out and will probably gain 10 or so psi so you need to take it easy first time out.
I would not recommend driving in the rain with them either.I ran a set for two seasons and
they're a good value for the dollar,i managed to get a lot of heat cycles out of them ... probably too many ... lol

This. NT-01s even on a damp track are a bit dicey, let alone a pouring rain.
