Seeking tire advice...

[997S22]

Not advice but sharing experience - I ran the prior Sport Cups on 997S and 997 GT3 for 5+years. Both cars had significant negative camber for track use. Typically before trailing front camber -2 (when trailering ran around -3.5) would still roll tires under while cornering and wear outer edges. Before outer edges were destroyed I had tires flipped on wheels to balance out the wear. These tires are assymetrical with suggested mounting as in your picture. However the tread design is not particularly senstitive to mounting direction - especially on dry road/track. Look at the deep chevron tread design of a Hoosier or Pirelli Wet tire and you can envision how mounting backward will pump water under the tire in the wet - the Cup tread will not do that. I ran them until approaching the cords - little to no tread left. Obviously if you are driving the car to the track you need to be much more conservative. You need 2/32 or more tread left to negotiate even moderate rain on a drive to or from the track. If you are trailering or carry a 2nd set for street use that is not as big an issue. These tires are way less sensitive to heat cycles than Hoosiers, which are less sensitive than true slicks. With nearly 300 track days and 4 years of racing, in my experience heat cycles matter little for street tires. Hoosiers lose grip more noticeably with heat cycles, but for DE I run them almost to the cords - racing I use them 4-8 HCs than save for DE. Slicks I treat like Hoosiers but they are far more sensitive to HCs and fall off more noticeably. Used slicks are particularly bad until they warm up after a few laps or on cold or damp days - so require extra caution those first laps or a swap to newer tires. Hope this is of some help to you.
