Track and Auto Cross season is upon us. :-)

Anyone running Michelin Pilot Sport Cup 2's on their .2 Spyder?

Comments? Like? Wear?

Anyone had theirs "Heat Cycled" or "Shaved" by Tire Rack before install?

Track season? I knew there was a reason I stay in the the Bay Area. I've been tracking since January. Lol

I can't comment on mpsc2 on a spyder, but I can tell you my experience on the GT3 vs nt01 on my spyder.

The mpsc2 grip a touch more than nt01 for the first 12 heat cycles (1.3G), after that they drop to nt01 grip level (1.2G). Whereas the nt01 stay fairly consistent throughout their life. I can't comment on wear since wear on a gt3 isn't the same as a spyder.

NT01 is still the best value R comp out there, imo.

Have them on my 987CR, but first track day is in May and till then I run the Michelin PS2. Hope they work fine, only road-legal alternative (want to get to trackday and back on the sport tires, then swap back to street tires) is Dunlop SportMaxx Race.

180 tw tire gives more/same grip than 100 tw tire? that's hugely impressive

These days you can't really rely on any manufacturer tread wear ratings, unfortunately. They pretty much mean nothing.

DeerHunter

They're sometimes (but not always*) accurate when comparing tires by the same manufacturer, since the numbers are self-determined. As you say, a useless exercise when comparing brands.

* The most amusing exceptions are when a manufacturer (I'm talking to you, Toyo, Hankook, Bridgestone, et al) arbitrarily changes the rating so that the otherwise unchanged tire is legal for a particular racing class.

orthojoe

Yup. The ratings are now skewed towards auto cross classes to give people an advantage.
