has anyone run any tests or have any subjective belief as to the differences between the Yoko, Michelin and pirelli tires for the 991 cups.
imsa series is yoko
WC is pirelli and pCA is pirelli
im going to guess 100% that those choices aint about 'best tire' though all are probably a great tire. its probably more about sponsorship, ability to support the series, come with trucks of inventory and tire machines so the series can function well...
and michelin which in europe is the spec tire, etc.

but putting aside the business sides of the equation, i wonder which tire is better? one faster than another? more durable than another? maybe less ultimate speed but holds 90% pace for far longer thus an endurance tire...
been thinking about gTA3 with the 991.2 ABS and if i got that route, unsure which tire makes sense.
michelin is about 600/set cheaper than pirelli.
pirelli will be the races thus easy to just buy/mount trackside.
yoko - lots of support from imsa teams, setup info, etc

thoughts?

Isn't it funny how Pirelli is now less expensive than Michelin? How times change...

Steve, you can't go wrong with any of them. You might find a few more cycles at or near the sweet spot with Yokohama and Pirelli, though...

Mich N2# (Fronts) and N2 (Rear) are faster qual tires vs. Pirelli DM and DH.

Longevity wise the Mich fall off its peak fast, plateaus for 15 ish laps then drops off bad. I'd say the Pirelli has a wider window for its peak, maybe a lower but longer plateau after that, and lasts longer overall (in DH form).

Only drove Yokos a couple times in the 997 so not a lot of solid impressions. What do people think of them?

As mentioned the Michelins are fastest out of box and fall off quick. The Pirelli and Yoko out of the box are similar with the Pirelli being just a hair better. After 2-3 heat cycles, the Yokos start falling off. The Pirellis seem to be consistent for more laps or heat cycles IF NOT OVERHEATED. Keep them hot about 28-29 PSI and your good. If they go over 30 PSI then they become very slick.

Yes, spot on regarding Pirelli hot pressures

Where do you see this?

I'm still seeing Pirelli Cup rears at nearly $150/tire more than the Michelins.

In Steve's original post

28-29 hot for pirelli DH slicks?

Would this be good for a gtb1 cayman S or cup only ?

I run 30 hot all around

FLA997

Hmmm...guess I read Steve's post differently. ;-)

if i typed pirellis less than michelin, i typed wrong. for sure michelins are 150/less per tire than pirelli. pirelli used to be cheaper. now michelin is some

Veloce Raptor

Your OP said Pirellis were cheaper, hence my comment

Any updates on this? In general curious how the new Michelins compare to the Pirellis. The Pirellis have gotten so expensive it's ridiculous. I have not run Michelins in awhile. I know the sizes are a little different. I'm more concerned with longevity than outright speed. Michelins used to have a reputation for being very fast but only good for 2 or 3 heat cycles. I have had good luck with Pirellis lasting a lot longer than that. Is this still the case? Any have recent direct experience?
