I understand that they do, so I don't really need anyone to tell me that they actually do. I'm curious to know why.
Is it the tread pattern ? the tire compound ? both ?
It seems like only yesterday that I put Yokohama AVS100's on my car and now I have to switch back to my old wheels and tires before it snows on Friday. It would make me feel better about to understand why.
Thanks
Why do performance tires suck in the snow ?

All tire compounds have flexibility and optimum temperature ranges..........for performance tires it is 100F to 180F with the peak point occuring at 150-160F.
All season tires have peaks at 70-80-100F.
Snow ice tires need peaks at 32F.
When temperature gets more than 20-30F above the friction peak point wear is accelerated rapidily.
On the cold end each compound has a plasicization point below which there is a rapid loss of friction.......tires turn slick and hard.
Performance tires have this plasicization point at 45-55F! where A/S tires may get down to 35F and winter ice tires may be good down to 10F.

peformance tires suck in snow beacuse they werent made for it.
duh.
just like all-season tires suck at the race track
not the answer your looking for, but true. essentialy(like dennis says) the compunds and such are designed with certain parameters(heat, wear, etc)..typically, the more heat the compund will tolleratE(like a Pzero) the less flexibility and grip it has in cold temperatures(like Pzeros...I slide around a lot under 30 degrees...bleh.)

"Using silica instead of carbon black has opened up a new world of performance for tyre makers, as it not only gives improved fuel economy but also remains flexible at temperatures that would defeat standard compounds."
