Default anyone siped their tires?

Title says it all.
What were the results? I thinking of doing it on a set of Yoko's I have on my Grand Prix for the winter.
If it woks there I may look at doing it on my vette, Discount tire claims a 200% increase in traction with 30% better tire wear.
Is noise the downside?

I had the rear tires siped on my pickup because of traction problems and it did help noticeably. However, I'm not sure it would be a good idea on performance tires/car.

Siping machines cut thousands of slits across the facing of the tire tread, from 5/32" to 11/32" deep. These slits create thousands of sharp, gripping edges to provide extra traction and safer braking under wet, icy, and snowy conditions. The slits are so thin, no loss of rubber occurs and the results are similar to studding your tires.

Dale, How long did you run the tires you had siped?
What are your reservations for doing it on a performance tire? Most racing org's ban siped tires because of the increased traction.
I'm really looking for the downside of this practice, if there are none why isn't done more often?

I siped my tires on the Expedition. Although I don't race that sled, it did seem to help.

I have no experience to confirm this, but I have read that the more sipes the tires have, the quieter they are on the road. It's the larger solid blocks of rubber in the tread that create more noise.

I'm guess b/c this is the 1st time i've heard of this. Larger tread blocks are better for dry traction and you are cutting them up, so they won't be as good in dry weather, but are probably better in wet weather.

I had it done years ago to my x-19 fiat,,, worked , did not effect tire life. This car was turboed, so it did have a little more power than stock....
