Kim,
They'll be just fine for DE! If they have a wet skidpad, you'll be learning really quickly about car control, though.
When I used to do DEs with street rubber, I actually preferred tires biased toward worn than new. All of that fresh new rubber "moves" around and generates heat which, at best, you lose some stick, and at worse can cause chunking. This is why shaved tires stick better and (I've heared) last longer than full tread tires on the track.

Generally the group sponsoring the event has rules on minimum tire wear. 2/32, or 1/16 is probably getting very close to the minimum. As was posted above, you won't have to worry about tire squirm. I found out that when my SO2 tires got that low on tread...they were pretty loose, which may not be the best way to experience car control
Why not bite the bullet and experience your car at a whole new level with a set of brand new Kumhos? With 17" wheels, you can get a set of VictoRacers. If you have 18" wheels, you'll need the Ecsta V700s. You have enough time to look for a spare set of wheels, about $700 for a set of 7" and 9" X 17" Cup Wheels. These wheels will clear Big Red calipers if that is your concern.
You can drive these tires on the street, no problem. Although with a tread rating of 50, they won't last too long. A spare pair is a sweet deal.
Street tires like SO2s will get chewed up plenty fast on a track

Kim,
I think Martin has the best idea but a second would be to replace the tires. As these tires wear they lose a lot of grip even with visible tread. Go on and get some new tires and run them in over the next month or so before the event.
What if you wear the tire down to the cords the first day of the event and have to sit out the second or get a tow to get home. The most expensive track weekend is one you have to sit on the sideline because your car wasn't prepped 100%.
My $.02

Hey Kim - if you want to lug a set of track tires around, these may be a good find:

Darn I'll be away for that date. It's always more fun to track other Porsche's then any other car-good competition within the family : ). I will be signed up for July 27th(Sat) for group C advanced so if you should go say hello or vice versa. regards. Mike

I've been told by several of the more experienced drivers to avoid going to racing tires until I get a good deal of track time under my belt. Reasoning is that street tires lose traction more gradually and with more warning than do track tires.
thoughts?

Curtis- I think that statement rings true. It's always better to start with street tires since for most part it's driven everyday and you know it's handling characteristics and for first timers on the track having some familiarity ie tires makes it all more predictable. After a few lap sessions under your belt then gravitating towards race slicks is the next step. Regards. Mike

R compound tires, whether DOT or slicks, have sharper breakaway characteristics and require faster hands in order to correct and save the car. Also, since they have more grip, you are going faster.
For a novice, that means you have to push harder to get close to the edge, you are less likely to be able to recover if you start to go over the edge, and you will be going faster when you lose control - not a very pretty picture.
For an experienced driver, the sharper edge makes it easier to drive right at that edge, hence many experienced drivers actually like the feel of R/Slicks better.
