So you can tell if the sidewalls are folding over in hard cornering. Keep reducing pressure until you see them start to wear (or increase pressure if they wear right off).

I've never autoxed on RE92's before, but lots of people are running insane pressures, like high 40's & into the 50's. Maybe someone else can comment here?

I don't know about the winter, but I run 44F/41R at the others throughout the year. Where is the autocross at?

Autox is in Camden right across the Bridge from Philly. Check out the Tri-State forum for more details.

As for pressures you have to see what works for you. Use 50/48 f/r as a starting point and reduce pressures in 2psi increments from there (remember the pressures will go up after a run). When the car is handling to your liking and you're not chewing up the sidewalls you're about there. Don't spend too much time worrying about them anyways, spend your time concentrating on your driving. Talk to people and talk to the instructors (they will be announced at the beginning) and go on the novice walk through. Everyone is always more than happy to help out a new comer.

We can start with the pointers now:

But low, sell high.
Don't eat yellow snow.

As for helping out I'd love to but it will depend on which heat we are in. I can only really help out in my non-competition heat. If you're in my heat you'll have to ask another instructor (can't be worse than me, promise ).
