Anyone have a good starting point for V710 pressures? I am getting my tires mounted tomorrow and have my first event this weekend on them, SE Divisionals at Gwinnet County Fairgrounds. I'm afraid I'll start to low in the front and tear up the outside edges. What kind of pressures is everyone running in the rear to get rotation? Any and all advice is greatly appreciated.

On asphalt, I've been using like 42psi in front and about 33psi in rear. However, if it's cold/nasty (I live in MN, and it actually snowed at our second autocross this year), the 33psi in the rear gives some pretty stupid oversteer. I try have run as low as like 28psi back there in foul weather (and will run the fronts at maybe 40).

I've only run one concrete event on them, and I ran about 45psi front and the usual 33psi rear. 45psi might be too low for concrete, but again I don't have a whole lot of data points

This is on an HS Cooper, though, not a Cooper S. So far, on mostly asphalt, I haven't gotten obnoxious wear.

Have fun mounting them I helped my tire guy get them on my wheels, and it was a <fill in your own explative here>
