Default Hoosier/Kumho PSI ??

For those running autox tires, what PSI are you at? I'm on my first set of A3S04's, and am trying to find the right PSI. I've read some other posts that seem to have a pretty wide range (anything from 40 all around to 58 or 60!!)

Curious what you run F/R on the A3S04, A3S05, v700 or v710 tires?

Thanks!

I'm running the so4 @ 58 Fr & 50 Rear but I'm still adjusting them so I havn't found the sweet spot yet. It will also depend on the surface your running on, I run mostly on blacktop. I'm running 275's on all 4

Cold...After each run we bleed them back down.

Default 275 710s

I've been running around 35-6f 30-2r on 710s, bleading off pressure between runs. I base my pressures based on temp on the middle of the tire in the front w/ a radioshack non-contact thermometer... its worked really well for me, but I don't much know what I'm doing either
