Default Winter Tire Pressures - 07 Wrx Sti

Hi,

Just put some Pirelli 210 SottoZeros on my REX and have struggled with finding the right pressures for semi-stable handling. The factory pressure at 35f/29r makes the car bias slightly change on minor throttle lift off (even on a straight line). With more matched pressures the car felt better. Some fellas here in "the great white north" recommended 40f/35r.

Any WRX STI winter tire pressure advice?

Any you folks experienced driving with the Pirelli 210 SottoZeros?

Wish summer was back, so I can run my Potenza's again.

I run the same pressure as I do with the summer tires (39/36) and my now 3rd season wear shows that to be just about right - it's pretty much dead even from wall to wall.
