    I am running 275/35/19 ZII's on a 3500 pound Mustang.  It is in RTR, but I thought I would post here given the street tire knowledge in this section of the forums.  Anyway, I am wondering what sort of pressures people are running in the ZII's if anybody else is running them.  I went with 40f and 38r with what seemed liked mixed results.  Any thoughts would be appreciated.  

    Thanks,

    Brent

    On my 3200lb E46 325ci, with -2.5 camber in front, and on Dunlop Z1's, I run 39/35 psi front/rear.

    I use to run in the low 30s cause the tire temps (probed after skidpad) was showing real funky temps on the inside and lower brought mid and outer temps closer. Tried 40 and it was no longer funky and temp distribution was much more linear. Now Im settled at 40ft/38rr, 3050lb Evo on 255 ZIIs w/ 10" rim.

    38F and 31-33R on a 3260lb car (V6 Genesis Coupe R-Spec), 19x8F/8.5R, 245/40R19 all around, -2.1deg Front.

    We've tried higher rear pressures, but for us it was making the car less stable trying to get power down early on corner exit.

    Dave,

    Do you adjust to these pressures after each run?

    Are you running the 275/35/19?

    Yes, we go back to that pressure after each run and yes, 275/35/19.     We have tried other pressures to adjust balance and it hasn't seemed to make any difference.
