Guys, when going from stock tire to larger tire with heavier load rating and your wondering what pressure to run here is a formula from a freind on crownvic.net

OT=Old Tire
NT=New tire
DS=Door sticker

OT max. load X (DS psi./OT max psi.) X (NT max psi/NT max load)= new tire pressures...
example: 1609 X (32/35) X (44/1709)=
1609 X (.9143) X (.0257)=
1609 X .0235 = 37.8 psi Front...

1609 X (35/35) X (44/1709)=
1609 X (1) X (.0257)=
1609 X .0257 = 41.3 psi Rear

...give it a try...PR...

here`s my set-up...

2125 X (35/44) X (50/3086) = NT pressure.
2125 X .80 X .02 = ...
1700 X .02 = 34 psi...

I think that will still be soft bc it`s below the OEM placard... so 34 will match load, but oem psi is mushy, so we`ll up it to 38 say...PR...
