My 37 dick Cepeks were underflated from supplier as well. I put them back up to normal tire pressure

 

I run my 295/70R18 Trail Grapplers at 38 up front and 40 in the rear. I think that was the Nitto factory recommendation for the 14 Tundra. I'd imagine the 35s shouldn't be to far off from that....maybe 40 up front and 42 in the rear. I'd say try that and see how it rides and how the tires wear.

 

I had to look twice on my door sticker but my stock 285/55/20 bfgoodrich D rated ATs require 49 psi cold. I have 52 front 54 rear, little firm but fuel mileage seems a little more consistant with higher pressure.

 

I run 40 front and 36 rear unless I am loaded with some weight I will bump up the pressure a bit.
I run about 18 when off-road

 

I run exactly 40 all four.

 

250-280psi or so. I try to get the most MPG out of my vehicles.
