I've got 31x10.5 tires on my Truck. What should I keep them inflated to for normal city/highway driving??

Your tires will have a cold psi max on them, I usually keep mine 10-20% lower than the max, my stock size are 50psi max and I usually run them between 40-50psi cold. The higher the PSI the better the mileage but rougher ride, vice-verse for lower mpg/smoother ride.

Cool. Thanks!

On mine the manufacturer specs are 35 in the front 41 in the back, but I usually run them at about 45. Unless I'm towing then I pump them up to 60 front and 70 back

Yeah I'm at 45psi on mine 31x10.50s

We get a lot of snow here, so in the winter I usually drop them to about 28 for better traction. I don't take the highways in the winter.

How many psi should you run below max during warm weather? My 32x11.50x15's have a max of 50 (when cold) an im currently running 37ish
