I have a Ford 1996 XL 4.9 with 31x10.50r15 nexen roadian II tires ,the especified say 35 PSI front / 41 PSI Rear for 235/75/r15

What tire pressure should I put ?

93F-150

put 35 in all of them and you'll be fine. bigger tires generally need less pressure

I already did but the tire look a little low , it is normal ?

93F-150

i think its normal for at least the front ones to look a little low since theres more weight on the front. if you want you could try put a little more in a see what it looks like

at the morning I put it 37/41 to see how works and feels good but a little hard on the back , so I will tried tomorrow 36 PSI in all the tires . looking at the sticker said the gross weight it is 6250 lbs that why I tought to put 42 in all the tires

fill em up to 40 PSI all the way around....call it a day

I run 40 PSI winter and 50 PSI summer 65 PSI max...perfect wear for 42K miles rotate every 5K with oil change.

Thanks for the comments !!! I will try by tomorrow at 40 If I feel the truck hard , just reduce to 37

I ride at 40 psi all year round, but I also have nitrogen so I don't have to keep adjusting pressures.
