Default Tire pressure on new tires

I got a set of Nitto Terra Grapplers in 295/70r17 mounted on my truck and I am curious what tire pressure I should run them at. I had the shop start them at 40 psi but I'm pretty sure I am already seeing a drastic drop in mileage since I got them installed. I would rather have them higher since that should keep my mileage higher. They are good to 65 psi. Would it be a pretty rough ride to increase them to about 50-55 psi? I will be driving a 3000-mile trip starting next month and I want to optimize my mileage as much as possible before then.

does the drivers door have a tire pressure sticker on it ?

the 65 psi is a maximum amount allowed for that particular tire, truck fully loaded to the max

I think i would maybe go up to 45 psi & try it
then try increments of 2 psi

Good Luck

Yeah the sticker says 35 psi. I will bump it up to 45 tomorrow and just see how that feels.

While increasing the tire pressure will result in less rolling resistance and a slight increase in fuel economy, you will be paying for it on the other end in the form of new tires sooner. High pressure will wear the center of the tread faster. I would stick to the tire pressure on the door jam, maybe venture up a few psi from there, but thats all.

The door sticker pressures are for a nice cushy ride with the OEM tires for the average consumer - which is what caused all the Firestone tire failures on Fords back in the 90s. The tires were rated at 45psi but the door said 32psi resulting in under inflated tires, which run hotter and caused the tires to separate. When running non-OEM tires, the door sticker is virtually useless. The max tire pressure listed on the tire will give you the best fuel mileage, load carrying capacity and usually the best tire wear - you see more tires worn out on the outside edges due to under inflation than the center due to over inflation. I always run the sidewall pressure and get much better tire life than rated - I put 75,000 miles on my OEM Michelins and only replaced them for a more aggressive tire, not due to them being worn out. I have 43,000 miles with even wear on my Destination ATs which are rated at 50,000 miles and I have at least another 20,000 left in them. I also rotate every 10,000 miles. A cushy ride is what the suspension is for and you bought a truck, not a Cadillac.
