The only trick to it, is to make sure it's cold tire presure. Don't drive the truck a round and then add the air. Let it set over night, then boost the tire presure while cold not exceeding the max on the side walls. I guess it's easier for us who have air compresser's opposed to those who have to drive to the station.

I love old russian gaz-66 with tire pressure managment system. it is so good to change tire pressure depending on road conditions and load.... Why there is no this system for small trucks?????

It's not a good idea to Exceed a tires Maximum sidewall Maximun Cold Inflation pressure number.
To do so, will put the tires design structure at risk in a number of ways, including impact damage, traction, handeling, ect, ect.
Operating a tire above the manufacturers recommended inflation pressure, puts extra stress on suspension components, like extra impact shock on wheel bearings, ball joints, wheel rims, shocks, ect & affects a vehicles handling, all for not much improvement in mpg.
So when we choose to make radical changes in our vehicles mechanical set up, we need to focus on ALL the parametes that'll be affected, not just one, like messing with trying to improve mpg.
Just some more thoughts to ponder.

Of course it's not, but most people don't run close to the max posted on the tire. Most light truck tire's are a round 44 pounds, people tend to run 32-36 on these tire's. Gas at 4.00 bucks a gallon should be an incentive to air up a little.

I booted mine up to 46psi this morning [my LT tire is rated fo 50psi] I had hoped for 23mpg on my last fillup, and didn't reach it. Launching a boat and spinning tires didn't help, I'm sure.

If traction is an issue with what your doing with your truck, increased tire presure will only make it worse. When launching your boat, you may want to go down in presure a little, then raise it for normal driving situations.

After reading the posts I looked closer and have the P size tires which have a max pressure at 35psi, so I dropped a few pounds out.

Dropped mine back down to 42psi today. 46psi was too harsh a ride and what I was going to gain in mpg was going to be offset by the extra wear and tear on my truck so I guess this is my happy medium.

I would take the position of splitting the difference between the rec pressure for the truck and the max for the tire. The car or truck pressure is meant for a good ride usually, while the max for the tire is for extreme use. Taking a tire up to the max pressure will reduce the contact patch with the road and hurt in the rain also.
