Doing a little vehicle upkeep and got to wondering. The recommended tire pressure on the door post is 30 psi front and back. The Max recommended is 44 psi. Vehicle is 2001 Ranger supercab 4.0L 4X4 automatic. Tires are 245 75R 16 Goodyear Wrangler RT/S. I think running higher tire pressures should yield better mileage, probably ride rougher. Any downside to running 44 psi except for the ride?

Thanks for any info.
