Anybody else find their HD truck rides better at full tire pressure without a load?
At least for the 2500 (3/4 ton), which has 5 link rear coil suspension instead of leaf springs?
This is the only truck I've owned with the rear suspension like this, and the only truck where full load tire pressure all the time rides better. With all the other 3/4 ton trucks I've owned, all which had conventional leaf springs, the truck rode like a dump truck empty if the tires were aired up all the way to full load carrying capacity. I used to have to air the tires up and down all the time.
Outside temp dropped from mid 80's to mid 40's for high temp in only a couple days, and the truck started bouncing and squirming. Tires were 8 psi below full load rating (full load rating 65 psi front, 80 psi rear). I aired them up and the truck rides and turns perfectly again.
This is convenient, but weird to me. I originally griped about Ram TPMS low pressure warnings, but now I don't need to find delete software.
Thoughts? Comments?
