Purchased a 2016 dodge ram 2500 turbo diesel laramie, new, returned the truck due to a vibration bad enough the seats, hood, rear bed shook. It was bad enough I had to slow down to have the shaking stop. Then when on the highway the only safe driving speeds where under 62 and over 80. Anything in between caused the truck to shake. So, the truck sat in my driveway, the only time I drove the truck was when I had to and even then, I would only drive it on the back roads due to the shaking. Truck as been back 4 times for over a total of 30 days to work on truck with no solution to the problem. Shaking starts at 62 MPH and up, 72 MPH being the worse.

The recommended pressure for front axle tires is 60 psi, with axle load rating of 5500 pounds. The recommended pressure for rear axle tires is 80 psi with axle rating of 6500 pounds. According to firestone, the manufacturer of the factory installed tires, the pressure required for even rear axle max load weight rating is 70 psi. For normal load of 3000 to even 5000 pounds on the rear axle, 50 psi is more than adequate according to firestone. At 50 psi a load range e tire can carry 2680 pounds, giving an axle capacity of 5360--well over the daily weight for most non-commercial drivers. Over inflated tires not only wear poorly, they are dangerous. Over inflation greatly reduces the tread patch that contacts the road surface, causes excessive and unnecessary bouncing, increases the risk of tire damage from pot holes, and basically provides for an unsatisfactory driving experience. I'm certain the engineers at ram are aware of these facts because in previous years they provided for both light and heavy service inflation. It is utterly unacceptable and grossly negligent for ram to recommend, and basically require, that owners operate their 7000 pound vehicles on tires inflated to carry over 13000 pounds. Ram is causing possibly millions, certainly hundreds of thousands of truck owners, to unwittingly endanger themselves and others on highways around the country with these dangerous tire inflation recommendations.
