rough ride,any rear shocks replacements...

[cc322]

Depending on tire size I would air down a little. I have 315/70/17 and I only run about 25-30 psi bump the back up to tow, the drawback is fuel mileage suffers.

Heres some info I found may help you out
1) If you are running OEM size tires on your truck you need to follow the Cold air pressures listed on the "Safety Compliance Certification Label" located on the drivers B-pillar.
2) If you replace your tires with a size other than the OEM factory tires, then you need to use Load/Inflation tables to determine the proper cold inflation pressure to run in your tires to support the GAWR located on the "Safety Compliance Certification Label".
If you replace your tires with a tire that has less load capacity (ie replace "E" with "D" rated) you will have to lower the GAW & GVW you carry.
NEVER inflate your tires to more than the Cold Max Inflation pressure stamped on the sidewall of the tire.
NEVER Load the axles beyond the capacity of the Max Load rating of the tires as stamped on the sidewall of the tire.
Failure to follow these guidelines can result in premature tire failure, ill handling vehicle and potentially cause you to lose control of the vehicle.
The load table for LT285/70R17 is:
35 psi - 2105
40 psi - 2315
45 psi - 2510
50 psi - 2755
55 psi - 2890
60 psi - 3070
65 psi - 3195
70 psi - 3415
75 psi - 3525
80 psi - 3750

You will get hosed. Put a bunch of sandbags in there and it will calm down. Airbags or not, with the factory springs it will be tough...
I drove past Glamis to Ogilby and back today in an F-350. Pretty bumpy...

But I did stop at the beach store and get a T shirt and a 6 pack...
Lotsa water in the dunes. It must have poured out there. I saw exactly three cars and one Rhino. It was packed...
