Fully loaded it weighs 16260# with us in it (5700 front - 10560 rear). The tire chart I have for our tires shows 80# as the lowest pressure. The weights for 80# would allow for about 7200# on the front axel and 13600# on the rear. Wanting to lower the pressure below 80# I called Goodyear to see if it was safe to do that. The person I talked to said going below the 80# would put too much pressure on the side walls of the tires and would probably make the tires wear unevenly. Does anyone else have any information on this subject????

You are right, 82#. I don't know where I got that 70#.

Thanks
