As part of the GM pre-delivery inspection (PDI), the dealers are supposed to air down the tires and adjust to pressures shown on the tire label.

I took my H3 down the rockiest bumpiest road I could find down by the shoreline and I had no porblems. I don't have the adventure package and I haven't touched the psi. The ride seems bumpy if I'm the only one riding in the truck. When I drove down those roads with 3 passengers it was too much fun!

Buy two 50 lb. bags of sand and keep them in the rear cargo area!

That will keep things smooth!

Also, with time the suspension will loosen some.

Want to bounce, ride in a raised Jeep Wrangler on MI roads.

yea give it some time, and it is a truck so if your not use to a truck (small) then it may be too much for ya? the dealers do forget the tires at times it depends on the delarship.

Oh I forgot, ride in my 01 Aztek with tow package and air sus. and you will hit your head on a pothole. rides like a mad bull on concrete
