New to the site. Bought a 2001 Silverado 1500 HD a couple weeks ago and love the truck, but the ride is very rough. I know there are a lot of posts on here about tire pressure and hate to be bothersome, but the recommended tire pressure for my truck is 80 psi. I read other posts on how to tell if the pressure is right, but I would like to see if any one knows about where to start. This truck is my everyday driver and I am usually riding with an empty bed so 80psi is brutal. Is there any reason I wouldn't be able to drop the pressure down a bit besides tire wear? At what point would it be a safety issue? Thanks.
