Chevy Chassis is out of control

The subject of tire pressure is interesting.

I wonder who else has observed the same as me. That is....When I put in the proper tire pressure, my tires appear severely under-inflated.

Anyone else feel the same?

Took the fronts down to 55 and yes they do look low.

Yep! It just never looked right to me. To feel better about it, I add 5 more psi per tire than spec. If anyone wonders, I have used multiple gauges to make sure the reading is right. The tires still look a little low, but not as bad. With 30,000 miles, they have been wearing fairly evenly. The outer edges are not wearing faster which would otherwise be the case with under-inflated tires. The same goes for over-inflation, the inside is not wearing faster.

A little odd tire wear I do get is related to strong cross winds when driving the open plains for days at a time. The steering correction for so long a time "checks" the front tires on one side. If I get lucky, I get the reverse later to even out the tire wear. Nothing can be done about that except not to travel on those days.

With our first motor home (1983 Toyota/Mirage), cross winds were so bad on one trip across the Great Plains, we actually ruined the front tires during that trip. Upon returning home, I flipped one of the two tires on it's rim so the bad-wear was balanced, placed on the inside for better handling. That bought a few extra years.
