Ron,
The lack of proper tire pressure (22 psi you reported) directly relates to your mileage. To get this conversation back on the original topic, how about getting back with us on the difference you may (or may not) have experienced now that your tires are up to proper pressure levels?
Appreciate if you would keep the conversation on the original topic please and thanks!
Feel free to start a new post on your mileage topic (in the appropriate forum) if you want to continue that discussion.
Best Regards,
Dan

Just returned from a 25-mile circuit of country and in-town driving. It has seem to have improved the ride. Why it should improve the ride over serious bumps I don't know. The need to replace the shocks has diminished. I hope. Now its the strange part, I had what I called a wiggle waggle, similar to a duck shaking water off its tail. It was frequent on the highway home from town and it has gone away. Sidestreet's with tar stip fillers and raised portions are also diminished. Happy with the change for now.

Also, didn't we determine some time back that those tires are pretty old? Old tires lose their elasticity even if they aren't dry rotted. Belts could be separating inside, wheel weights could have fallen off, etc. Make sure all your lug nuts are tight. You don't want the wiggle wiggle to result in a tire flying off.

Proper inflation will stiffen the sidewalls and stop the wiggles. When they are underinflated you get side to side motion as the sidewalls roll around.
You will also get additional spring effect from underinflated tires that is not damped by your shocks. Having them be properly stiff will help on bigger bumps lile you mentioned.
