Good tires should easily be in the single digits on the road force machine. If not rotate them. I put some michelins on a rv and they were in the single digits, those big heavy wheels can make a mess if they don't balance out, vibrations in a rv can tear things up.

On my JBL which is sprung pretty soft, I had a vibration start around 80+mph, when I did some brake rotor work I had the rotors balanced, problem fixed.

I have a new Toyota truck with Bridgestone tires, they must be made with soft material, when it is cold they can flatspot easily, and the tread seems to squirm and will cause a shake until they warm up and round out.

Lower pressure might hide the problem but it is still there.


Food for thought.
