Please help, what is the best tire pressure?

I run the same pressures as you. I weigh 178#.

I had a vibration from 55 mph -62 mph whether I was in 3rd, 4th, or 5th; I have an SM5. So, I set the pressures back up to 20 fronts and 30 rear and the vibration seems to have just about disappeared.

Anybody calibrate their Air Gages, I have 3 different gages that show 3 different readings,
So for the last 3 years i just stick with one and guess.?

Pencil type air gauges are unreliable. I use a Moroso dial type with a bleed off button.

The gage that came with my Spyder, Reads = 19
Brookstone Precision=15.5
Acme= 20,
I Only use the pencil type to scratch my back.
The Brookstone and Acme are bleed type.
