I was advised to fill my tires at 110 psi for all six tires.

Does this sound right?

Thanks in advance.

I think, according to the chart, 110 psi. But it just seems really high to me.

OK, rough numbers from your axle weights are 4000 lbs per tire.
From your chart:
For singles (front) you can support 4070 lbs per tire at 75 PSI
For duals (rear) you can support 8080 lbs per pair at 85 PSI

The MAXIMUM pressure for the tires is 110 PSI which is entirely too high for your load.
