Glad you have a load chart for your tires. Did you find the chart online, or did it come with the tires?
The larger Hercules tires, being primarily tires for the trucking industry, doesn't publish a load/inflation chart for their tires, at least on the web. My trucker brother-in-law said they just put 100 psi or 110 psi in them and called it good. And as long as it would carry the max weight, the tire psi was never adjusted for the load weight.
Maximum inflation, which of course would give a fairly harsh ride, can be just as harmful as under inflation.
