The best tire pressure is that which keeps the tire from breaking off of the rim and rolling the mower on you when you go beyond the recommended slope angle of your mower.
I ordered one of these low pressure tire gauges recently just for the mower tires. Makes a difference with correct pressure in each tire. Gauges 2-20 psi http://www.miltonindustries.com/gauges/pencil-pressure/low-pressure-tire-gage.html
True, Max Tire pressure is printed on tire sidewalls. But running max is not recommended, like on my truck, tires say 45 psi Max, but inside drivers door is a decal stating my tires run at 35 psi Cold checking.
Once tires get hotter tire pressures increase, so running max cold, leaves no room for heat-expansion.
My Cycle tires run 36 psi cold.
My Zero 12 psi rear, 22 F
Etc, etc. IMO, whatever the Max psi says on tire sidewall, I would go less than that by about 10% or your best judgement.
