Pressure in 20" tires on 1st Gen???

[jimmystilwell]

2003 SR5. Bought it with over 200,020 K miles. Runs like a top (previous owner was an obsessive-compulsive engineer; great guy). He put 20" wheels on it for some reason; I replaced the worn tires with Toyo P245/60R-20 Open Country ATIIs. I have no idea what pressure to put in 'em. I pulled 35 p.s.i. out my ass. Anyone have a more empirically-informed idea? Thanks for your thoughts.

Its 44 PSI max. Air them up to 44 for best fuel mileage, if it's too rough a ride air them down to 32-36. Max PSI is written on the side of all tires.
