Tire pressure ?

I purchased a set of Maxxis Ceros tires and I was trying to figure out what tire pressure I should be running especially running around on pavement. Below is a cut and paste from the Maxxis web site which lists pressure and load of 18/960. I’m not sure what the numbers mean exactly. My Outlander 1000 weights 816 pounds dry.

The guy I purchased the tires from put 6 pounds in them which I didn’t think was enough so I pumped them up to 10 pounds.

What do you guy recommend?

pressure/Load (psi/lbs)
Rear 26X11.00R12 6 26.6 10.7 18/960 12X8.0 23/32
Front 26X9.00R12 6 26.6 8.6 18/825 12X7.0 23/32
