At what pressure do you run your Sailun tires?

80 psi on a Sailun tire carrying about 2450 lbs. I have had one Sailun G-range tire for three towing seasons, about 24,000 miles total. The tread-wear looks even: no sign of underinflation.

I bought the one Sailun when one of my E-range tires blew out while on the road.

Note added Feb 19:
I looked at my tires today, and see a little more wear on the Sailun's outer tread, which is a sign of underflation. Therefore, I plan to up the pressure to 90 or 100 the next time out.
