Lug nut torque

Have a 2017 Columbus F377MB fifth wheel. ST235/85R/16 tires with 8 lugs.
Could someone tell me the torque for these wheels? thanks.

The lug torque is based on fastener thread size! Is your lugs 1/2" or 9/16? Youroo!!

MAYBE.... is there a sticker on your trailer above the wheel wells like mine that lists the torque right on it?
