Tire rotation pattern for fifth wheel
I've long since forgotten where I learned this, but the way I do it is:
finger tighten all of the lug nuts, use the tire iron to snug them down in a criss-cross pattern, torque them down in a criss-cross pattern. Since I have all OEM wheels, I use the torque setting in the owners manual. I'd follow Ray's suggestion for finding the torque setting.
