My book says 110-120 ft lbs, so I use 115ft lbs for my 2006 ST235/80R16 aluminum wheels.
If you have not removed your wheels since you took it to storage, the torque should be fine. But you won't know this unless you check, so it's a good habit to have. If any of them are not at the torque you like, then check every 50 to 200 miles. I towed new and used trailers professionally and most trailer wheels held their torque within a day of towing, except for one. That sucker wouldn't hold torque for nothing even after checking torque every 200 miles. I reported it when I got to the destination, but I doubt the moron who received it knew what I was talking about.
