I'm going to pick up a trailer that is missing 12 lug nuts and has two wheels/tires on the ground and two on the trailer. 7.00 x 15 tires, but I don't know if the rims are the originals. Do the three-piece wheels look remarkably different than one-piece wheels? I am dealing remotely with two females who have no knowledge or history and take terrible photos. I'm having new 10-ply tires shipped to the city, but don't know what to do about the wheels. I have to move it from the location and deal with it after. Anyone know the lug nut thread size? I'm trying to take as much with me as possible to get the drums off and repack wheel bearings, etc. before a 4-6 hour tow. Any knowledge from owners or those familiar with this trailer is greatly appreciated in advance!
