Looking at what i can see of that wheel, if it was me i would bite the bullet and buy all new steel wheels, studs, and nuts and then never ever let anyone use an air gun when putting tires on.
You know to go really light with the paint at the mating surfaces for the fasteners?Too much paint allows the fasteners to be tightened up, then the paint squeezes, and the fasteners are now loose.One of the things that came out of the government research into wheel-offs back in the 90's.Happy coaching!Buswarrior
