on the repressing of tires
swoop223 is correct
even though you can technically do it, they will not stay on the hub. Back when cat had their own tirepress guy we tried it many times only to have it fail because the tires would start comming off the hub over time. Once the pressring on the tire has been expanded after the initial press it looses its holding integrity. We tried several methods of countering this effect by applying welds to the pressring on the old tire and anything else we could think of to reuse them but in the longrun they just would not stay on the hub, in some cases we even had the pressring on the tire break after repressing. Its a bad idea overall and imo a total waste of customers time and money.
Now bbforks idea of just welding the tire onto the hub at the seam outside the edge of the tire may work but that even requires more time grinding it down if you ever have to replace the tires, the heat from the welding affects the tire bonding on the outside of the tire and can cause premature bond separation, it imo is just another 'backyard' fix that could be avoided if the job is 'done right the first time'.


What you spend on trying to rig the old tires to work or even taking new tires and grinding them down you could invest in doing the 'right job' and just fix the OHG or the clearance issue in the door.
Like i said, i've been down this road before and its just not worth the risk. Saving the customer money? Not really.
