Weight one, and because they are tubeless tires and and took the split rims and welded the locking ring on them, drilled and tapped for a valve, and I need to do a lot more welding on them and also I don't see me getting the bead to seal on the rim.  It would be a lot easior to cut out the center cention of the rim, weld it inside a 15 inch wheel and throw on some other set of tires. It is the biggest hurdle I have so for and would love to be able to look in the driveway at something other than flat tires.  Also I can then sell my 14.00 to recover some of my loss.
