60-something years ago, we were making bunches of extra-wide wheels for dirt track race cars using a cutting torch, an angle grinder, and a stick welder. Cut the "narrow" section off two Buick or Cadillac rims, torch the center out of one of them, and tack weld the two "wide" sides together. Then mount the wheel on a front spindle, and check for runout with a carpenter's square standing upright on a level floor. Do a little finish welding and slag grinding, and "off to the races!"
