From the repair methods I've checked out, most would use a hydrolic press to straighten the wheel, and a dial indicator to check for true.
These shops have a machine set up for that job.
At our machine shop, I'd be able to set up to use our press to straighten, then I'd have to mount to a lathe to check with the dial indicator. Probably have to go back and forth several times, before I got it straight. But still, I'm sure I'd do it for myself or a friend.
(I love fooling around in that machine shop on weekends with my own little projects)
I have a project sitting out back half finished right now. A nice heavy duty single axle work trailer, with electric brakes.
(I built 3 double axle trailers w/elec. brakes in the past and sold them... this one is for me.)
Before that I made some sweet hunting knives out of D2.
I still want to design a better mouse trap. Like a mini-claymore trip, or a guillotine.
But right now, I spend most of my time picking splinters outta my butt from sitting around pining for Elizabeth Hurley.
