Is anybody else as crazy as me?

Nope. Curious if it works though. I've heard of people doing this and making it more true, but it throws the balance off. How'd it do for you?
 
Tire "lathes" used to be found at some local tire shops and car service centers back in the day..they actually shaved off the high spots if one proved too far out of round to balance without using a pound of weights..they were popular at 4x4 tire stores back when most tires were bias ply,and the big ones were often eggs instead of round brand new!..
 
What's that thing on the block next to the jack pushing on the tie rod

Greg72 had that done to his swampers a few years ago.
 
Had that done myself years ago. Had some 35's cant remember brand but i watched him do it, it trued up the tires very well and saved a lot extra weight's for balancing. Plus the ran down the road quite well.
 
Yeah, that is a scissor jack on the axle tube. It has a gear head on the front, so it's good for small movements. The floor jack is just easier to lift with. This is done with engine power, which made me pretty nervous. 3 tires blocked, no rear driveshaft, 1 hub locked and a pry bar through the U-joint on the opposite side.

So far, it's been mostly a learning experience. One tire seemed to improve, going from 110/1000" to 85/1000" out of round. The other one I worked on was just malformed in all ways. The rim is like 10/1000" out, but the tire is 145/1000", plus wobbling side-to-side. It's really enlightening to see them spin - amazes me that it drives as well as it does.
 
There's a place here in town that shaves tires and balances them on the truck. They do a lot of work on semis. Back when I still had it, I took my 2000 Silverado there because I couldn't get the front end with 35's balanced worth a damn. Huge difference immediately.
