I have a Craftsman Snowblower with 15 x 5.0 - 6 tubeless tires. It's getting old and has bead leak. Probably due to rust. Flat fixed didn't last. i read that you shouldn't put tubes in tubeless tires. I can't see why not. Not like it will cause tire to overheat at those high speeds. I know I'll probably never separate rim from axle, so I'll do it on the machine. Any thoughts. Thanks for any help.
