I see, good thing, if you were changing tires on rims I would have to give you heck about it lol.
I also did heavy tire work, with proper tools, knowledge and a little muscle, Tires arent so bad! Keep up your good additude! I am glad to see you younger guys,learning, teaching and enjoying our hobbie. Buzz, get back out to the shop and fix something(Not break anything )
Well not to toot my own horn but, changing tires isn't a big deal to me. When I went to work with my dad I could change a skid steer tire in under 5 minutes easy. (not counting time to deflate and inflate once it was off of the machine)
