I changed the front tires on my Craftsman 22 horsepower 50’ cut riding tractor a few years ago. Let me just say this,it was a pain in the ass to get those new tires back on that rim! It took me over 2 hours to get both tires back on the rim and sealed tightly. I called my mechanic at Car-X and he said next time bring them up here and I will change them out for 20 bucks. I told him you have a deal my friend!
Those front tires are a real pain. I was going to put tubes in mine, but it was such a pain. I took them to the tire shop, and they did it a lot less time than it would have taken me. And I didn't end up with scraped knuckles.
I use a long bolt attached to a saw horse , It fastens the rim to the saw horse and acts as a pivot for my tire spoons . And a bar clamp to hold the sidewall down . Easier working standing up .
Just did this job yesterday... Got the back two bigger tires after some struggle.. pains me to say i gave up on the small front tires after running out of time. The bead kept slipping off the rim. Had to take them into the JD dealer to get the tires mounted. Maybe I'll have better luck next time... Should have used oil...
