I picked up an older, used, 3pt, finish mower. I was handed two spare tubes and one new tire was mounted - it obviously didn’t hold air in the tubeless configuration. I was so focused on trying to seat the new tire that I didn’t notice the rest of the tires until I got it home. The other three tires are filled with a black gook. They won’t take air and they show the appearance of an under inflated tire.
I attempted to mow as it was configured. 10 minutes later I see that I have rolled a tire off the rim.
I pulled all four wheels off and plan to take the to a local small equipment dealer. (The same dealer that have gotten several quotes from - but have purchased very little out side of parts
)
I’m looking for suggestions: Do I get new wheels with tubes? New solid wheels? Do I ask them to remove the black gook and install tubes and remount? Is rolling the tire off the rim common?
