The quest for affordable eggmobile tires

So a while back, I bought a really old haywagon chassis online of Craigslist. The intent is to build an egg mobile on the chassis for one of my flocks next year. I took the rims off, and three of the tires were completely rotted out and needed to be replaced. I found a place in town that would mount tires on the rims - for $160 a piece. I almost messed my drawers. For that price I might as well just feed dollar bills to the goat herd.

A couple of weeks of searching, and I tried this place. Coincidentally, I drive past it everyday on my way to work. They deal primarily used tires, which is what I wanted. And between my limited english, and their limited Spanish, we were able to communicate enough to get things done.
Only one of the tire rims sealed the first time they tried. The other two gave them fits around the valve stems. They worked on it for a few days, and all three tire hold air fine now. Grand total w/ my grateful tip - $89 dollars. Compared to the $480 it would have cost at the other place, this was a much easier price to swallow.
The guys running this business are young, and they work hard. The business looks like it's run by 19-21 year olds, but as I mentioned before,they do great work, and have no shortage given the steady stream of customers. I wish them well for mine and their sake.
