Back a few hundred years ago when I waz a kid, the old fords ran the tracks very well. Just drop the pressure down to 10 or 15 lbs and you could go for miles. But ya gota watch out for those steam engines.
I think Coker has the molds now, but I don't think they make them like they were made in the old days - they just don't last anymore. I never thought to look to see where these tires were made-just assumed they were made here.
