Thanks. I just bought that tire from simpletire.com for $89. They dropship from their supplier, so I'll need to wait a couple of days to receive it. The tire looks very similar to what came with the tractor. If it's close enough, I'll probably run with just the one replacement. If there is a significant difference, I'll likely buy another, so they'll match. hopefully they are very close, so it won't mess with the four wheel drive timing.
