Wow, you guys are diging up the past. Tractor hasn't been that clean in quite some time. Yes, tires are R1 ags size 12.4X16. I've seen a different size R1 on 790s with a two piece rim. I like these tires but they will do a number on soft turf. Fortunately, we don't yet have much genuine lawn.
Now that we've moved, I don't trailer the tractor nearly as much so I should be able to avoid the chain police /forums/images/graemlins/smile.gif
