I'm not too sure if you're aware of Greater Cleveland Tire, but I've bought two sets of F-2 tri ribs from them. The first pair in 2010, and another pair this past week. Thus far, they've not gone up in price, and their shipping remains reasonable considering how much dispatching goods has gone up over the past six years.
*Note, the price is for two tires!

As with everything, I'm guilty of ignoring the face and looking at the frame, so I didn't even notice how bad your tractor looked. I simply admired the frame and such without even lookin' at the grille since both eyes matched... I thought it was a rather handsome puller until you pointed out the ill-favored paint...
Thanks for the post and generous sized photos!
Cheers,
