Price Check Is this 4240 a good deal?

[Kubota 2007]

Just a question???? Why are the rear tires "New"? a tractor with that many hours shouldn't have tire that looks like they just rolled out of a showroom. My new tractor has 7hrs and the tires look like they have been used. I just find it strange, tractor shows wear,seat looks like it has been used,but the rear tires show no use?
