On reflection, kinda' have to check on that one--I just got a set of
replacement 7.50-20 bias ply 8-ply rating for the front of the old C60
that keep around for a seed tender. ('58 283, 4-sp/2-sp axle, 14-ft
grain bed and hoist). The rears are 8.25-20 and also still available.
I presume if look long and hard enough, most common sizes are still at
least obtainable if not on the shelves at the local discount tire store.
