We're running a set of 'Power Ranger' tires, 6.50/16's, on the '36 pickup.
They came on the truck when I bought it from a fellow in W. Virginia in 2007, over thirteen years ago.
Those buggers look like new still, really wear well. The guy that put them on the truck told me he bought them at a local farm supply store near Beckley.
Bias ply tires, they are a little rough riding starting out cold but settle down real fast! I really like them and they look 'period correct' for a '36 Ford PU
