It's a tractor tire...the wheel is a 15" and about 7-8 inches wide. They are mounted on a home made doodlebug type tractor.
Tacoma Wheel...that rings a bell.... The last time I saw wheels like this was at the Street Rod Nationals in Tulsa/1976. EDIT *** Waitaminute!!...didn't the Wheelkids' dad own Tacoma Wheel at one time, or am I thinking of someone else? ***
Isn't that Wheelkids last name ? I think his Dad (Gary ?) used his last name on the wire wheels they sold and maybe more wheels too. Wheelkid should know. Don I just remembered, the company they have is Rally America and his name is Gary McLean. Maybe they can tell you something.
