Hmmmmmm.......I never heard or seen this, I believe the Good Year Blue Streak "street tire" (not the Blue Streak racing tires) were only available in 14" and 15"
Keith! Years ago on Ebay, I found a Blue Streak Racing tire in 13"!! A for racing only tire with no threads. It is in mint NOS condition. But the tire is hard like a rock! The stamped label is still there;
Shipper; Goodyear, Akron, OH
Consignee; Carrol Shelby, Gardena, CA
I will get a picture when I get home from Norway!
Keith! Didn't your dad had a mint Goodyear Blue Streak tire in the trunk?
