Goodyear Blue Streak, late '60's era

[1967Z28]

For sale, one used Goodyear Blue Streak racing tire, size 6.00/10.00 x 15, R-4 tread pattern. Same rear tire size as used by Corvette and Camaro at Daytona 24hr race in 1968. Tread in very acceptable shape but sidewall has some cracks and one area on inside has shaved tread a few inches long. Not sure if it was rubbing, done on purpose, or what. Can send pictures. Price is $100 plus shipping.

Thanks,
-Jon
