What is it worth? 1966 Goodyear Blue Streak tire.
I'd quess you could get @ $200.00 for it without much trouble, people love those nice spares...too bad it was used a bit at some time. I have spent & gotten good money for just the plain old GOODYEAR POWER CUSHION white walls 6.95x14's on SBP steel rims with 4 1/2" rim width. I actually have a full set of 5 I'm getting ready to sell of these: 1 mounted spare never used + 4 very low mile ones on original rims straight from the factory off a '69 or '70. They are something unusual for show. KEEP IT!!!
