Original Spare Tire?
 

I was wondering if this is the original spare. It's a Dunlop and says Gold Seal "78" H78-15LT Belted Wide Tread on it. The original window sticker that I have says G-78-15-B On-Off road BB tires. I thought it was also interesting that my Blazer sold new for $4368 that seems pretty spendy for 1972. The tire was serviced at one time because the original owners name is written on it with a yellow grease pencil.

looks original. You probably should replace it if your going to use it though. The rubber is probably shot.

Don't know if Blazers were different than Jimmys. but I ordered mine with on & off the road tires. Came in with Plain old H 78X15 Goodyear snow tires, with real narrow rims you couldn't put a decient tire on. kicked myself for even oredering them, as they got junked a couple months later anyway. Not a lot to choose from back then, but about the best was an 11 X15 Armstrong Tru Trak. I paid 4700.00 for mine, but took a lot of bickering, so depending on options your price sounds about right.

My Dad bought a new Sierra Grande GMC in 72 for 4500. so price sounds correct and back then a 12x16.5 were huge tires on the 3/4 tons
