GR 70-15 GoodYear Steelguard
 

Would a Black Letter GoodYear Steelguard GR70x15 be a factory spare on Vettes or all RWL?
Also what of others using this tire, any factory equipped w/ Black Letter or used as spare?
No date code yet but single unused original...anyone need one and/or have any idea of value?

That is certainly an original tire for the '78 Camaro Z28.

Re: GR 70-15 GoodYear Steelgard
 

Thanks and '77 also '79 Z28's maybe too but like the 'Vettes, wouldn't all 5 be RWL?
Again no date yet but this one's an original BL as pic below.

Hoping some 'Vette guys can confirm but digging deeper, looks like Black Letter GR70 tires were standard w/ 73-77 'Vettes whether Firestone 500, 721's or G/Y Steelgards &amp; RWL's optional?[img]<<GRAEMLIN_URL>>/hmmm.gif[/img]

Thanks fellas!

----You are correct, Pete! Had blackwalls on both my 73 and 74 both of which I ordered. In 75 I bought a new 75 convert with every option from Jack Douglas. It was the first time I ever met Jack and the following year I moved from Ft. Liquerdale to Hinsdale and started working for Jack and Richard Buxbaum at Classic Motors. Some of the best years of my life, although now isn't too bad either,,,LOL!....Bill S

No steelgards after 77. 78 z28' s used goodyear polysteel tires with small letters. Also 78-up cars used 225-70's. G70's are 77 and down.

Again it's an original unused spare, anyone have an idea of a fair value and/or need one?
Were GR7015 BW Steelgards original on anything other than Vettes...F-cars etc all RWL?
Here's the Tire # below also decode I understand, anyone please feel free to add/correct.
