Re: Vintage Tire Question
 

Lynn is right.

Goodyear was advancing the tires down the line. Polyglas was superior to the Widetreads. The only widetreads that were made (for OEM applications) after April of '69 was for the Corvette. Our guess on the reason that the 'Vettes continued with those tires (F70-15 Wide Treads) is that the volumes of suspension tuning data had already been written and the radials were coming up, so why try to rewrite and redo the suspension for 2-3 years?

Rusty,
My new '69 RoadRunner came with Goodyear Polyglass RWLs. Great when dry but really dangerous when wet.

Re:'69 Shelbys- Up to about car 2074, most Shelbys were built with E70-15 tires until they started building them with the upgraded Boss302 spindles and bearings, which Ford determined were needed to handle the stress of F60-15 Polyglas tires. There's a bulletin asking dealers to swap tires on any car with F60s not built with the Boss spindles, for safety reasons. (Which was all for naught when they got fitted with G60's and L60's on deep dish Cragars shortly thereafter....)
