These scans are from a Goodyear Jan. '72 Discontinued Tires sheet.

I believe these would be the rears. **** 7.75-15 POWER CUSHION (BL)

edit Actually I don't think these are the rear tires I was going to ask if they would've mixed polyester and nylon tires on the same car. Size and name are correct, just an earlier version "2 Ply nylon POWER CUSHION"

From KELSEY TIRE's website:
Quote:

All non-Corvette O.E. 775/15 applications were fitted with the Goodyear Power Cushion broad market tire. Although identical in design optics, this tire carried inflated dimensions resulting in a taller O.D. and narrower inflated section width and tread radius.

Construction:2-ply nylon tubeless.





I think the tire you'd be looking for is this nylon "Power Cushion broad market tire".

NOT the tire shown/listed below
