Title: 1970 XR-7 Cobra Jet tires
Post by: CCP on February 01, 2018, 11:21:13 AM

   Hi guys. Working on a 1970 XR-7 Cobra Jet convertible and need to order tires for it. My question is, what brand of tires came on this car as OEM?
 The Marti report says F-70x14 raised white letters, but does not specify brand. Would they be Goodyear or Firestone? I really didn't think Firestones were available, but not sure.
         
       Thanks, any help would be appreciated.      Pete.

Normally if not specified on the Marti report they would be Goodyear Polyglas.  Your build date will determine whether you need "no sized" or "sized" tires.

That would be a "no size" tire then.

This is an original spare tire from a second week of October Cougar Eliminator.
