<VV> Not finding new tires in 80's aspect ratio only 70's at Discount Tire.

[Ignacio Valdes]

Hi, Looking for new tires for my 1964 Coupe because mine are 12 years old.
Discount Tire is my local tire store. Online they don't seem to have
P185/80R13's only P185/70R13's. Is it worth finding and getting the 80's?
If so where can these be obtained? -- IV
