Wasn't the brand like Eagle GT or something? Typing in www.gnttype.org into address bar now...Aww, it's down...

Sounds right to me, that's the size I currently have on my stock rims and my dad had them replaced for me when I got the car, he's the kind of person that would get the exact same size.

Mine came from the factory with Goodyear Eagles 215/65/15.

Original tires=Goodyear Eagle GT P215/65R15. Most were black wall.

Here's a shot of an original blackwall GN tire. The optional tire was outline white letter (OWL).

Wol

My friend still has the Goodyears with the white outline, I wasn't sure if they were OEM, so few had them.

RPO tire codes. Check your SPID label.
QYZ-black wall
QYH-outlined white letter

I've got about 100 SPID labels in my reference library and if I had to guess I would say about half of the GNs were ordered with the OWL tires. All the other models were black walls. I would say it is very rare to see the OWL on a non-GN.
