Hi Dave,

Sorry, but your neighbor is correct.

There were quite a variety of rear tires through the years on the Stingrays.

The very very early 1968 Krates came with a color line “knobby” rear tire.
Later in ‘68 they were fitted with a “gripper” slik which had a shallow cross tread that continued into 1969.

I found a few photos showing the color line knobby and the color line gripper.

PS, the three round circles with dots on the sidewall of the Orange line knobby tells its a first quarter of 1968 date code.

Also the Fastbacks came with a narrow slik or gripper style depending on the model.

Thanks, Chris.
