Tires: Directional Tires, directional tires, tires

Question
Sinlge directional tires. Is there such a thing? Well I think I may have these tires on my car. The tire treads only one direction. Is there a certain way of mounting these tires?

Answer
John,

Directional tires will have an arrow on the sidewall pointing in the direction of rotation.

BTW, asymmetrical tires will say:  "This side out" or words to that effect.

If neither of those things appears on the sidewall, then the tires are neither directional nor asymmetrical and they can not be mounted incorrectly (directionwise.)  Just be aware that there are many tires that may appear to be directional or asymmetrical and they only look that way.
