The tire dealer told me that these tires are non directional i.e. they can be mounted in any manner. However another person ... non dealer .. told me that the tires should be mounted in a certain manner as they are 2 are backward facing. I have checked the tires and their is no way that I can mount these tires in a manner that the outer treads area facing back on the left (passenger) side of my car. Can anyone confirm?
