I purchased the WR G2 but one side looks like it is mounted facing the wrong direction. Has the installer made a mistake?
No. The tires are marked to advise the installer which shoulder should be facing outward. This marking can be found in the tread groove of the center rib. The traction and performance are dependent on the compounds found in different parts of the tread more than the tread design. This tire is not directional despite an appearance that may lead you to believe otherwise.
