I bought a set of used Pirelli Sottozero on rims. There's no directional arrow on the tires and only a "outside" marking. The "outside" was installed on the outside of the rim so that's good.
However, the tires are not symmetrical now. On the inside of the tires, the "V" pattern is rotating forward on one side and backward on the other side. Is this right?
