I've got a Metzeler front tire for my race bike, Laser model. It has this v-shaped chevron pattern on it and I'm wondering which direction it should be mounted? I know that you're supposed to go with the manufacturers' arrow for direction of rotation, but it doesn't look right to me. I thought the point in the "V" should face down when looking at the bike from head-on, but the arrow says to mount it so the "V" would be upside down. Could there have been a mistake from the factory? I bought the tire used so I really don't know, but I thought every bike I saw with a Laser front had the point in the V going in the direction of travel. Help!
