I put on my winter tires today. For the first time, I noticed that the direction arrows on one of the tires point the wrong way: looking at the outside, the arrows on three tires point counterclockwise and on one point clockwise.
So I've put
- two counterclockwise ones correctly on the left side of the car,
- the clockwise one correctly on the front right, and
- one counterclockwise one incorrectly on the back right.
(More context: They were already on their own rims, having come to me that way when I bought the car used. I've used them for three winters, and may get two more winters out of them. This problem may have arisen when I brought one of the winter tires, loose, to a tire shop for repair this summer, so I might not have driven in this incorrect configuration yet. Each tire has arrows on both sides, I believe. My car is front-wheel drive.)
Do I need to get it re-mounted in the correct orientation? If so, why? If not, why not?
EDIT: They're Winterforce, which appears to be a Firestone model.
