Yes, we typically buy in sets of 3 (right sides + left rear). We have a few left fronts at different sizes. We run the same left front all day unless we want to try a different stagger or don't have time to clean it between classes.I’m coming from sprint kart racing to oval dirt, as for the reason of my new guy question. Why do a lot of people sell tires in sets of 3? I’m assuming one tire doesn’t do much work and doesn’t matter much?
