What’s A Bias Tire? - Priority Tire
Bias tires are, as the name suggests, constructed with the plies on a bias (or a slant). This means that the plies are criss-crossed across the tire from one bead to the other, usually at a 35 to 40 degree angle to the center line.So what difference does this make? Well, for one thing, the tire is less flexible as a whole.
