The Bridgestone B381 steel belted radial is a Premium Passenger All-Season tire designed for family sedans. It was developed to enhance fuel economy while it provides quiet comfort and year-round traction, even in light snow.
On the outside, the B381 features a symmetric, independent, siped block tread design that uses an all-season tread compound to provide traction on dry, wet and light snow-covered roads. Internally, the B381 features twin steel belts to stabilize the tread area and a polyester cord body to help cushion the ride.
