The Bridgestone B380 tire is an all season passenger tire. It is a run flat, self-supporting tire that was created for use with the Toyota Sienna minivan. These tires are designed to provide traction all year round and even in light snow will provide extended mobility with the ability to run flat until you can get to a service station or just to a safe place. The Bridgestone B380 tires feature a symmetric tread design with independent siped blocks. Made from an all season tread compound these tires will provide great traction on dry, wet and lightly snow covered roads. On the interior the tire features a twin steel belt structure that has been reinforced with a nylon layer. This allows the tread area to be more stable and with a rayon cord body the tires will be durable even while being driven flat.
