The Haida Racing HD921 is a performance and high performance, summer tire manufactured for passenger vehicles and SUVs. The tire has great summer weather traction and it grips the road well in dry and wet weather conditions. This is due to the special tread design that provides constant road contact. The tire’s four circumferential tread grooves disperse water from beneath the tire footprint and increase the wet weather traction and the hydroplaning resistance. The tire is not suited for winter weather performance.
