Haida SPRO HD937

OVERVIEW

The Haida SPRO HD937 is a performance and high performance, all season tire made for SUVs and passenger vehicles.

The tire offers excellent high speed performance. The tread pattern’s consistent surface contact boosts steering responsiveness and driving stability. This enables the tire to respond faster and precisely to the driver’s commands. The special shoulder pattern provides the necessary number of biting edges to guarantee a secure cornering and maneuvering capability. The durable compound and the asymmetric tread pattern enable the tire to securely handle the high speed performance. The durable compound prevents heat build-up along the tread ensuring the tire’s secure high speed performance during the drive.

The tire also promotes exceptional all season performance. The tread design, wide grooves, and durable compound ensure dry, wet, and winter weather traction. The tire is able to boost its grip on the road surface by increasing the number of biting edges. The durable compound keeps the rubber flexible in changing temperatures. The four center grooves prevent hydroplaning by dispersing water and slush from below the footprint. These grooves boost the wet weather traction. These elements secure the all season performance.

The Haida SPRO HD937 uses its special tread design to ensure the tire’s comfort levels. The special tread design and the sipping detail enable the tire to prevent sound wave formations as they channel airwaves through the footprint. Thanks to the tread, the tire offers a quiet and comfortable driving experience.

Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
