FEATURES AND BENEFITS
OVERVIEW
The Bridgestone Alenza Sport A/S (BMW) is a touring， all season tire manufactured for passenger vehicles and SUVs. This model is an original equipment of select BMW vehicles.
The tire promotes great all weather traction. It utilizes the all season compound and the detailed tread pattern to improve the dry， wet and winter weather road gripping ability. The compound keeps the rubber flexibility in various temperatures while the tread elements create additional biting edges to grip onto the road surface. The four wide circumferential grooves prevent hydroplaning. They disperse water and slush from below the footprint， further enhancing the wet and winter weather road gripping capability.
The tread design improves the controllability. The ribbed tread design enables the tire to maintain its surface contact at all times， which enhances the steering responsiveness and the driving stability. In this manner， the steering becomes faster and more precise， while the structure is stabilized against the driving pressure. The detailed siping placement along the tread area helps shorten the braking distance. The sipes create friction between the tire and the road surface to upgrade the braking power. The better controllability and the decreased stopping distance work together to increase the driving safety levels and to enable the driver's constant control over the vehicle.
The Alenza Sport A/S (BMW) promotes high driving comfort levels. The tread design allows the tire's close surface contact throughout the drive. In this manner， the tire absorbs the shock of driving while the tires are in motion， minimizing the road vibrations felt in the vehicle's cabin. The tread design's detailed tread pattern， on the other hand， reduces the road noise levels. The tread design generates a special sound-cancelling frequency that manages to negate the soundwaves during the drive. As a result， the road and tread pattern noise are not heard by the passengers. The lowered road vibration and noise levels guarantee a quiet and comfortable driving experience.
This specific tire is marked with (*) as it is the original equipment of BMW vehicles.
