The tread pattern for the G149 RSA RH is "tuned" for longer wear on urban streets and highway driving, while the G150 HSA uses special compounds for high-scrub applications such as school buses and local pickup and delivery service.
The G150 HSA also features sidewall protector ribs that help resist sidewall damage from the sharp turns and curbs encountered in neighborhood driving.
Both all-position tires, available in 11R22.5 sizes in G and H load ratings, feature circumferential grooves and lateral blades that help displace water for driving on rain-soaked roads.
The tread footprint was modified for enhanced wear evenness and to help lower overall cost-per-mile.
