According to Steve McClellan, vice president of Goodyear commercial tire systems, 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 used on school buses and in local pickup and delivery service.
The G150 HSA also features sidewall protector ribs to resist damage from turns and curbing.
Both all-position tires, available in 11R22.5 sizes in G and H load ratings, feature circumferential grooves and lateral blades for water dispersion, and a tread compound designed to deliver even, long wear. (Tire Review/Akron)
