The Work Series line of tires has expanded with two tires in 19.5-inch sizes (225/70R and 245/70R) for Class 4-6 trucks and vans. The All-Steel Drive (ASD) tire is an open shoulder steel-belted drive tire, and the All Steel All Position (ASA) tire is an all-position, steel-belted tire with a less aggressive tread pattern. The tires will be available for order beginning in June. They are targeted toward the growing final mile marketplace, where smaller vehicles requiring 19.5-inch size tires are used. According to the company, the ASD and ASA tires can withstand punishment from constant curbing. They are engineered with an extra strip of rubber on the sidewall, called a curb bar, which helps ensure the integrity of the sidewall. The tires also will perform for vocational trucks such as utility vehicles and bucket trucks.
