"Fuel economy and long wear are ongoing concerns for many long-haul fleets, so long-haul tire tread patterns tend to be stiffer in order to promote fuel efficiency," he says. Tire tread patterns for regional-haul carriers are similar to long-haul in that they place a high emphasis on tread mileage and irregular wear, says Greg Kidd, sales engineer for Bridgestone Americas Tire Operations. "Regional trucks also are concerned with fuel economy, but it is not as great of a need as it is with the linehaul ap- plication due to increased stop and go," Kidd says. In vocations such as mixed service, where miles to removal and traction are more important, tread patterns will be deeper and more open for enhanced on- and off-road grip. The truck itself also plays a role in tire choice. If a truck is a 6x4 applica- tion, the tire selection may be different than with a 4x2 or 6x2 application due to the amount of torque applied. "Tire manufacturers normally indicate on their website which tires are best suited for the various applications," Walmsley says. Wheel position also dictates tread patterns. Since trailer tires are free- rolling and subject to less scrub from turning, they tend to have shallow rib- like designs. "Steer tires tend to be more rib-like in order to promote longer miles to re- VDO and RoadLog – Trademarks of the Continental Corporation • VDO RoadLog provides simple, automated compliance • Faster, easier inspections • Fast data transfer • Easy access to your data • Simple, easy installation • Compliance now and in the future • Backed by Continental – a global leader in ELD technology • No inspection hand-off needed – RoadLog fixed unit eliminates chances of dropping or damaging the device • Shares only the data required for compliance • Keeps your tablet or cellphone data private • Provides the security and accessibility of the cloud • Secure data transfers • Security of a standalone device • Instant log printout – looks like a traditional logbook chart • Thermal printer means no ink needed • No data transfer worries during inspections Simple Safe Secure Printable Available with no monthly fees www.vdoroadlog.com Simple.

"Drive tire tread designs tend to be deeper and more open to provide more traction." The tread's rubber compounding and design can enhance performance in specific applications when designed together, he says. "Limitations in a tire's tread pattern can be made up for in its tread com- pound, and vice versa," he says. "If a tire's tread compound cannot deliver required wet stopping distance perfor- mance, its tread pattern can be opti- mized to improve the way that water is evacuated from the tread area."
