longhaulLong-haul steer

The 101ZL commercial tire is a long-haul steer tire that has been added to the U.S. Environmental Protection Agency’s SmartWay list of verified technologies for tires. The 101ZL will be available in October in four sizes: 295/75R22.5, 11R22.5, 11R24.5 and 285/75R24.5. The tires feature the company’s Zenvironment construction, which controls casing growth and reduces strain energy in the shoulder and bead areas. The tire has contact pressure equalizer sipes and stress equalizer ribs. Serpentine grooves add rigidity.

Heavy-duty starter

The 44MT heavy-duty starter creates 8.5 kilowatts at 12 volts. Its patented technologies include the Internal Magnetic Switch Solenoid, a one-wire design integrated inside the solenoid. The solenoid can withstand engine temperatures up to 120 degrees Celsius or 248 degrees Fahrenheit. The Clutch Over Planetary Gear Drive System slowly rotates the pinion until it is properly engaged to the ring gear before cranking. The Integrated Over Crank Protection eliminates the need for a vehicle wiring harness in a self-contained, one-wire design with no additional connections required. The Over Crank Protection is a built-in circuit breaker that protects the starter from thermal damage and automatically resets at safe operating temperatures. The 44MT will be available late this year.

aftermarketAftermarket air conditioners

Sleeping Well battery-powered auxiliary air-conditioning systems are sold as complete aftermarket installation kits that fit almost any commercial vehicle. The all-electric systems can cool a sleeper while the truck engine is turned off. They require no regular maintenance, the company says. Models include the wall-mounted high-capacity Arctic 2000 (Red Dot model No. R-1200-0p) for sleeper-equipped tractors and the roof-mounted OBLO (R-1205-0p) for straight trucks and other applications. Both units are CARB-compliant and U.S. EPA Smartway-approved. The Arctic 2000 provides up to 6,150 BTUs per hour of cooling and can maintain a comfortable temperature for 10 to 12 hours of typical use. The OBLO provides up to 3,250 BTUs per hour of cooling.

Drive-axle tire for LTL

The BDR-HT3 tread is made especially for lees-than-truckload applications of single-axle tractors. Used in the drive axle position, the BDR-HT3 incorporates a tread compound and tread pattern that resists tears. The bowtie-shaped tread block distributes torque forces evenly for reduced block stress, while the wider, buttressed shape design strengthens the block, helping it stand up to heavy torque and braking, the company says. Tie bars link tread blocks to neighboring blocks, designed to reduce effects of tearing and cracking, while an interlocking tread design and slightly angled block edges combat heel and toe wear. The BDR-HT3 has an open shoulder and a 28/32-inch tread design.
