The Goodyear Steer Tire Challenge guarantees the verifiable average removal miles of its G395 LHS on International 8000 and 9000i Series tractors will exceed the competition’s average removal miles, or Goodyear will retread the G395 LHS casing at no charge.

Last month, we asked why you shouldn’t indiscriminately switch your vehicles to a grease that’s different from what you’ve been using. At press time, we had not received a correct response, so we’ll let this one ride until the July issue. Keep those e-mails coming!

In the meantime, check out this month’s Puzzler. Send the first e-mail to [email protected] with the correct answer and collect a chrome CCJ pen and an Air Brake Book. The same offer goes if we use a Puzzler you suggest to us.

Bridgestone/Firestone North American Tire is on a roll with three new Bridgestone-brand truck tires – one for each axle position. The new tires were just rolled out at this year’s “Bizcon” meeting in Chicago. According to the company, the new R287 steer radial, M726 EL drive radial and R195F free-rolling trailer radial were engineered for longer original tread life and lower cost per mile.

The R287 steer radial offers a combination of irregular wear-fighting innovations, such as the Bridgestone Side Groove and Equalizer Rib, which combat edge and wavy wear in the shoulder and main ribs, while the 16/32-in. tread depth makes for less “squirm.” With advances that include a stiffer tread compound and a molded-in, footprint-shaped tread for even road contact, the R287 should prove popular with fleets who typically remove steers because of irregular wear, long before they are worn out. It’s available now in size 225/75R22, and other sizes will hit the streets during the last quarter of this year.

The M726 EL drive tire is an enhancement of Bridgestone’s well-established M726. With a 32/32-in. deep tread, this extra-life version incorporates irregular wear-fighting technology and a tougher tread compound. Availability is the same as that of the R287.

The 11/32-in. tread-depth R195F trailer tire uses sidewall protector ribs to fight curb and scrub damage, thus enhancing retreadability, while the Equalizer Rib and Defense Groove promote even wear and long original tread life. All sizes are available now, and the R195F will replace the 195 trailer tire this summer.

When remote-sensing alternators came along, they were recognized as a great improvement because they charged a vehicle’s batteries based on the actual need at the battery pack rather than on voltage at the alternator. But higher alternator output voltage is required to charge batteries as ambient temperatures drop and, until now, cozy, warm, engine-mounted alternators had no way of “knowing” the temperature of a heavy-duty vehicle’s outboard-mounted batteries.

Enter Smart Sense, a solid-state device that installs in the alternator and the remote-sensing lead, and adjusts alternator output based, not just on battery voltage, but battery temperature as well. The result is more efficient and complete battery charging under virtually all conditions, and fewer no-start conditions.

Smart Sense was developed by Purkey Fleet Electric and Vehicle Enhancement Systems, and is marketed through International Marketing Inc. (

FleetRunner – a new Gates Green Stripe engine belt – is designed with proprietary rubber compounds that greatly increase service life and resist belt failures due to the effects of prolonged engine heat.

A proprietary blend of EPDM (ethylene propylene diene monomer, if you must know) rubber allows the new belt to retain its flexibility on drives where extended high operating temperatures cause other belts to harden, crack and ultimately fail, says Gates. Fibers built into the belt improve stability and reduce belt turnover, while also lessening premature failures due to drive misalignment. The compounding also resists deterioration from ozone and water-based coolants.

To further increase service life, the new belt incorporates an underside notch pattern that provides flexibility and reduces bending stresses on drives with small diameter pulleys and short spans.

In field tests that included stop-and-go and highway running, Green Stripe belts lasted a minimum of twice as long as other belts on the most severe applications – 250,000 miles and more with only minimal signs of wear.
