Fleet managers once reluctant to use retreads now have embraced retreads in their standard operating procedures. According to a recent NRMCA survey, more than 96% of fleet managers use retread tires for the drive position. Surprisingly, 19% of the survey's respondents indicated they also position retreads on the steering-positioned wheels.

Ready-mix fleets often have a casing deficit. Delivery-site pitfalls, including nails and rebar ends, often ruin a casing before the encircling tread is worn to its pull-depth. To use recaps, producers often must purchase cores a tire distributor has purchased from other trucking applications where cores have less stressful service.

Perhaps Randy Burgess, fleet manager at Shamblin Stone, Inc., Dunbar, W. Va., has started an incentive-bonus system that rewards drivers whose drive-tire life exceeds a specific fleet-wide mileage. This past year Shamblin Stone added a driver bonus for good steer-axle tire wear. "We are now discussing expanding it to include drive-axle tires," says Burgess.
