Goodyear Tires
All tires are Goodyear, and all except the wide-base mixer steer tires are 11R22.5 sizes. Dump trailers and bulk-cement trailers ride about 85,000 miles on Goodyear-recapped casings.

Tire failures had become a problem at Lattimore Materials. The Dallas-area concrete and aggregate supplier's 400-truck fleet was suffering as many as 12 road calls a month, not including punctures inflicted on construction sites.

In 1999, Goodyear suggested a simple solution: maintain inflation pressure. Drivers were required to gauge tire pressures each morning. Every valve stem now has a flow-through valve cap. Each truck has a calibrated pressure gauge.

"Before, about half of our tires were underinflated," says DeLynn James, manager of fleet maintenance. "Today, about 96 percent of our tire pressures are accurate."

Mixer drivers are also required to inspect tires before accepting each load.

"If a driver loads up with a low tire and he has a flat on the road, he loses his production bonus for the day," says James. "We've cut our road calls in half."
