| Don't underestimate the importance of proper tire inflation |
| Is it
possible to blow the importance of tire inflation out of proportion? Not
according to Dennis Munns, a specialist in four-wheel-drive loaders for
John Deere.
"Inflation means everything to loader performance," says Munns. "It has a dramatic effect on productivity, stability and ride." Not to mention the life of the tire itself. "Tires don’t heal," Munns explains. "Underinflate or overinflate and you’ll take life out of the tire." "As a general rule with four-wheel-loaders, you’ll want to run with rear tires and half the pressure of the front tires," he adds. "That surprises a lot of people. In fact, I’d venture to guess that 90 to 95 percent of front tires on wheel loaders out in the field right now are underinflated. "Lower tire pressure in rear tires tends to improve fore-aft stability and ride. Proper pressure in front tires improves side-to-side stability and tire life." So now we know proper inflation is important. Where do we start? Recommended psi is the starting point. You’ll find this information in the tire-maintenance manual that accompanies the tires upon purchase. Follow the instructions carefully for determining the correct tire pressure. Keep in mind, the weight of your machine and the typical weight of the load are critical factors in determining the correct pressure. Also consider that additional psi might be needed to provide the necessary stability. However, it’s important that you NEVER exceed the tire psi capacity. "All things staying the same, check tire pressure weekly at a minimum, but any changes in ground conditions or material being handled demands immediate attention," says Munns. "Cold inflation pressure is the baseline for tire pressure.""Also, when adjusting pressure, do so only in 2-psi increments (unless you know the exact pressure needed), otherwise it’ll really changes your handling characteristics." The good news is this: When you make proper tire inflation part of a complete tire management program, you’ll see substantial benefits to your bottom line.
