Keeping Your Wheels in the Game (updated)

Pictures are worth a thousand words, they say. What sort of a message do the wheels on this trailer convey about its owner?

By Jim Park

Back in 1984, the Occupational Safety and Health Administration issued a regulation requiring that truck wheels be stripped of rust and debris before mounting a tire. Easier said than done, the industry moaned at the time. Labor was less costly then, but wire brushes and elbow grease weren’t going to cut it.

Adopting Tire Inflation Systems

ATIS and TPMS do more than prevent good tires from coming apart. ROI also includes improved fuel economy, longer tread life and higher casing value.

By Jim Park

Why are adoption rates for proven fuel-saving technologies so low? It looks like a classic case of stepping over a dollar to pick up a dime. Maybe “a lack of credible information on payback” means, “we don’t know how much this device will save us so we’re not going to buy it.”

Why Balancing is Important

By Jim Park

If you look at balancing from a life-cycle point of view, the value of extending tread life speaks for itself. There’s also casing integrity to consider, retreadability, and to a growing degree, and disposal costs. Yet reliable estimates suggest only about 20% of heavy-duty truck tires are ever balanced.

Getting the Lead Out of Tire Weights

True rotation of a several-hundred-pound mass and high speeds requires balancing, not just of the tire, but the entire rotating mass, including the hub, brake drum, wheel and tire.

By Jim Park

Beware the lead tire weight cops. They are out there and working in six states, with several more states looking at banning lead weights. Here's a look at the alternatives to lead in weights -- and alternatives to weights themselves.

Keeping Your Wheels On

A calibrated torque wrench is required to set the recommended torque on wheel fasteners. Over-torqueing with an impact wrench can stretch and weaken the studs.

By Jim Park

There’s no mystery to why wheels come off trucks. The National Transportation Safety Board in 1992, and Ontario’s Ministry of Transportation in the late 1990s, both concluded after exhaustive studies that inadequate maintenance was the root cause of a series of fatal wheel separation incidents.

Why Do Wheels Come Off Trucks?

Drivers should be trained to inspect their wheels. Early detection can prevent a loose wheel from becoming a separation statistic.

By Jim Park

We don't hear many reports of wheel separations anymore, but that doesn't mean we have solved the problem. Reliable estimates suggest unplanned separations still occur at a rate of probably several per day. Exact numbers are hard to determine because many incidents go unreported.

Retreading Wide-base Tires

Most fleets could get a good trailer tire out of a third-generation retreaded tire.

By Jim Park

Wide-base tires aren’t cheap. Not that duals are cheaper, but in a single wide-base tire you have an investment approaching the cost of a pair of standard tires. Minimizing the life-cycle cost of those big wide tires almost demands that they be retreaded.

The Magic Number

Correct inflation pressure is dictated by weight, temperature and road speed – and the load and inflation tables.

By Jim Park

How do turtles mate? Why are women’s shirts buttoned on the left while men’s button on the right? How did they build the pyramids? How much air should I put in my tires? Unlike the pyramids, tire inflation needn’t be one of life’s little mysteries. Yet you may be inflating your tires TOO much.

Why You Should Consider Wheel Balancing

By Jim Park

People will tell you that wheel balancing isn't necessary these days. Going back 10 or 20 years, new tires often needed a small amount of weight to balance out the irregularities in the old production process. With today's more exacting manufacturing standards, irregularities are the exception. But that doesn't mean you can't benefit from wheel balancing.

Keep Tires Running Straight and True

By Jim Park, Equipment Editor

In tire and wheel mounting, the line between right and wrong is a thin one. A few thousandths of an inch on either side of correct can throw tires and wheels into a mean wobble or cause them to bounce up and down like pistons
