Adopting Tire Inflation Systems

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

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.

Keeping Your Wheels On

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.

Retreading Wide-base Tires

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.

Steer Axle Weights Have Increased: Are Your Steer Tires up to the Challenge?

It’s not uncommon to find highway trucks with front axles and suspensions rated for 13,200 pounds. While 12,000-pound axles were the industry norm for many years, the move to 13,200-pound axles came with the addition of all that emissions reduction gear.

The Magic Number

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.

If one part of the system is out of whack, the results will be seen and felt elsewhere in the system - usually at the tires themselves.
