Top 3 Ways to Preserve Tire Life (And Value)

Even the best tires money can buy will profit from a little help. Basic maintenance can prolong tire life, sometimes dramatically.

By Jim Park

Still waiting for the million-mile tire? Don’t hold your breath, but we’ll probably see such a tire in our lifetime. For now, you’ll have to settle for half a million miles.

Making the Case for Low-Rolling-Resistance Tires

Premium all-position tires offer reduced rolling resistance through ribbed tread patterns and shallow grooves.

By Jim Park

How do you explain to the boss that the tires you want to buy are going to cost more up front but run fewer miles? You can explain they will save money on fuel, but then she's going to want numbers.

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.

What's this Cold Weather Doing to Your Tire Pressure? (updated)

By Jim Park

Here's one more reason to fear the dreaded Arctic Vortex: It plays havoc with tire pressure. If you're based in North Dakota and your trucks never travel too far south or west, there's hardly anything to worry about. San Diego-based fleets running up into the Midwest and the Dakotas or vice versa could have a problem.

Mismatching Dual Tires: A Sure-Fire Way to Kill Two Tires at Once

Mismatched tire sizes means the shorter tire is chasing the taller tire down the road, and scrubbing away value with every mile.

By Jim Park

As tire costs continue to rise, it will become harder to ignore even seemly insignificant problems, like mounting two tires of different diameter in the same dual assembly. Lack of attention can strip thousands of miles from even scabby old trailer tires, and increase the risk of a mission-crippling blowout.

Who Balances Trailer Wheels?

(Photo by Jim Park)

By Jim Park

Nobody balances trailer wheels, but oddly, they are the wheels on a truck most likely in need of balancing. With a few ounces of balancing material, those tires might easily run tens of thousands more miles before final removal.

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.”

Are We Sacrificing Traction for Fuel Economy?

In most cases the traction losses are practically non-existent between traditional and fuel efficient tires.

By Jim Park

As more fleets embrace their fuel savings potential, a large portion of the driver population remains uneasy about low-rolling-resistance, fuel-efficient tires -- especially in winter. Has the quest for fuel efficiency pushed traction and safety into the back seat?

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.

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.

Studies Indicate TPMS and ATIS Are Money Makers

Soft, underinflated tires increase rolling resistance and shorten tire life. TPMS and ATIS systems solve both problems at once.

By Jim Park

There are lots or reasons not to embrace fuel-saving technology (some better than others), but validation exists for tire-pressure mitigation systems. And the payback is significant.

The Magic Number

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

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.

4 Ways to Get More Miles from your Tires

By Jim Park

Irregular tire wear is usually a symptom of some other malfunction such as poor alignment, improper inflation or even poor driving habits. The peril with mechanically induced irregular wear is that it begins the day you install the tire, though it won't produce any visible signs until weeks or perhaps months later. By then, its progress is almost irreversible.

Why Should You Retread Your Tires?

You can choose from a wide range of OE and aftermarket tread patters and compounds to optimize tire life or fuel efficiency. EPA now recognizes retreads as fuel efficient tires, so fleets can reuse the same casing for different applications at different wheel positions.

By Jim Park

Retreading tires provides the absolute lowest cost per mile of any tire management strategy. When coupled with other enhanced preventive maintenance measures, a retreaded tire can easily go half a million miles or more, all things being equal.

Preventing Flat Tires

Once the tread comes off, a blowout won't be far behind. You're down, with a $1,000 repair bill to show for it.

By Jim Park

A driver picks up a trailer from a drop yard. Before departing, the driver does a walk-around inspection, kicks the tires, checks the lights and then sticks it into the wind. He or she has no idea how much air pressure is in those tires, except to be fairly sure none of them is flat — visibly flat, that is. Any one or several of those tires could be underinflated, or even technically flat.

Why You Should Consider Wheel Balancing

Tire wear associated with balance problems often appears as cupped channels along the tread face of the tire. (Photo: TMC)

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.
