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.

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

Underrated steer tires can be hazardous. Steer axle loads approaching 13,000 pounds are not uncommon today.

By Jim Park

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. Are you running a steer tire rated for that weight?

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.

Retreads Shop Can Produce 75% More Retreads Daily

By Bob Ulrich

More than 85% of the estimated 680 domestic retread plants have been in business more than 20 years. It is safe to call retreading a mature market, based on the results of the 2013 Modern Tire Dealer Retreaders Survey.

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.

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.

What Exactly Constitutes an Underinflated Truck Tire?

"Underinflated" isn't always this obvious. Enforcement officials are looking for a usable definition. (Photo by Evan Lockridge)

Wheel-End Problems: Beyond the Obvious

Customers complaining that bad tires are suffering irregular wear? The problem may lie somewhere in the wheel-end. Photo by Jim Park.

By Jim Park

Wheel-ends function as a system: the spindle, hub, and rim (or wheel), as well as the bearings and the fasteners, all work in concert to keep the wheels in place and the tires running straight and true. 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.

Making the Case for Fuel-Efficient Tires

The more rubber you have on the road, the sooner the improvements become obvious.

By Jim Park

You get 30% less tread on some fuel-efficient tires, they cost 15% less up front and they run fewer miles to take-off, but does the money saved on fuel because of the lower rolling resistance make up for the shorter overall life? Many fleets are struggling with that question today. The answer is often anything but clear.

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.

What You Need to Know About Wide-base Singles & Offset Axles

Wide-base single tires are popular for weight and fuel saving, but not everybody likes them. Spec'ing to revert back to dual tires at resale needs special consideration.

By Jim Park

Everything you need to know about switching from dual wheels to wide-base singles you can learn at a playground. Picture a teeter-totter with a big kid on one end and a little kid on the other. The big kid is on the ground, while the little guy's legs are dangling in the air. The load is unevenly distributed. If you moved the fulcrum closer to the big kid, the beam would eventually balance.

Tire Makers Look for Alternatives to Natural Rubber

Guayule is a rubber-producing plant that could offer a domestic, and thus more stable, supply.

By Jim Park

Although we're in no danger of running short of our primary source of natural rubber, prices have risen dramatically over the past 10 years, contributing to rising prices for tires. Several tire makers are researching other sources of rubber.

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.

Tires for multiple applications

By Evan Lockridge

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.
