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)

By Jim Park

Why should we worry about defining underinflation? Because of the Federal Motor Carrier Safety Administration's CSA (Compliance, Safety, Accountability) enforcement program.

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.

Tires are Key Component of CSA Inspections

By Truckinginfo Staff

As one of the two biggest non-labor expenses that trucking fleets have, tires require careful maintenance. The Federal Motor Carrier Safety Administration’s Compliance, Safety, Accountability program further underscores the importance of good tire maintenance practices.

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

The economic recession had profound effects on trucking, but one of the most surprising is a greater need for tires on trucks that need to be used in more than one application. That's the opposite of another trend, which is more single-application-specific tires.

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.
