How Tires Affect Fuel Economy Testing

Apples to oranges. Accurate fuel economy test results can only be obtained using idendical trucks, including the tires.

By Jim Park

When setting out to evaluate a fuel-saving product, you don't want your numbers skewed by differences in rolling resistance from the tires. With some fuel-saving devices promising only marginal gains, the tires' contribution to the fuel consumption can adversely affect the apparent performance of the product. Here's what to watch for when setting up an evaluation or testing program.

The Benefits of Low-Rolling-Resistance Tires Explained

By Jim Park

There's little doubt left that tires formulated for lower rolling resistance work as advertised, but it's still tough to give up at few thousandths of an inch of tread. After all, tire miles are important, too. How much of a difference does the reduction in rolling resistance make?

Inflate your Tires, Not Your Fuel Bill

The harm from overinflating tires, especially those that run a high percentage of unloaded miles, could outweigh the perceived gains in fuel efficiency.

By Jim Park

For as hard as fleets work for a 1% gain in fuel efficiency, it's hard to imagine giving up something like 2-4% in fuel efficiency to something as simple as maintaining correct inflation pressure, especially today when almost every inflation or monitoring system on the market offers payback in less than a year.

The Lowdown on the New Low-Viscosity Oils

Kinematic viscosity is what you might envision when thinking of viscosity – gravitational flow. But the new oils will meet viscosity standards measured at high temperatures/high shear conditions.

By Deborah Lockridge

Exactly what is this "high-temp, high-shear" viscosity engine oil standard in the works for the next round of EPA emissions standards, and what are engine makers doing to make sure engines will still be well protected?
