Regardless of the type of tires you use, maintaining<br />
correct inflation pressure for the load will optimize<br />
tire performance, tire life, <strong>and</strong> fuel economy.<br />

In general, trailer tires make the largest contribution.<br />
If you are evaluating tires, you should probably try<br />
fuel-efficient trailer tires first. If that doesn’t work,<br />
changing drive <strong>and</strong> steer tires probably won’t either.<br />

What effect can fuel-efficient tires have?<br />
Generally you will only see about half of the scientific<br />
test results in the real world. Much of this is because<br />
of interference by other factors outside the controlled<br />
variables of testing.<br />
So, any fuel economy method that does not<br />
produce at least a 2-percent improvement in<br />
controlled testing will probably not produce a<br />
measurable real-world effect.<br />
Taking action<br />
BBTS recommends you conduct your own tests to<br />
determine whether your investment will achieve a<br />
satisfactory return.<br />
Comparing fuel receipts with odometer readings is<br />
something you can do yourself, on an ongoing basis,<br />
to see if your fuel economy program is working.<br />
Here are some steps to take:<br />

other methods: Driver behavior has a<br />
big effect on fuel economy. Driver training or<br />
incentives may be a better investment than new<br />
equipment.<br />
your priorities: Make sure everyone is<br />
on board. If one department is trying to save fuel<br />
<strong>and</strong> another is trying to cut tire costs, they may<br />
be working against each other.<br />
