fuel efficiency factors

Conclusions

After nearly three decades of testing, Bridgestone engineers have concluded there are so many factors affecting large truck fuel economy that it is almost impossible to accurately predict the effect of changing them without thorough real-world testing.

And, as the Technology and Maintenance Council and others have pointed out, some fuel economy methods – that have nothing to do with tires – can accomplish much more than changing tires can.

We've summarized TMC's statements in the chart shown below. You'll notice the improvement you can expect varies considerably, and you will no doubt find some methods are easier for you to implement than others.

The chart below, derived from TMC data, shows the top ten controllable fuel economy factors.
