How Tires Affect Fuel Economy Testing

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.
