Results of the National Academy of Sciences' National Tire Efficiency Study will be released on April 4. The study is being sponsored by the National Highway Traffic Safety Administration.

The study was implemented to "consider the relationship that low rolling resistance replacement tires designed for use on passenger cars and light trucks have on fuel consumption and tire wear life," according to National Academy of Sciences officials.

Other goals include:

1. addressing "the potential for securing technically feasible and cost-effective replacement tires that do not adversely affect safety, including the impacts on performance and durability, or adversely impact tread life and scrap tire disposal."

2. considering "the American 'drive cycle' in its analysis."

3. addressing the cost to consumers, "including the additional cost of replacement tires and any potential fuel savings."

The study started December 2004.
