Automobile transport drivers conducting car shipping services for an American car transporter that have been dreaming of a low-rolling-resistance, fuel-efficient retreaded tire that has been certified by the United States Environmental Protection Agency's SmartWay program might be able to stop dreaming in a few months time. Car movers need only look at the United States Environmental Protection Agency's list of low-rolling-resistance, fuel-efficient tires will tell you that there are no retreads on the list at the present moment. This could change by sometime in 2011, now that the interest in getting retreaded tires onto the SmartWay list, has apparently increased sufficiently to get the ball rolling, according to the latest sources.
Why aren't retreaded tires on the United States Environmental Protection Agency's SmartWay list already? Sources around the car hauling industry indicate that the Environmental Protection Agency could be having a little trouble finding away to quantify the relative fuel efficiency of a retreaded tire, which is a two-part system. That casing and treads are designed to work together, but the variables involved in testing makes it difficult to objectively quantify the measurements obtained during the tests. The Environmental Protection Agency therefore had the tire manufacturers of America work together on developing a system to help the Environmental Protection Agency sort through the multitude of treads and casings on the market that could conceivably one day become a single retreaded tire.
These could be just the beginning of the challenges in front of the desire to get retreaded tires onto the Environmental Protection Agency's SmartWay program though as there could also be problems classifying retreaded tires within the current contest of the SmartWay program. Do you measure the casing or the tread and how do you measure the rolling resistance contribution of the tread and the casings? Every retreaded tire is going to be a unique product because of the history of the casing of the tire in question and this is going to make it extremely difficult to measure the rolling resistance values for each casing.
