4. Treadwear â The Treadwear rating (on the sidewall and the new tire sticker) is a number; the larger the number the longer the tire will last. The Treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course.

Secondary biofuels result from processing of biomass and include liquid biofuels such as ethanol and biodiesel that can be used in vehicles and industrial processes. Bioenergy is mainly used in homes (80%), to a lesser extent in industry (18%), while liquid biofuels for transport still play a limited role (2%).he most widely used liquid biofuels for transport are ethanol and biodiesel. Ethanol is a type of alcohol that can be produced using any feedstock containing significant amounts of sugar, such as sugar cane or sugar beet, or starch, such as maize and wheat.
