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. For example a tire graded 150 would wear one and a half (1.5) times as well on the government course as a tire graded 100. Actual results will vary.

This energy release allows biogas to be used as a fuel; it can be used for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. Biogas can be compressed, the same way as natural gas is compressed to CNG, and used to power motor vehicles. In the UK, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel.
