Hi! Dylan here. When I'm on Martha's Vineyard and we are driving onto the beach we always have to release the tire pressure in order for the tires to be able to drive in the deep sand. The reality is, less tire pressure is bad for the environment. Keeping your tires inflated properly can increase your gas mileage by 3 percent. Every gallon of gasoline you save keeps 20 pounds of carbon dioxide out of the atmosphere. This is Dylan, signing off.
