According to Sergio and Daniel, improper tire air pressure can affect your mileage up to 3%. Improper air pressure can increase our use of gasoline which then leads to higher use of fossil fuels that contribute to green house gasses. This in turn affects our watershed. Sergio and Daniel hosted several tire clinics at their school to educate their peers about the issue. They also checked their peers’ tire pressure and aired them up to the appropriate tire pressure for those that needed it. These students also collected data on their peers tire pressure and collaborated with Les Schwab tire whom assisted them with the tire clinics. Each student to have their tires checked received free snacks and a tire pressure gauge. Of all the cars they tested, 50% of those cars needed air. Their calculations show that 13 cars saved 3.8 gal of gasoline each week once their tires were filled to the appropriate amount which computes to over 2 tons of CO2 not entering the Poudre watershed.
