Is It True That Underinflated Car Tires Waste Energy?

Is It True That Underinflated Car Tires Waste Energy?When car tires are not inflated to the PSI (pounds per square inch) rating recommended by manufacturers, they are not as ‘round’ as they should be and therefore need more energy to move and maintain speed. So yes, underinflated car tires do increase fuel costs and contribute to pollution.

The majority of cars on American roads are driving on car tires inflated to only 80% of their capacity. What’s more, gas mileage can be improved by 3.3% when car tires are inflated to their correct pressure. In contrast, leaving them underinflated can reduce gas mileage by 0.4% for every PSI drop in all 4 car tires.

That might not sound like a lot, but it means that someone who drives 12,000 miles a year on underinflated car tires will use 144 additional gallons of gas. And each time a gallon of gas burns, 20 lbs. of carbon dioxide enters the atmosphere when the carbons are released and mix with oxygen in the air. Therefore, any vehicle that runs on soft tires is adding as much as 2,880 lbs. (1.5 tons) of extra greenhouse gases to the environment every year.

Apart from saving money and fuel and reducing emissions, correctly inflated car tires are less likely to fail at high speeds, so they are safer. Longer stopping distances are required for underinflated tires, and they will skid for longer on wet surfaces. Experts blame underinflated tires as the probable cause of many SUV rollovers. Correctly inflated car tires will last longer and also wear more evenly.
