As a regular driver, I've always wondered how tire tread wear could affect my gas mileage. After doing some research, I found out that worn-out tires actually reduce fuel efficiency. This happens because the increased rolling resistance caused by lower tread depth makes the engine work harder to maintain the same speed. In turn, this causes the vehicle to consume more fuel. So, keeping your tires in good condition not only ensures a safer drive but also helps save money on gas!
