Overinflating tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes, etc. Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. ! Do not operate the electric air pump longer than 8 minutes without interruption. Otherwise it may overheat. You may operate the electric air pump again after it has cooled off. Detach the electric air pump. 446
