Every day – as you drive to and from work, drop the kids at daycare or soccer practice, buy groceries – air is constantly escaping through the walls of your tires. Oxygen molecules, which are smaller than nitrogen molecules, seep through three to four times faster. A tire filled with “plain old air” will lose 1.5 psi in less than a month; with nitrogen, this can take six months or longer.
With nitrogen in your tires, they will maintain proper pressure longer. Properly inflated tires not only reduce the chance of a blowout, they also ensure that the recommended “contact patch” is on the road. That improves your vehicle’s handling so you can react more quickly and decisively in potentially dangerous road conditions and situations.
