It's in racing tires, the space shuttle's tires and now it's here for your tires!

Nitrogen is used to inflate racecar tires, aircraft tires, military vehicle tires and even the space shuttle's tires. Why? Because professionals in racing and aerospace and the military recognize the safety and performance enhancements nitrogen has to offer. Simply put, Nitrogen makes tires last longer, perform better and more safely, and function with more reliability than tires filled with air.

Simple and Safe!

Nitrogen is a safe, more stable alternative to filling your tires with air because it leaks out naturally much more slowly and does not react to changes in outside temperature. That means your tires will remain properly inflated much longer, reducing wear and improving fuel mileage! It is a completely safe, dry and inert gas that is already in the air you breathe.

All tires leak air out slowly through a tire's rubber walls. That's why you need to check pressures regularly, and why you often find your tires are surprisingly under-inflated. Improperly inflated tires wear out much more quickly, decrease your fuel mileage and can sometimes result in complete tire failure. Since Nitrogen molecules are larger than air molecules, they leak out 3 times more slowly than air. So with nitrogen in your tires, they will remain correctly inflated for a much longer period of time and be able to handle the load capacities they were designed for. This results in extended tire life, improved gas mileage and improved handling and safety.

Nitrogen helps take some of the worry out of correctly maintaining your tire pressures by keeping them correctly inflated up to 3 times longer than air. That means you won't have to check them as often. Of course, Belle Tire recommends still checking tire pressure on a regular basis.
