Nitrogen Instead of Regular Air in My BMW Tires
There’s a lot of hype out there about using nitrogen instead of regular air in your BMW tires. People claim that it gives you a better ride, improves fuel economy and extends tire life. However, many of these claims are exaggerated or simply don’t apply to street-driven vehicles.
Nitrogen is a colorless, odorless gas that’s considered to be inert. It’s also a safe, non-flammable, non-toxic substance. It’s been used in airplane and race car tires for years because of its unique properties. For example, it can’t ignite when exposed to flame or high temperatures, which means that tires filled with nitrogen are safer and more reliable than those filled with air.
The main reason to use nitrogen in your BMW tires is that it doesn’t seep out of the Buy BMW tire wheels at the same rate as oxygen, which allows your tires to stay properly inflated longer. In fact, most newer cars come from the factory with their tires pre-filled with nitrogen. This is because manufacturers recognize that a well-inflated tire provides more safety, better fuel economy and an overall superior driving experience.
Can I Use Nitrogen Instead of Regular Air in My BMW Tires?
Air is made up of 78 percent nitrogen and just under 21 percent oxygen, with the rest being water vapor, carbon dioxide and small amounts of noble gases like neon and argon. When you fill your tires with compressed air, the amount of nitrogen increases to about 93 to 95 percent.
A single nitrogen atom is larger than an oxygen atom, which means that it occupies more space. Therefore, it takes up more room in your tires than oxygen, so it’s harder for the oxygen molecules to escape your tires as they leak. This allows nitrogen to replace the oxygen in your tires, preventing them from getting low and losing pressure. This is why the tires on newer cars tend to stay inflated for longer periods of time.
In addition, nitrogen doesn’t carry moisture, which can cause a variety of problems for your vehicle. Moisture can lead to improperly inflated tires, which can cause poor handling and reduce fuel efficiency. It can also contribute to the degradation of rubber, which decreases tire longevity. Nitrogen keeps moisture out of your tires, which can help to protect the valve stem and wheel rims.
In general, the minimum recommended tread depth for winter tires is 6/32 of an inch. However, many experts suggest considering replacing winter tires when the tread depth reaches 4/32 of an inch for optimal safety and performance. This recommendation is based on the fact that as the tread wears down, the tire’s ability to channel away slush, snow, and water diminishes, leading to reduced traction on slippery surfaces.
While nitrogen may help to keep your tires more fully inflated, it’s important to remember that it’s still not a substitute for routine inflation pressure maintenance. Most experts recommend that you check your tire pressures regularly, no matter what kind of gas you put in your tires. You should always check your tire pressures with a quality tire pressure gauge and make sure that they’re at the recommended pressure for your vehicle.
