Sa pag kakaunawa ko di pwede kasi sayang lang ang nitro sa tire pag may halo na compressed air. correct me if i'm wrong.
Quoted:
One of the most important parts of your car is each of the four tires. They constitute the interface of your car with the road. Given their importance, doesn't it make sense to give some thought to what you put in the tires to inflate them? The issue boils down to nitrogen versus compressed air.
Tire pressure and performance is one of the most abused elements of car by drivers. The vast majority of people never even test the pressure of the tires unless the tire is visibly going flat. As a result, various studies have found that upwards of 90 percent of cars are driving on underinflated tires. This impacts the handling of your car and the tire wear. The next time you complain about the cost of replacing your tires, remind yourself that checking the pressure once a month would very likely have made them last much longer!
In the world of auto racing, every little advantage can make the difference between winning and finishing in the back of the pack. Given this fact, it probably is no surprise that teams in the various championships have given tires a lot of thought. Not only have the tires become very high tech, but they are not even filled with air anymore. Nope, teams go with nitrogen. The question for you and me is whether we should do the same in our street cars?
Why nitrogen? The answer is found in something known as "inertness". Simply put, nitrogen is an inert gas at less than extreme temperatures. The compressed air you find at the gas station is not. Oxygen is a key component in its makeup. This means the potential for oxidation is present. Over time, oxygen will degrade the inside of the rim and it will attack the steel belts in the tires.
Another difference between the two has to do with pressure maintenance. There are technical differences between how the two gases are combined on a molecular level. For the purposes of this article, all you need to know is nitrogen is bound in such a way that it tends to maintain the average pressure in the tire about three times as long as compressed air. It also tends to maintain that pressure regardless of the temperature of the tires, while compressed air will heat up and cool down.
So, should you go with nitrogen over compressed air for your tires? Nitrogen is definitely better than compressed air, but the value of this improvement is negligible on a commuter car. If you have expensive rims and/or tires, then it is probably worth it to protect them from oxidation. If you are just putting around in your Honda Civic, it probably isn't. Just make sure you check the tire pressure each month to avoid unnecessary wear and tear.
