Like many other industries and products, it is not surprising that some things are possibly misunderstood when it comes to recreational vehicles. These misconceptions often lead to the developing of believable myths. Though we can not possibly address all of these we can look at a few of the more common beliefs.
Myth
Filling your RV tires with nitrogen instead of compressed atmospheric air will alleviate the need for topping up the pressure from time to time.
This is not true. While nitrogen may reduce the frequency of topping up the tire pressures, it does not alleviate this need entirely. Nitrogen molecules are larger than that of oxygen and therefore pass through the tire casing at a lesser rate. However, there are other benefits that the nitrogen fills provide, such as less volume variation with tire temperature changes. Atmospheric air contains 78% nitrogen and 21% oxygen.
