Nitrogen. while pricier than regular air. requires an extra fee to fill your tires. This can make it difficult to locate since it is not readily available at all gas stations. Despite its higher cost. there is no significant improvement in fuel economy when using nitrogen in tires. While some believe that nitrogen filling promotes longer tire life. the difference is usually minimal. Additionally. even with nitrogen-filled tires. it is still necessary to regularly check the pressure as they naturally lose it over time. In situations where replenishing with nitrogen is not feasible. regular air must be used to dilute the concentration in the tires. It should be noted that some may mistakenly assume that nitrogen-filled tires do not require routine maintenance and have a false sense of security; however. this is not the case.

Run-flat tires can usually travel up to 500 miles at 50 mph after a puncture or complete loss of air pressure. but it depends on the tire make and model.

They are known for their high reliability scores. advanced safety features. and comprehensive warranties. Different models may offer different benefits. so it's important to research and test to find the model that best suits your needs.
