Nitrogen in Car Tyres: Is it Worth the Switch?

Have you ever noticed an additional meter at your local petrol station specifically dispensing nitrogen for car tyres? If you're thinking about switching from traditional air to nitrogen in your tyres, it's good to know that nitrogen can enhance tyre health to a certain extent. This article aims to provide you with a comprehensive understanding of this topic.

The Benefits of Nitrogen in Tyres

The key benefit of nitrogen-filled tyres is that it helps maintain tyre pressure and cooling. Although conventional air consists of 78% nitrogen, inflating your tyres exclusively with nitrogen can help keep the pressure steady for a longer duration.

This is because nitrogen molecules are larger and slower moving than compressed air, meaning they can't escape the tyre as quickly, thus maintaining an optimal pressure for a more extended period.

Tupkeshwar Uppal, a global executive for a well-known tyre company, suggests that nitrogen can help keep tyres in good condition. However, he points out that the cost might be a deterrent for customers since, unlike air, nitrogen isn't free.

How to Properly Use Nitrogen in Car Tyres

Before filling your car tyres with nitrogen for the first time, it's essential to remember that they need to be fully deflated and then inflated with nitrogen. The cost per tyre is around Rs 25, and it is recommended to top up once or twice a month.

While some pumps may offer free nitrogen if you fill up your tank, it's also possible to mix air and nitrogen if needed. For instance, if you're in a location with no nitrogen kiosks around and your tyre pressure is low, you can top up the nitrogen with air.

Pros and Cons of Using Nitrogen in Tyres

There are several advantages to using nitrogen in your tyres. Because nitrogen is naturally cooler, your tyres won't heat up as much, especially on long drives. The reduced leakage compared to air means your tyres won't wear out as quickly, and your car's handling will improve. Additionally, nitrogen contributes to relatively consistent tyre pressure, even with temperature fluctuations, helping in fuel economy.

However, the use of nitrogen in tyres comes with its own set of disadvantages. The cost of nitrogen can be a significant factor, as most places charge per tyre. The initial process of completely deflating the tyres to fill with nitrogen can consume a considerable amount of time. Moreover, nitrogen is not readily available everywhere, which might force you to mix it with air if the pressure drops.

In conclusion, using nitrogen in your car tyres can indeed provide some benefits, such as improved tyre health, better car handling, and enhanced fuel economy. However, it's essential to weigh these advantages against the potential drawbacks like the additional cost, time consumption, and limited availability of nitrogen. Ultimately, your decision should be based on personal preference, driving habits and local availability of nitrogen.
