Nitrogen tyre inflation


Why Nitrogen?

Filling your tyres with nitrogen instead of compressed air means that your tyre pressure will remain at the recommended threshold for longer. The rate at which nitrogen passes through tyre walls is slower than regular air.

Our cutting-edge equipment removes the existing air in your tyres and refills them with purified nitrogen. Nitrogen inflation keeps your tyres at the correct pressure for longer.


This also reduces fuel costs, increases tyre life, improves handling, and lowers Co2 emissions.

The science behind nitrogen tyre inflation

Here at Andrew Dodds Autocare in Ayr, we choose nitrogen over compressed air. Although tyres operate well with normal air inflation, nitrogen can improve your tyre life and performance. Below are three main benefits of nitrogen inflation.

Slows Pressure Loss

When you opt for nitrogen-filled tyres, the pressure loss slows by about 40 per cent. Nitrogen leaks less than normal air, ensuring your tyres maintain better pressure for longer. This results in superior tyre performance, safety, and fuel mileage.

Minimise Vapour

Tyres don’t do well with internal water vapour, and thankfully, nitrogen gas is usually very dry. Vapor can cause fluctuating air pressure with temperature changes, making it more challenging to maintain the appropriate tyre pressure.

Less tyre degradation

Nitrogen inflation reduces the rate of the thermo-oxidative process, which can cause the degradation of rubber over time. Ordinary air is composed of 78 per cent nitrogen, but the remaining percentage of oxygen is what reacts with the rubber as it diffuses through it.


What is nitrogen tyre inflation?

Nitrogen tyre inflation is when you fill your tyres with pure nitrogen as opposed to normal compressed air.


Pure nitrogen is a non-flammable gas that doesn’t absorb moisture, making it a better choice for your tyres. In fact, it’s what aviation, construction, mining, and professional racing vehicles use.

Nitrogen tyre inflation frequently asked questions

  • Is nitrogen tyre inflation worth it?

    The most significant benefit of nitrogen over normal air is that your tyres wear down much slower. Plus, nitrogen has a lower risk of explosion. However, nitrogen is more expensive than normal air, so it depends on your budget. It can save you money in the long run, making it a worthwhile investment.


  • Can I mix nitrogen and air in my tyres?

    Yes, you can. Mixing nitrogen and air in your tyres won’t cause any harm. Keep in mind, if you bring your car to Andrew Dodds Autocare for nitrogen tyre inflation, we will remove all compressed air first, ensuring that you have 100 per cent pure nitrogen in your tyres.


  • Where can I inflate my tyres with nitrogen?

    At Andrew Dodds Autocare in Ayr, we can inflate your tyres with nitrogen. We will deflate the tyres first to remove normal air before refilling them with nitrogen. Call us when you need your tyres topped up, and we can pump in more nitrogen.


  • What are the disadvantages of nitrogen tyre inflation?

    The main drawback is cost, as it’s slightly more expensive than regular air. It also can be tricky to find dealers that use nitrogen to pump up your tyres. Many garage air pumps still use compressed air. But you can always call us to top up your tyres with pure nitrogen.
