Nitrogen or air! Which is best for your Goodyear tyres?

If you’re confused on choosing between nitrogen and air for Goodyear tyres in Dubai, no need to panic! Many out there claim nitrogen being the greatest revolution over air. To some extent, it’s true especially if we look at scientific advantages, both nitrogen and air have their own benefits as well as a few drawbacks. Let’s have a look at some important factors to help you decide between the two.

Cost & convenience

It’s a fact that air for tyre inflation is universally available at a reasonable cost whereas some even fill the deflated tyres with air free of cost. This isn’t the case with nitrogen due to the complicated infrastructure which isn’t fully developed and unavailability of the compound everywhere. For each tyre, nitrogen can cost anywhere between $5 and $180 for a complete upgrade which is rather too expensive.

The complete upgrade from air to nitrogen is followed by a sequence of inflation and deflation steps several times to purge all the air. On the contrary, if you want Goodyear tyres in Dubai to last longer and perform at their optimum being highly effective, make sure nitrogen in 95 percent pure.

Just in case you encounter deflation with the nitrogen-filled tyres on the road where the compound isn’t readily available, you can always have them topped with air that wouldn’t hamper performance. However, do have the tyres refilled with nitrogen later after purging the air.

Overtime maintenance of the tyre pressure

Almost all tyres have microscopic pores through which gas or air seeps out over an extended period of time that gradually lowers the inflation pressure. As nitrogen molecules are larger than air, the seep rate is slower thereby keeping the tyres inflated for longer. A research concluded that nitrogen’s slight improvement mustn’t be considered a permanent substitute for regular inflation pressure checks. If you’re regularly checking pressure of those Goodyear tyres Dubai, spotting a pressure drop without incurring any extra cost of using nitrogen.

Fuel economy

The Environmental Protection Agency (EPA) has estimated approximately 0.3 percent drop in the gas mileage compared to every 1 psi drop in all the four tyres. Every drop in the tyre pressure increases its rolling resistance thereby decreasing gas mileage.

Yet another study indicated that using nitrogen for tyre inflation doesn’t change its rolling resistance which is the reason there isn’t any effect on the fuel economy.

Whatever the case, it’s always better checking the tyre pressure once in a month and keep the inflation to the recommended pressure thereby minimising the rolling resistance and maximising gas mileage.

Longevity & wheel corrosion

Air comprises approximately 78 percent nitrogen and 21 percent oxygen with remainder being trace gases. Oxygen can retain inside the tyres that gradually oxidises interior tyre wall casing that results in premature ageing of the tyres. In extreme cases, moisture can even rust the reinforcing belts and if protection paint of the wheel deteriorates, the rust would advance to the steel wheels as well.

Conclusion

The above details would surely help you choosing the best Goodyear tyres in Dubai, be it air or nitrogen-filled.
