Too often, drivers want to know how often they should add more air to their tyres. There are some factors that determine that and this post has listed them out. Check it now!

The air pressure in a tyre can overly change without you noticing it. This always depends on the temperature outside. During the rainy season, the cold temperature affects the tyre pressure in such a way that the pounds per square inch (PSI) drastically falls up to 5 pounds. Most car tires require a PSI that ranges from 30 to 40. So, when your tyre loses 5 pounds per square, it will cause a sharp change. Here, a major issue is imminent if you do nothing about it. And this is when you may begin to ask the question: how often should I inflate my tyres so that they can function properly?

This post on Naijauto will be answering the question, as we go on.

1. How often should I inflate my tyres?

In the past, a tyre gauge is always carried along to help check the air pressure inside the tyres. But these days, technological advancement in the automobile industry now enables one to monitor their car's tyre pressure. Your car can let you know when there’s a need for a refill.

Talking about when the tyres need an air refill, there are some factors that get to decide that.

2. Factors that decide how often car tyres should be inflated

These factors are the tyre pressure, driving pattern of the driver, and the load or weight on the tyres. Car manufacturers always have the recommended tyre pressure written down on the owner's manual or a sticker placed on the driver's door.

2.1. Tyre pounds per square and tyre pressure

The average pounds per square (PSI) for cars, small trucks are between 27 and 32. For a pickup and full-size SUV, the PSI is 5 to 8 higher. This is to take in the size and extra weight.

And now to the tyre pressure as a factor. When we talk about the tyre pressure, you should know that it te

Auto experts believe that when you add some pounds of air to the tyres, it will improve your gas mileage as the tyre's rolling resistance is decreased.

2.2. Extra load

If you're going to be carrying an extra load with your car, it’s advisable to add some air to the back tyres only to balance the extra weight added to the tyres. While you're at it, don't go adding beyond the tyre manufacturer's recommended level, that is, the air pressure that the tyre's is meant to hold. This is because going beyond the recommended level can cause damage to the tyre.

Always conduct a regular check on your car's tyre pressure as tyres leak air faster. A car can lose up to 1 pound a month based on regular driving and if it goes beyond this, the rim may be leaking. So, it becomes necessary that you carry out a thorough inspection whenever you intend going for a long trip. And the best time to do the check is when the weather is cold or in the morning. Hot temperatures tend to increase the air pressure than what it actually is.
