Car tyre valve caps play an important role in looking after your car tyres. These tyre caps plays an important role in tyre pressure and, if you don’t look after them, they can cause you to lose some of the quality and safety parameters from your products.

Here, we answer some of the most common questions about tyre air caps, to help you better understand their vital role.

How Do Tyre Valve Caps Influence Driving Safety?

Your tyre valve cap can have a greater influence on your safety than you might otherwise expect! When your car tyre valve caps are missing, dirt gathers around the valve stem, often being pushed into the tyre when it is being inflated.

It often results in the valve not closing correctly and this can cause the tyre to lose pressure. Consequently, the insufficient pressure values will have a direct impact on your safety.

Is There A Way To Prevent Dirt From Getting Into An Uncapped Tyre Valve?


If the car valve caps are not in place, the open valve will inevitably attract dirt.


Tyre valve caps are often underestimated by car and SUV owners.

What can you do if it turns out you were driving without tyre valve caps and you are worried that a compressor will push the dirt into the tyre valve?

The easiest method is to let some of the air out of the tyre before you use the compressor. Push the tyre valve with a hard tool until you hear the distinctive hissing noise. You may need to repeat this process a few times to clear a sufficient amount of air.

This method is not fool-proof, but it can be helpful. It highly depends on how much dirt got stuck around the tyre valve while it was uncapped.

When do I need the tyre valve caps most?

Tyre valve caps are arguably more important in countries that don’t have the cleanest streets and roads. They are needed to minimise the risks of passing through puddles, mud, sand and other hazards where dirt can easily enter the tyre valve.

Are the tyre valve caps worth buying?

In short: yes. Definitely. Considering how cheap car valve caps are, everyone should be buying them. Compared to the overall cost of car maintenance, these caps are an insignificant expense that may save you from future problems and further expenses.
