Tyre Valve Caps

Tyre Myths: You Won’t Lose Air If You Use Valve Caps

What Job do Valve Caps Really Do?

Cars are designed with precision and thought. Every detail, even down to the small things, are placed there for a reason – that includes your valve caps. However, there is a lot of misinformation around what value caps are for. Do they stop the air coming out of your tyres, or are they for something else?

What Are Valve Caps?

Valve caps are placed on the stem of your vehicle tyres. They are small, made of plastic or metal, and may seem insignificant. However, they play an important role in tyre maintenance.

A valve cap is designed to protect the Schrader valve, which a valve stem core is threaded through. The stem core is what keeps the air or nitrogen in your tyres.

Why Do You Need Valve Caps on Your Tyres?

If a valve cap is not fitted to your tyres, the stem is left unprotected. Dirt and moisture can enter the valve stem, causing blockages or damaging the valve.

Not having a valve cap does make your tyres more susceptible to losing air. However, having your valve cap in place does not mean that your tyres won’t deflate.

What Should Your Tyre Pressure Be?

Tyre pressure is measured in PSI (pounds per square inch) and varies for each vehicle. Typically, on newer cars, the recommended tyre pressure is listed on a sticker inside the driver’s door. For some vehicles that have all the new mod-cons, the current pressure of each tyre can be displayed on the dashboard. It will warn you when you are over or under the recommended tyre pressure.

Low tyre pressure can make your car less fuel-efficient and impact the safety of your vehicle. Maintaining proper inflation is important to keep your tyres wearing evenly and improves their longevity.

If your vehicle is doing coast-to-coast drives over the interstates, or regularly going on unpaved roads, you should check the pressure more frequently.

What Causes Your Tyres to Lose Air?

Every car owner or fleet manager should aim to maintain proper tyre pressure. Knowing what causes tyre deflation can help you put preventative measures in place, to keep your tyres at the correct air pressure.

·      Movement of Air (Osmosis)

Osmosis of air through the tyres can lead to the loss of 1 to 3 PSI every month. The material and manufacture of the tyre impact the osmosis. This is as much as 10% of your tyre’s air pressure.

·      Slow Punctures

One of the most common causes of loss of air pressure is a slow puncture. A nail or other debris stuck in the tyre can cause it to lose 1 to 3 PSI every day. Often you won’t notice the puncture until there is significant deflation of your tyres, so it’s good practice to check your pressure regularly.

·      Impact Breaks

Hitting the curb or driving over large rocks or other objects on the road can cause sudden and excessive air loss. Impacts such as these will be noticeable almost immediately and you will need to call a roadside response like NRMA or RAC to come and fix or replace the tyre.

What Do the Experts Have to Say?

Most tyre and vehicle manufacturers give the same advice for having valve caps on your tyres. Bridgestone’s advice is typical of that from tyre manufacturers:

Valve caps are designed to keep water and dust particles out. Air will inevitably escape through the tyre rubber in all directions even with the valve caps in place. It is recommended to regularly inflate your tyres to ensure that they are at the right pressure and perform as they should.

In short, tyres will lose air pressure over time with or without a valve in place. However, the valve does help to retain air and does an important job of protecting the valve stem from dirt and moisture. Checking your tyre pressure regularly and ensuring your valve caps are securely in place are two ways you can ensure good tyre maintenance.

Tyre Myths

3 tyre myths that savvy Australian drivers ignore

Get value for money with these tyre tips

Australian drivers suffer from a common human condition, especially when it comes to tyres. We tend to think that we get more value from spending less. We also think that if we don’t use our tyres, they will last longer.

Are you really getting value for money when you buy new tyres?

If you are like most tyre buyers, you already have a budget in mind before you buy new tyres. But, is that set of new tyres in your budget really good value? Of course, being price conscious is necessary – especially when you are making an expensive investment such as buying a new set of tyres.

If you overspend or underspend on tyres, you’ll be making a big mistake either way.

Tyre Myth # 1: Cheaper tyres are better value for money

Cheap tyres are tempting, but are they a good investment? Generally, the mantra that you get what you pay for holds true. Tyres are not cheap to manufacture. It stands to reason that to make tyres more cheaply, a manufacturer probably uses inferior machinery and tooling, and lower-quality raw materials.

The saving you make when buying cheap tyres is usually a false economy. Sub-standard rubber wears faster. This means you will need to replace your new, cheap tyres sooner. You could find yourself buying two sets of cheap tyres for each set of premium tyres. In the long run, cheap tyres like this aren’t value for money.

Of course, this is not the only problem you are likely to suffer with cheap tyres. As the tyre tread wears, you’ll suffer with longer braking distances and poorer handling. Perhaps you don’t value your safety, or that of your passengers and other road users?

Tyre Myth #2: Expensive tyres are the best

Having read the myth about cheap tyres, you might think that the more you spend the better the tyres will be. This also isn’t true. If you have ever been to a restaurant and left thinking that you’d overspent, you’ll know exactly what I mean.

Just because a tyre is a brand name, doesn’t mean that the cost of the tyre represents good value for money. Some mid-priced tyres offer very similar quality and performance as their more expensive premium brand counterparts.

You don’t need to buy the most expensive tyres to get a quality product that offers safety and value for money.

Tyre myth #3: If you don’t use tyres they will last a lifetime

There are five considerations to make when you buy new tyres. These include your driving style and the road surfaces on which you usually drive. If you don’t drive many miles, and the miles you do drive are on smooth tarmac, your tyre tread is likely to remain deep and largely unaffected.

However, just because your tread looks robust and chunky, this does not mean that your tyres are safe to drive on. Tyres – even if they are not used – have a limited shelf life. Rubber breaks down naturally. You don’t need to damage your tyres by driving on them to own dangerous tyres.

Most tyre manufacturers recommend that you change your tyres at least every five years, irrespective of whether they have suffered wear and tear. (Learn how to tell the age of your tyres in our article “How do you know how old your tyres are and if they need replacing?”).

It’s not only age that can affect your tyres. Exposure to sunlight, heat, chemicals and fuel also affect a tyre’s useful life.

How do you buy tyres and make sure you get value for money?

The saying ‘buy cheap, buy twice’ usually applies when you buy tyres. However, if you are on a budget you may need to compromise on factors such as quality, warranty, tread, and so on. At our Darra Tyres shop, you’ll find qualified and highly experienced technicians on hand to help you make the best choice. We’ll ask you about your driving style, use, mileage, and the types of road you usually drive on. We’ll talk you through the different tyres available in your price range, explaining the pros and cons of each.

With Darra Tyres, you can be sure that you receive value for money at prices you can afford.
