How often do you worry about getting a flat tyre? Probably never, right? The thing is, nobody expects a puncture – yet it always happens at the worst time! Though some tyre damage requires a recovery, a tyre inflator might pump your tyre up enough to drive you to a nearby garage.
Inconvenient punctures aside, keeping correct tyre pressure is essential for your car’s overall health. Not only can It can improve fuel efficiency, it’s also vital for safety. This post will explain everything and recommend the best car tyre inflators for your money.
What Are Tyre Inflators, and How Do They Work?

Tyre inflators are portable, compact devices that pump air into your car or motorcycle tyres. Most use the 12V cigarette lighter socket in your car as a power source, and some digital tyre inflators automatically stop when the wheel reaches the desired pressure. A good tyre pump should have an accurate, easy-to-read digital display or pressure gauge.
Is It Worth Buying A Tyre Inflator?
Definitely. The biggest benefit of keeping a portable inflator in your car is always having access to a pump in an emergency. If it’s a slow puncture, you can simply blow up your car tyre in minutes instead of changing to a spare wheel or waiting for a recovery truck. However, there are some lesser-known benefits of owning one:
Enhanced Safety
Under-inflated tyres make a car difficult to handle and extend stopping distance. They also increase the risk of blowouts, as can over-inflated tyres, which can result in a serious accident. Maintaining optimal tyre pressure is safer for everyone.
Increased Fuel Efficiency
As your tyres lose air pressure, the contact area of the tyres increases, which means your engine must work harder to move the vehicle. Because it’s working harder, it burns more fuel. Ensuring your tyres are the correct pressure can reduce fuel consumption and save you money. Plus, they’re lighter than carrying power tools, jacks, or other garage equipment required for changing a tyre.
Increased Tyre Life
Another way to save money is by making your tyres last longer. When a vehicle tyre is rolling on the road, the tread part should make even contact with the road surface. So, if there’s not enough air inside the tyres, the softer outer edges to touch the tarmac and wear down faster, which will require you to change your tyres sooner. That said, you should check them regularly and replace damaged or worn tyres at once.

Frequently Asked Questions about Tyre Pressure
What is the correct tyre pressure for my car?
The correct tyre pressure varies depending on the size and weight of the vehicle. This value is usually agreed between the manufacturers of the car and the tyres that were originally fitted to it. Therefore, it is essential to follow this guidance for your own safety, and the safety of others.
Where can I find my tyre pressure?
There are a few places you might find your tyre pressure; a sticker inside the door sill, inside the fuel flap, or it may be in the vehicle handbook. If you can’t find it, you should contact the manufacturer or a local garage. However, sticking to around 31-32psi should be fine until you can find out for sure.
