Car Tyre Inflator Buying Guide

Old tyre inflators used to be a real pain to setup and were slow to inflate the tyres. However, the latest range of devices have overcome these issues with intuitive digital displays and extra functionality.

Driving with tyres that are not inflated to the correct PSI can cause abnormal tyre wear and handling issues. Keeping them inflated to the manufacturers specification is highly advised.

To help you make an informed buying decision, we have produced the below guide regarding tyre inflators.

Best Tyre Inflator

12V Socket vs Cordless vs Mains

Most manufacturers offer a range of portable tyre inflators that can be powered by different methods. The most common type is one that is powered by a 12V socket/cigarette lighter via a long power cord. They are usually the cheapest and come with a range of additional features.

Cordless powered alternatives are becoming more popular as you have the freedom of movement without the need to worry about wires. They come with a range of features but you must remember to keep the battery charged up.

The mains powered tyre inflator is the least common but is often the most powerful type, which can be extended via an extension cable.

Analogue vs Digital Display

The option between the classic analogue display with dials or the modern digital display is dependent upon your personal preference. Some people find it far easier to read dials with multiple unit readings at once rather than a digital display.

Using a digital tyre inflator is the most popular as it often comes with additional features. These include the ability to switch between units, automatic shut-off via preset values and much more.

Hose and Power Cord Length

There is nothing worse than the inflator not being able to reach all four wheels from the 12V socket. If you own a large vehicle, you will want to check that the hose and power cord length is long enough to avoid disappointment.


Due to the improvement in car tyre inflator technology, there is plenty of automated features built into the devices. The automatic shut-off is one of the best features as it stops the inflation process once it reaches a pre-set pressure. This prevents over inflating your tyres and allows you to do something else whilst waiting for the tyre to inflate.

Inflation Time

Depending upon the power of the compressor will depend upon the amount of time it takes to inflate a tyre. Some manufacturers state the amount of time it may take but many may not work with large tyres used on 4×4’s or trucks.

What Tyre Pressure?

The tyre pressure that you should use for your car will be specified by the manufacturer. As you can see in the image below, the pressure should reflect upon the weight in the car and the tyres that are used. You will be able to find the correct tyre pressures for your car by checking the user manual, side of the drives door or in the fuel filler cap.

Portable Design and Storage

Most tyre inflators will weigh less than 2KG but this doesn’t mean that they will be easy to store and carry around. You will want to ensure that the portable tyre inflator you choose has an ergonomic handle that is easy to grip.

Another important factor is the size because you will want to be able to store it inside the car or within the garage.

Pressure Units

As shown in the image above, there are many units used to measure pressure. The most commonly used in PSI but others include bar and KG/CM2. The majority of premium tyre inflators will allow you to switch between different units to suit your requirements.

If you are unable to switch the unit, you can use a calculator to determine the correct tyre pressure for your car.

Price and Warranty

The cheaper tyre inflators may seem tempting but we advise purchasing those with extra features and adapters. The automatic shut-off is a desirable feature that is found in most premium options and we highly recommend. You should also consider the warranty as many cheaper alternatives may not provide any whatsoever, which could be an issue.


Ensuring that you have the correct tyre pressures is vital before any journey. Thanks to modern technology, most modern vehicles are fitted with tyre pressure monitoring system to notify us straight away. This means that as soon as you receive an error message, you can instantly correct the pressure with a tyre inflator.

All of the recommendations above are suited to a range of budgets and can be powered by a variety of methods. The AA state that you should check your tyres every week to ensure they are correctly inflated. Investing into one of the recommendations in this article make this task much easier.
