If you’ve ever had a blowout during a road trip, you’ll know first hand how important it is for vehicle owners to own a tyre pressure gauge. This is a basic part of vehicle maintenance, and we’ve all occasionally dipped over to the gas-station compressor, and topped up the pressure.
It’s well known that checking the pressure in your car tyres is important, but what you may not realize is that pressure gauges are even more important for cyclists. Did you know that bike tyres are often filled to a higher pressure than the ones in your car? This means that, under certain conditions, they can be more likely to blow. When you have a blowout on a vehicle, you’ve still got three wheels to steer you to the side of the road. But on a bike, there is nothing to fall back on. Improperly pressurized tires can put you in harms way.
Fortunately, mountain bike tyres don’t require specialized gauges. Accuracy is of a little more importance, but automotive and cycling gauges are mostly interchangeable. This means that if you buy a good tyre gauge, you can use it for both your vehicle and your bike. It also means that they’re widely available.
What Types of Pressure Gauges are Out There?
There are three different types of pressure gauges on the market. Each has their own set of advantages and disadvantages, although certain types are in more widespread use than others.
Dial gauges were, historically, the most accurate models you can buy. They resemble a pen with a small clock on the top. You place them on your tyre, and the dial rotates to indicate the pressure. You’ll find a lot of high-end dial gauges on the market, many of which include accessories such as an extension hose, multi-unit scales, and a bleed valve so you can drop your tyre pressure.
These stick type gauges are what most people think of when they imagine a tyre pressure gauge. Place the inlet on your tyre, and a stick slides out. Like a ruler, it measures the pressure in your tyre. These are cheap to produce and readily available, but have a limited span and are somewhat inaccurate.
As the most modern and powerful gauges on the market, these are often our first choice. They use a compact, single-line LCD display, much like that of a calculator. The pressure is calculated by a digital sensor, which provides a higher level of accuracy than mechanical sensors. These gauges are often a little bulkier and require batteries, but they are our number one choice.
Why Choose Digital?
There are two key advantages to a digital gauge: accuracy, and range. Although dial indicators are often promoted as being much more accurate than rod types, this is simply not the case. When you’re reading an analog gauge, there is only so much accuracy you can get.
Your eye will never read it perfectly, and the gauge will wear out over time. But digital gauges won’t fade out of calibration over time, and they provide the highest level of accuracy possible. Additionally, you’ll be able to use your gauge for both your bike and your car tyres, so you only need to make a single purchase.
In this roundup, we’ll be taking a look at the 5 best digital tyre pressure gauges on the market. We’ll show you our top picks to find out what they have to offer. After, we’ll help you decide which one is right for your needs.
What You Need to Know About Tyre Pressure
A common misconception is that you simply throw a little air in your tyres, give em a squeeze, and ride off. If you fill them too much, or too litte, your ride quality can be negatively impacted. Additionally, your pressure will change throughout the day, depending on how you’re using your bike.
The two most important factors in tyre pressure are temperature and volume. Your pressure will change with the weather. When it’s hot, your pressure increases. When it’s cool, it decreases. Friction also factors into this.
If you’re riding downhill through rough mountainous terrain, the additional friction will warm up your tires, and increase the pressure. Have you ever noticed that your bike feels a little bouncier after ripping down a dirt hill? The cause is most likely friction and temperature.
The volume of your tyre is also an important factor. The larger the tyres, the less pressure you need.
- Road bikes are typically inflated to a pressure between 125 PSI and 75 PSI, as they have very thin and compact rubber.
- Mountain bike tyres, on the other hand, should be inflated to around 30 PSI. Larger and more aggressive models may have an even lower pressure.
- Hybrid tyres average 60 PSI, but this depends heavily on the model.
The exact specifications will be found on your tyre, but this general guideline should give you an idea of what you need out of a digital tyre pressure gauge.

Knowing your tyre pressure is only half the battle. If your measurement is out, then it’s time to bust out the pump. If you’re sick of manually pumping your bike tyres, why not find an automated way to do so. If this is something you’re interested in, the best deal on the market is the PI Auto Premium Digital Tyre Inflator.
This unit combines the functionality of a digital pressure gauge and a DC compressor all in one. Just plug the compressor into the AUX outlet of your vehicle, and use the simple controls to set your desired pressure. At the touch of a button, this compressor will automatically inflate your tyres until they’ve hit the correct pressure, then shut off the compressor. This tyre inflator is extremely fast and surprisingly powerful. But that doesn’t come at the expense of precision. You can fill a bike tyre with an accuracy of 1 PSI, which is acceptable for almost all users.
The inflator comes with a free set of valve caps, as well as replacement presta valves. Consumers who’ve upgraded to presta valves know how frustrating it is to be caught with a damaged valve, so having an extra one on hand is nice to have.
How to Use Your Digital Pressure Gauge
Before you can select a gauge, you need to understand how to use it. Different gauges are suited for different purposes, and there are several different ways to use them depending on how you like to ride.
First, let’s go over the basics. To accurately measure pressure, you need to first remove the cap from the valve stem. You then press the gauge inlet down over the valve stem. You may hear a hissing sound. It’s important to press down hard enough that you don’t hear any hissing. When air is escaping, the pressure is artificially low – so you won’t get an accurate reading. But once the sound has stopped, you’ll have a proper seal and the displayed measurement should remain stable.
You’ll also need to decide when to check your tyre pressure. There are two types of measurements you can take: a cold measurement, and a warm one. This has nothing to do with the weather, but more to do with how recently you’ve been using your bike.
You should take a cold measurement once per week. If you’ve recently ridden the bike, it should be left to cool off for at least one hour before taking a measurement. If there is any discrepancy between the pressure your bike tyres are rated for and the actual pressure, this is when you fill it.
A warm measurement should be taken while you’re riding. Let’s say, for example, you’re tearing your mountain bike down a rough path. Your tyres will warm up, and the pressure will increase. You might notice that your ride feels a little hard, indicating that the pressure is too high. Or, you might notice that your tyres and squishy, and don’t have as much traction as they should. This could indicate a low tyre, or not enough pressure.
Warm measurements will tell you how much to fill your tyres next time you top them off. If you’re always 2 PSI too high, you can fill them 2 PSI below their recommended pressure. Some riders also choose to keep their pressure artificially low, or artificially high to get your desired riding style. Taking warm measurements will help you understand how pressure changes when in use, so you’ll know what to apply at the pump to get the desired fill.
Which Bike Tyre Pressure Gauge is Right for Me?
Not sure which one to choose? There are a lot of different options out there, and each of them has their own sets of advantages and disadvantages. But before you choose one, you’ll need to understand how to use them, and what you’re hoping to get out of your pressure gauge.
