Top 10 Best Tire Pressure Gauge to Buy in 2021
While tire health is underestimated by many car owners, it is actually very important to keep your car’s tires properly inflated to get the optimum performance: a smoother ride, quicker steering and braking response, better handling, better fuel economy, safety, and longer tire lifespan. Monitoring your tires is a simple task you should do once a month. For only $5 to $20, you can get the best tire pressure gauge that will provide you with reliable service for many years to come.
This ultimate guide will provide helpful explanations on the benefits of tire pressure gauges, the different types of tire pressure gauge, a list of the very best tire pressure gauge for each type, plus pro tips on using and maintaining this handy tool.
What Does a Tire Pressure Gauge Do?
Keeping your car tires properly inflated is an easy maintenance task and one that would not cost you a ton of money.
Under-inflated tires will lead to excessive tire wear and worse, can result in premature tire failure.In addition, they also reduce fuel economy. They will not do their best at bearing and distributing the weight of the car, thus will negatively impact the vehicle’s braking and handling.
Maintain optimal tire pressure at all times will resolve the above issues.It is important to remember that the “appropriate” tire pressure level depends on the make and model of your car and many other factors. Consult your owner’s manual to find out the right tire pressure level that you should maintain.
A tire pressure gauge will give an accurate reading of the current pressure inside each tire, so you can monitor and adjust the pressure to achieve optimal pressure level easily.
Tire-pressure gauges are available at auto-parts stores, big-box stores, and other retailers, as well as online. For typically $5 to $15, you can already get a good gauge.
Why You Need a Tire Pressure Gauge
A tire gauge is not just a purchase. It is an investment that you will come to appreciate more and more down the road thanks to the important benefits it provides for your precious vehicle:
Maintaining appropriate inflation will ensure your car will not need to work extra hard to make up for under-inflated tires, which impedes your vehicle from achieving the speed it should.
There’s no need to explain why you will enjoy a smoother ride and enhanced stability if all four tires on your car are at the same level of pressure, and the correct one at that. Maintaining a uniform and appropriate tire pressure also put less strain on the rest of your vehicle.
Less Tire Wear & Replacement
Under-inflation means larger tires contact with the road surface and excess heat, resulting in excessive tire wear. Simple spending under $20 for the best tire pressure gauge to keep your tires in good shape and avoid premature replacement is therefore a wise decision.
Your tire pressure and your braking experience are directly related. The more under-inflated your tires are, the longer stopping distance whenever you slam on the brake pedal. Therefore, maintaining proper tire pressure at all times is a good safety practice.

Types Of Tire Pressure Gauge
Each of the different types of tire pressure gauge has its benefits. The key is to choose one you are comfortable using and find easy to read, and of course suits your budget.
Buy a gauge with a wide-enough range that it can measure the pressure in a temporary spare, which is typically 60 psi. The majority of gauges on the market have a span of 5 to 100 psi.
If you need to check pressure in a darkened area, like in your garage, a digital gauge with an illuminated display would be the most convenient.
Stick gauges are the cheapest type, at an average price of just under $5. Stick-type gauges somewhat resemble a ballpoint pen. They are simple, compact, and affordable, however they are a little harder to interpret than most digital gauges.
Since a tire pressure gauge is a tool you will reach for regularly in the long term, you might want to spend just about $10 extra to get the best tire pressure gauge with more user friendly display, either a digital or a dial one.
Digital gauges are generally very accurate and easy to read. Digital gauges cost about $10-$12, on average, more than stick gauges but still a minimal long term investment.
Digital gauges have an electronic LCD display, like a pocket calculator, making them easy to read. Some digital readouts light up, making them handy for checking pressure in dark conditions. They’re also more resistant to damage from dust and dirt compared to stick gauges.
A minor downside is that digital gauges are a little larger than stick gauges and they require batteries. While batteries can last for years, they will of course need replacement. This is however not a major inconvenience.
They can also be bulky and typically cost more money, running from $20 to $50. The average cost is around $25, which is still reasonable for what they can offer you in any years to come.
Dial gauges have an analog dial, resembling a clock face, with a simple needle to indicate the pressure. Most dial gauges are easy to read.
While some dial gauges have extra features, including an extension hose, bleeder valve, dual-scale dial, and shock-resistant dial cover, they aren’t necessarily more accurate and you would not really need them.

Bonus: Tire Pressure 101
Nearly all tires lose pressure gradually over time, even if the car isn’t driven and the tire is only sitting there in storage or is mounted on the car as a spare.
With a tire that is undamaged and properly mounted on the rim, most of the pressure loss comes from air escaping through the rubber sidewall, not through the inflation valve. The valve stem’s dust cap is to keep dirt out, not air in.
What affects tire pressure
Tire pressure drops as the weather gets colder, since cold air is more dense. A typical car tire measured at 30 psi during 80-degree temperatures will return a reading of 25 psi when the temperature drops to 30 degrees.
The air pressure within a tire is almost unaffected by the weight of the car. An unmounted tire inflated to 32 psi will still measure nearly the same when it’s mounted and bearing the weight of the car.
Tire pressure gauge maintenance
A note on maintenance of your tire pressure gauge is to keep your gauge at room temperature, as very hot or cold temperatures can impact performance. Avoid keeping it in the glove box.
Proper tire pressure
When checking and adding air to your tires, follow the automaker’s recommended pressure setting, which is usually found in your owner’s manual and also located on a placard or sticker on the driver’s-side door or inside the glove compartment or fuel-filler door.
This recommended pressure provides the best combination of performance, ride comfort, service life, and fuel economy.
Do not go by the “max pressure” number found on the tire sidewall. This is the maximum amount of pressure that the particular tire can withstand without damage and thus is not a safe operational pressure level.
How to Check and Adjust Tire Pressure
Follow this step-by-step guide to check your car’s tire pressure in just a few minutes:
- First, find out what the recommended pressure setting is for your car. Typical inflation pressures range from 28 to 36 psi. The recommended front- and rear-tire pressure may differ.
- For an accurate read, make sure the car has been parked for three or more hours before checking the tire pressure.
- Check each tire by first removing the screw-off cap from each tire’s inflation valve. Be careful not to lose the caps, as they protect the valves.
- Insert the end of the tire-pressure gauge into the valve and depress it. If you hear air escaping from the valve, push the gauge in further until it stops.
- View the pressure reading. If the pressure is correct, simply retighten the valve cap.
- Don’t forget to check the pressure of the spare tire when the time comes that you need to put it to use. Spares often have high inflation pressures, typically 60 psi.
