Tyre Pressure Gauge

Different types of tyre pressure gauges have different uses, but they can be broadly divided into two types.

One is a handheld digital tyre pressure gauge with a battery, which does not have a tyre inflation function. To use this type of tyre pressure gauge, you only need to gently press the "ON/UNIT/OFF" button to turn it on, select the desired range, and press firmly onto the valve to get an accurate reading displayed instantly on the backlit LCD. The gauge automatically resets and turns off after 30-40 seconds to save power.

Another is a tyre pressure gauge with an inflator, straight locking chuck, gauge, hose, and bleed valve, all in one unit with functions for deflation, inflation, and tyre pressure checking. To use this type of digital tyre pressure gauge, connect it to the air compressor and screw the air chuck onto the tyre valve. Press the valve controller to inflate the tyre to the desired pressure displayed on the backlit LCD screen. The gauge is accurate within 1% and has a display resolution of 0.1 PSI.

Please choose the best tyre pressure gauge that meets your needs, but consider the following essential factors:

Firstly, ensure the gauge covers the pressure range needed for your vehicle. AstroAI tyre gauges cover a broad range, typically up to 250 PSI, making them suitable for various vehicles. For specific information, please refer to the detailed description on the product page.

Secondly, decide between digital, analogue, or stick pressure gauges. Digital tyre pressure gauges provide readings on an LCD screen, making them incredibly easy to read. Analogue gauges display the pressure reading on a dial face and are known for their durability and ability to function without batteries. Stick pressure gauges are simple, compact, and resemble a pen in design. They are mechanical and do not require batteries, but can be slightly less accurate than analogue or digital gauges and may be more difficult to read.

Thirdly, the most critical aspect to consider is accuracy. AstroAI gauges often have a precision of ±1%, ensuring reliable readings. At the same time, ease of use is also important. Can it be used with one hand? Does it fit comfortably in your hand? Is the pressure reading easy to read? Our digital pressure gauges typically feature a non-slip texture, making them easy to hold, and their ergonomic design suits both men's and women's hands.

Finally, check for extra features like backlit displays, large buttons, and inflation or deflation functions that make the gauge more user-friendly.

For accurate tyre pressure readings, follow these steps:

1. Press the gauge firmly onto the tyre valve. A proper seal ensures accurate readings.

2. For digital gauges, check the display. For analogue gauges, observe the needle's position. Repeat the process to confirm consistency.

3. Ensure the gauge is perpendicular to the valve stem for accurate readings.

Maintaining the correct tyre pressure is crucial for safety. Here are some signs that your car tyres may be over-inflated:

Reduced Traction: Excessive pressure reduces the tyre's contact patch with the road, decreasing grip.

Poor Traction: Over-inflation reduces the contact area between the tyre tread and the road surface, resulting in decreased grip. This may cause the wheels to slip in wet conditions, such as on rainy days.

Reduced Vehicle Control: You may find it harder to control your vehicle, especially at higher speeds. The steering may feel lighter or more sensitive than usual, which is a sign of reduced stability. Your vehicle may react unpredictably to steering inputs, increasing the risk of losing control.

What You Should Do to Avoid These Situations:

Always refer to your vehicle manual for recommended tyre pressure, which is typically between 30-35 PSI for most passenger vehicles. Check tyre pressure regularly using the AstroAI tyre pressure gauge and make sure your car's tyre pressure is within this range. Note that you should check tyre pressure when the tyre is cool, as driving will heat up the tyre and temporarily increase pressure.
