Rehvirõhumõõtjad

Rehvirõhumõõtjad, also known as tire pressure gauges, are devices used to measure the air pressure inside pneumatic tires. Maintaining correct tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity. Incorrect tire pressure can lead to uneven tire wear, reduced handling, and an increased risk of blowouts.

There are several types of rehvirõhumõõtjad. Analog gauges typically have a dial with a needle that indicates the pressure. Digital gauges use an electronic sensor and display the pressure numerically on an LCD screen. Pencil gauges are small, portable, and often come as a keychain accessory. More advanced systems include Tire Pressure Monitoring Systems (TPMS) integrated into the vehicle's electronics, which provide real-time pressure readings and alerts.

Using a rehvirõhumõõtja is straightforward. The cap is removed from the tire valve, and the gauge is firmly pressed onto the valve stem. The pressure reading is then observed. It is recommended to check tire pressure when the tires are cold, meaning the vehicle has not been driven for at least three hours, as driving heats up the tires and increases the internal pressure, leading to an inaccurate reading.

The recommended tire pressure for a specific vehicle is usually found on a sticker inside the driver's side doorjamb, in the owner's manual, or sometimes on the fuel filler door. It is important to adhere to these recommended pressures, as they are set by the vehicle manufacturer to ensure optimal performance and safety. Regularly checking tire pressure with a rehvirõhumõõtja is a simple yet effective maintenance task for any vehicle owner.
