rehvirõhuks

rehvirõhuks is an Estonian term that translates to "tire pressure" in English. It refers to the amount of air inside a pneumatic tire. Maintaining proper tire pressure is crucial for several reasons, including safety, fuel efficiency, and tire longevity.

When tires are underinflated, they can overheat, increasing the risk of a blowout. Underinflated tires also lead to increased rolling resistance, which means the engine has to work harder to move the vehicle, resulting in lower fuel economy. Furthermore, uneven wear patterns can develop on the tire surface, shortening its lifespan.

Overinflated tires can also be problematic. They reduce the tire's contact patch with the road, which can negatively impact traction and braking performance, especially in wet conditions. Overinflated tires are also more susceptible to damage from impacts, such as hitting potholes.

Vehicle manufacturers specify the recommended tire pressure for their models, typically found on a sticker located on the driver's side doorjamb, in the owner's manual, or on the fuel filler door. This recommended pressure is usually for the front and rear tires, and it may differ. It's important to check tire pressure regularly, ideally when the tires are cold, as driving heats them up, increasing the internal pressure. Using a reliable tire pressure gauge is essential for accurate readings.
