Inflating the tire to the correct pressure is one of the most important factors when inflating the tire. Both underinflation and overinflation of tires can actually impair vehicle performance and tire life.

When a tire is overinflated, the air pressure inside the tire rises, and this increased pressure acts on the inner wall of the tire. This increase in pressure causes the inside of the tire to become stiffer than usual, which loses the tire's performance and, to some extent, affects the overall performance of the vehicle.

Overinflating a tire can cause the tire's sidewall and tread to stiffen. This reduces tire traction and performance and causes uneven tire wear. When the pressure increases beyond the recommended pressure, the tire's contact area actually decreases. The increased pressure causes the center of the tread to protrude more outward than the rest of the tire tread. This is a problem because traction in most tires these days only comes from the center of the tire, reducing the overall contact area of ​​the entire vehicle. This is also why an over-inflated tire will show signs of uneven wear in the center. Over-inflated tires will show signs of accelerated wear along the center because the center has more contact with the road than the outer edges. The reduced contact surface also leads to increased fuel consumption, as the engine now has to work harder to compensate for the reduced contact surface.

Over-inflating tires not only impairs the performance of the vehicle, but also reduces the comfort and safety of the vehicle. Over-inflated tires can also cause the vehicle to ride harder and less stable than properly inflated tires. The tire sidewalls are designed to support the vehicle and absorb some of the shock and bumps from the road surface as the vehicle travels on the road. When tires are overinflated, the sidewalls become stiffer, and instead of absorbing road bumps and shocks, they are transmitted directly to the vehicle's suspension. This can result in a more difficult ride, as well as increased noise. In severe cases, when dealing with older or severely overinflated tires, it is generally recommended to always inflate the tires on the vehicle to the pressure recommended by the tire manufacturer, and never to exceed the pressure limit indicated on the sidewall. Keeping the tires at the recommended pressure and rotating them regularly will ensure good performance and the longest lifespan of the tires.

The emergence of portable tire car tyre inflators provides a good solution for tire inflation. It is designed to be portable and practical. The built-in lithium battery allows the tire inflation pump to get rid of the shackles of the power cord. A car air pump can inflate an underinflated tire, but what if the tire is overinflated? Many car air pumps on the market may not provide the function of deflation, but the electric tire air pump with the wind is also designed with a deflation switch. When the tire is overcharged, just press and hold the deflation switch to deflate the tire. The wind car air pump can observe the tire pressure in real time through the digital display screen, so that you can clearly know the real-time tire pressure of the tire. When the tire reaches the recommended air pressure value, you can release the deflation switch. It is a good thing for car owners. A very nice utility tool.
