Is it necessary to replace tire pressure warning with tire pressure display?

Tire pressure display and tire pressure warning both serve driving safety, and both are good options, mainly depending on the driver's usage habits. Below are specific introductions about tire pressure display and tire pressure warning: The difference between tire pressure display and tire pressure warning: Tire pressure display allows for a direct view of tire pressure, while tire pressure warning is just an alarm system that alerts when the tire pressure is too high or too low. The hazards of abnormal tire pressure: Insufficient tire inflation pressure can lead to excessive tire wear, poor vehicle control, reduced fuel economy, and may also cause wheel deformation, so it is important to keep the tire inflation pressure within the specified range.
The tire pressure warning light only alerts you to a problem without specifying which tire is abnormal. I've experienced false alarms where I had to check each tire one by one after the warning, only to find out it was a false alert after much hassle. Switching to a tire pressure display is much more convenient, with real-time readings for all four wheels clearly showing, for example, the left front at 2.0 and the right rear at 2.8. On a previous long trip, I noticed the right front tire was slowly losing air, dropping from 2.5 to 1.9, allowing me to refill it in time and avoid a breakdown. During the rainy season in the south, road temperature fluctuations can cause a 0.3 bar difference between cold and hot tires, and the display function lets me monitor the actual tire pressure at all times.
From a technical perspective, tire pressure warning systems mostly use indirect monitoring, relying on wheel speed sensors to estimate pressure changes, while tire pressure display systems directly measure pressure with sensors installed on each valve stem. Previously, when my car had a slow leak from a nail puncture, the warning light only came on the third day, but the display showed the right rear tire pressure dropping from 250 to 205 kPa two days earlier. Having a tire pressure display also offers a hidden benefit: during inflation, you don't need to repeatedly check the pressure; just watch the value reach 250 kPa and you're done. It's normal for tire pressure to rise by 0.3 bar when driving on highways in summer, but beginners without numerical displays can easily misjudge this.
