Whether it is necessary to install an external tire pressure monitoring system depends on the actual situation. External sensors are easy to install, but their long-term performance is not ideal. They are suitable for car owners who plan to change vehicles in the short term, as they are inexpensive and do not require professional installation, lasting for a few years without issues. The differences between external and internal tire pressure monitoring systems are as follows: 1. Price difference: Internal systems are relatively more expensive than external ones. 2. Installation method and time required: Installing an internal tire pressure monitoring system takes more time and requires professional assistance to remove the tires, making it difficult for individuals to install on their own. In contrast, external systems are simpler to install, allowing car owners to do it themselves. 3. Accuracy difference: Due to environmental and external force factors, external systems are slightly less accurate than internal ones. 4. Anti-theft difference: Internal systems are more secure because they are installed inside the tires, making theft nearly impossible unless the entire tire is stolen. External systems have poorer anti-theft performance since the same brand's sensors often use the same removal tools, making it easy to remove sensors of the same brand.

After installing an external tire pressure monitoring system, I found it extremely necessary, especially for friends with less-than-ideal daily driving habits. My last flat tire was caused by excessively low tire pressure, costing me over a thousand yuan in repairs, not to mention the safety hazards. This device clamps directly onto the valve stem, displays real-time pressure, and alerts immediately if the pressure is too low or too high, helping me avoid several potential issues. It's not expensive, just a few hundred yuan, and easy to install yourself. With proper tire pressure while driving, tire wear becomes more even, extending tire life and saving about 5% on fuel costs. Although some worry about theft or weather affecting accuracy, I haven't encountered such issues. Overall, for driving safety and cost-effectiveness, installing one is definitely worthwhile—don't wait until an accident happens to regret it.

As a young person who frequently drives long distances, I think an external tire pressure monitoring system is totally worth installing. After all, the point of driving is convenience and peace of mind. This device connects to your phone via an app, providing real-time pressure updates and alerting you immediately if anything's abnormal—no need to stop and check manually every time. Installation is a no-brainer too; just screw it on. From experience, it's helped me prevent flat tires and reduced the risk of blowouts on highways by more than half. The downsides are occasional accuracy fluctuations or the risk of theft, but overall, its functionality is practical. Considering the convenience and safety it offers, especially for those who often drive on highways or carry passengers, there's no reason to hesitate. The savings on fuel and tire costs alone make it pay for itself.

Regarding external tire pressure monitoring systems, my opinion is to carefully evaluate before installation and avoid blindly following the trend. The advantages include providing real-time tire pressure information, helping prevent blowouts and tire overheating accidents. However, there are several drawbacks: improper installation may cause air leakage, the device accuracy can sometimes be unreliable, especially in areas with significant temperature fluctuations; they are also prone to theft or damage to the valve. In comparison, built-in systems are more stable but several times more expensive. From a personal vehicle usage perspective, if you only drive short distances in urban areas, the necessity is low; but for long-distance travel or frequent heavy loads, installation is recommended. Ultimately, the decision should be based on your driving habits.
