What Causes the Tire Pressure Light to Keep Flashing?

[SanOlive]

Here are the reasons why the tire pressure light keeps flashing: 1. The tire pressure monitoring light may illuminate due to a punctured tire, which usually causes a very slow air leak. In such cases, it might be difficult to immediately identify which tire is affected. You can use a tire pressure gauge to measure the pressure. If the tire is underinflated, inflate it to the proper level and then observe the tire pressure warning light. 2. Sometimes, the tire pressure monitoring light comes on due to overinflation. According to international standards, the recommended inflation pressure for passenger car tires is as follows: standard tires: 2.4 to 2.5 bar; reinforced tires: 2.8 to 2.9 bar; maximum pressure should not exceed 3.5 bar. 3. The tire pressure monitoring light may also illuminate after prolonged driving with low tire pressure. This usually occurs when one tire is significantly underinflated, causing the tire temperature to rise during high-speed driving, which in turn increases the tire pressure. In such cases, you should stop and rest or replace the tire with a spare one as soon as possible.
