Will a Car Pass Inspection With Tire Pressure Light On

A car’s tire pressure is very important and should be checked regularly. If your car’s tire pressure is low, it could cause a number of problems, including decreased fuel efficiency, increased chance of getting a blowout, and even possible damage to the vehicle. In this article, we’ll show you how to check your car’s tire pressure using a simple and easy method.

What is the Tire Pressure Light and What Does it Mean?

The Tire Pressure Light is a warning light on many cars that tells drivers when the air pressure in their tires is low. The light will turn on when the tire pressure falls below the recommended level, and it will stay on until the tire pressure is back to the recommended level.

When the light comes on, drivers should check their tire pressure as soon as possible. If the pressure is too low, they can bring it up to the recommended level by using a compressor or by inflating their tires using a car air pump. Depending on the make and model of their car, drivers may also be able to adjust the air pressure manually.

How to Check Tire Pressure

If you are like most drivers, you check your tire pressure at least once a week. And if your car has a tire pressure warning light on, you probably check it more often. But is checking tire pressure really necessary? And what do the different symbols on your dashboard mean?

In short, checking tire pressure is important for two reasons: safety and emissions. Underinflation can lead to unsafe driving conditions, and overinflation can cause your car to lose fuel efficiency. Plus, when your tires are underinflated, they can become unstable in the event of a crash.

To check your tire pressure, first make sure you have a reliable gauge. Chances are good that your car comes with one – many modern vehicles have an air pressure sensor built into the system. If not, you can buy a gauge off of Amazon or another online retailer.

Once you have your gauge, find the correct PSI reading on the gauge using these steps:

Step 1: Park your car in a level spot with all four wheels firmly on the ground. Don’t use ramps or tools to press down on the tires – this could change their psi readings.

When Should You Replace a Tread?

When should you replace a tire? This question is asked by drivers all over the country. In order to answer this question, it is important to understand when the tread on a tire is worn out. The National Highway Traffic Safety Administration (NHTSA) states that when the tread depth on a tire is less than 1/8 inch, it is time to replace the tire. When the tread depth is less than 3/16 inch, it is time to replace the tire. And finally, when the tread depth is less than 1/4 inch, it is time to replace the tire.


If your car has a tire pressure light on, it is important to know that the inspection process will not be completed until the light is turned off. The reason for this is that inspectors are looking for signs of wear and tear on the tires, which can only be detected by measuring their pressure. If you have a low tire pressure, it might be better to wait until the light goes out before visiting your mechanic to get them checked because there could be other problems with your car that would need his attention first.
