What Does Left rr Tire Low Mean? Tips for Addressing Low Tire Pressure
There are four different signs indicating four different tires on most cars or other vehicles. These signs are used to describe various situations of tires regarding their pressure.
The Left rr tire low means the left rear tire of a vehicle is under-inflated. So, if you notice this sign on the dashboard of TPMS, it is basically saying that the air pressure of the left rear tire is not sufficient and you should increase the pressure as soon as possible.
This article is all about these signs. Besides, I’ll also discuss what to do when you see these. So, let’s start.
What does left rr tire low meaning or indicate?
The left rear tire low means the tire pressure in the left rear wheel, which is basically the left-back wheel of a vehicle, is low in pressure.
In modern vehicles, there is a TPMS module that indicates the pressure condition in each tire. The sensor is inside the rim and it continuously collects and sends data to the ECU.
Whenever it senses any severe fluctuations in pressure, it gives a warning to the dashboard. For the left rear wheel, the sign is “Left rr”. If you observe this sign, check the left rear wheel, and possibly you’ll find that the tire is under-inflated.
What are all the signs of TPMS?
There are many other similar signs like Left FRT tire, Right rr tire, etc. Each of these has a specific meaning and is necessary to understand.
In a four-wheel vehicle, the wheels at the frontal side are called front wheels. These are indicated as Right FRT for the passenger side and Left FRT for drivers side.
For the back side of the vehicle, the wheels for the left and right are called Left rr and Right rr respectively. If any of these four warning signs appear on the dashboard of TPMS, this means the corresponding tire is low on pressure.
All you need to do is to increase the pressure. But remember, sometimes the TPMS can show the wrong warning sign and you may get confused. So, it is recommended to check the pressure manually before taking any steps.
If this happens, calibrating TPMS can solve the issue. Later in this article, you’ll see how to do it properly to overcome the issue.
What to do when the left rr tire is low?
If the left rear tire is low on pressure, the first thing to do is to check it with a pressure gauge. This will make sure that the warning is correct and you need to increase the pressure.
In this situation, if you’re driving, stop the car immediately and park it in a safe zone. Then inflate the tire to its optimum pressure level. Then check whether the warning sign is gone or not.
If still the sign is ON, then probably the pressure is not the main reason behind this warning. Rather, a faulty sensor, damaged TPMS or wrong calibration can cause the sign to come up.
Well, don’t worry, just keep reading. The following part will describe how to overcome this type of situation too.
Pressure is okay but TPMS show the left rr tire low – what’s the issue?
Often an anomaly can be seen in the TPMS when the tire pressure is absolutely fine, still, the TPMS can show the left rr tire low sign. This is mainly the problem of TPMS calibration.
In that case, resetting TPMS can solve the problem. All you have to do is to start the car and drive it at a minimum speed of 50 mph for about 30 minutes to an hour.
Then the next time you start the car, most probably you won’t see the sign and the problem will be solved. Another popular method is to deflate the tire completely and then re-inflate it. This will also reset the TPMS.
right rr tire low related FAQ
Any wheel at the back of the vehicle is called a rear wheel.
Yes. Left side is the driver side whereas the right side is the passenger side.
In most cases, you’ll see the position of the tire is mentioned on the tire sidewall. It can be an arrow sign or simply written on the tire.
Verdict
Left rr tire low indicates the insufficient pressure of air inside the left back wheel. This is a very basic sign of the TPMS module.
If you face these types of problems, immediate action should be taken. Otherwise, the under-inflated tire can cause severe wear and tear of the tires. Not only that, but it can also affect the control as well as the braking system.
So, increase the air pressure to the optimum value if you see this issue. If this doesn’t solve the problem, consult with a mechanic as soon as possible.
