Are you the proud owner of a Lexus RX 350? If yes, try to make it perform its best to give you an enjoyable ride. And knowing Lexus RX 350 tire pressure is one of the first things to check now.
Tire pressure affects your car’s performance, fuel efficiency, and tire lifespan. Hence, keeping it in check is a must. However, the task may be more complicated than expected.
You will need this article to maintain and monitor Lexus RX 350 tire pressure properly. Let’s scroll down to learn!
What Is The Recommended Lexus RX 350 Tire Pressure?
The recommended tire pressure for Lexus RX 350 depends on the specific model year, trim, and original tire size.
| Model Year | Tire Size | Front Tire Pressure | Rear Tire Pressure |
| 2007 to 2009 | 225/65R17 101S | 30 PSI | 30 PSI |
| P235/55R18 99V | 30 PSI | 30 PSI | |
| 2010 to 2015 | P235/55R19 101V | 32 PSI | 32 PSI |
| P235/60R18 102V | 32 PSI | 32 PSI | |
| 2016 to 2022 | 235/55R20 102V | 33 PSI | 33 PSI |
| 235/65R18 106V | 33 PSI | 33 PSI |
You can get to know the exact inflation info of your Lexus RX 350 by checking the owner’s manual or the specs listed on the sticker in the door jamb.
The recommended tire pressure varies depending on the car’s manufacturer, tire size, and tire type. Sometimes, the rear and front tires of the same car demand different pressure levels.
The sidewall of the tire is another place that saves RX 350 tire pressure info. In the case of full loading capacity, it reveals the max inflation.
Regular Recommended Pressure Vs. Winter Pressure
The recommended tire pressure for all cars is around 30 to 35 PSI. If you use the Lexus RX 350, it should be 33 PSI in most cases.
The tire may explode if you increase the pressure from 10 to 20% above the recommended range. And then, you will risk your comfort and safety.
However, the recommended PSI for winter is different. As a general rule, it should be 3 to 5 PSI higher.
Dealing with the tires is the best tip for handling winter conditions. For example, Honda Civics can still run on the snow thanks to their snow tires .
Besides, all-terrain vehicles often feature deeper and more aggressive treads with softer compounds. These qualities allow them to travel across wintry conditions safely.
Similarly, in the winter, traction and grip are the most important things. Increasing the pressure in your car tires will improve their stability, reducing the responsive steering.
With that thought in mind, Lexus RX 350 tire pressure winter should be around 36 PSI. If the conditions worsen, you can go up to 38 PSI.
Why Should You Maintain The Recommended Lexus RX 350 Tire Pressure?
Proper tire pressure is essential for the efficiency and safety of your Lexus RX 350. The following reasons will help you understand its significance.
Safety
Overinflated tires may reduce grip and cause excessive wear. On the other hand, underinflated tires lead to poor handling, longer stopping distances, and tire breakdown.
All of those consequences come from tires with improper pressure. They will put you at risk when driving, especially under harsh conditions.
Fuel efficiency
If you give your tires adequate pressure, they can improve fuel efficiency by minimizing rolling resistance. The cost of gas and carbon footprint will also decrease significantly.
Tire lifespan
Your tires can last longer with proper tire pressure. It’s because underinflated tires suffer from uneven wear and will break down faster. The only solution here is to replace the tires.
How To Check Lexus RX 350 Tire Pressure?
Checking the tire pressure on your Lexus RX 350 is essential for your safety and fuel efficiency. But how to do it properly?
First, you need an air compressor and a digital or pencil gauge. Then, follow these steps:
- Find the valve cap on the tire and remove it. Remember to keep it in a secure place.
- Firmly push the valve stem with the pressure gauge. Once the tire’s air goes out, you can hear a hissing noise.
- The pencil gauge has a little bar with etched digits. The bar now pops out due to air pressure so that you can check the pressure level on the gauge. Meanwhile, the PSI reading will appear on the display when you use a digital meter.
- To achieve a tight seal, directly push the air compressor into the valve stem lever. Then, hold the nozzle against the air valve for a while.
- Perform step 2 again to take another gauge reading of the PSI.
- Use a tire inflator to release or add some air so that your tire can reach the recommended pressure.
- Refill the stem cap.
- Repeat these steps with the other tires.
Regularly checking your tire pressure is advisable. You should do it once per month or before a long drive.
If you have any reason to suspect a tire’s pressure has become low, check it, too. The TPMS (Tire Pressure Monitoring System) light may inform you of this issue.
Aside from the TPMS light, other signs will indicate the low-pressure tires are poor performance, strange steering, and rough riding.
How To Reset The TPMS Light On Lexus RX 350?
The TPMS light helps you monitor your tire’s condition. However, after checking and refilling the tire based on what the Lexus RX 350 tire pressure light recommends, the light remains lit sometimes.
In this case, you need to reset it. The method is different, depending on the model year of your car.
If you drive a Lexus RX 350 made before 2016, the instructions for resetting the TPMS light are as follows:
- Ensure that all the tires are at cold pressure with your car turned off.
- Turn on your vehicle but do not start its engine.
- Find the TPMS reset button near the steering wheel. It’s in the “set” state now.
- Press and hold the button until you see a few light flashes.
- Leave your automobile there for a while so the system can recalibrate.
If you have a Lexus RX 350 manufactured since 2016, here is how to reset its TPMS light:
- Adjust the tires to their correct tire pressure when your car is still off.
- Turn the car on, and leave the engine inactive.
- Use the navigation buttons on the dash display to open the “vehicle settings” panel.
- Press the OK button.
- Choose TPMS.
- Press the OK button until the TPMS light flashes three times.
- Drive for a short distance to give the system time to calibrate.
If these methods don’t work, try stopping your car, turning off the engine, and turning it on again. Then, the TPMS light may stay off and start to blink again.
If none of these helps, you might have a Lexus RX 350 tire pressure sensor issue. In this scenario, take your car to a mechanic to thoroughly look into it.
How Long Can Lexus RX 350 Tires Last?
The tire lifespan of a Lexus RX 350 might differ depending on various factors, including driving style, road conditions, weather, and tire maintenance.
The average tire lifespan for the Lexus RX 350 is between 50,000 and 60,000 miles. In other words, you can use them for about three to five years.
Regular maintenance will extend the tire’s lifespan. Some common practices are:
- Checking the tire pressure often
- Rotating and balancing the tire when needed
- Ensuring proper alignment all the time
Conclusion
We hope this article has given you all you want about Lexus RX 350 tire pressure. Mostly, your car needs 33 PSI pressure in the tires. However, you should check your specific model to get the exact answer.
Tires roll to keep your car running. Once they have any problems, you and your automobile will suffer. Hence, in addition to the recommended tire pressure, remember to perform other maintenance procedures to protect the tires.
