This is the article for you if you’re looking at tire pressure gauges. This guide is a great place to start. You will get great insights into the Lexus Rx 350 tire pressure and what is ideal for different driving conditions.


The recommended tire pressure on your Lexus Rx 350 has changed over the years. It is more to do with the year of your car model and the trim on the vehicle. Depending on the driving conditions, the recommended Lexus Rx 350 tire pressure varies between 30 psi and 33 psi.

As mentioned earlier, the recommended psi depends on your car model and its rims.


What Is the Benefit of Checking Your Lexus Rx 350 Tire Pressure?

If you’re a Lexus RX 350 owner, then you probably value your car’s safety above all else. So, naturally, you want to ensure that your tires are correctly inflated – the only way to ensure that is by knowing the recommended psi level.

But why should you check them? Well, there are a lot of reasons. For one thing, checking your tire pressure will let you know whether or not your tires will last longer. If they’re low, it could indicate that something isn’t right with the tire itself (like a leak). However, if it’s too high, it could result in decreased traction. It will also increase the wear and tear of the tire.

The last thing anyone wants is to be involved in any accident or mishap. That’s why this simple task of checking your tire pressure should be done regularly.


What Psi Is Recommended for the Lexus RX350?

As mentioned above, the recommended PSI for Lexus RX350 is between 30 and 33 psi. The below table will help you understand everything about different Rx350 models and their recommended psi.

Tire Size Year Front Tire Rear Tire
225/65R17 2007-2009 30 psi 30 psi
235/55R20 2016-2022 33 psi 33 psi
235/65R18 2016-2022 33 psi 33 psi
P235/55R18 2007-2009 30 psi 30 psi
P235/55R19 2010-2015 32 psi 32 psi
P235/60R18 2010-2015 32 psi 32 psi

What Does Psi Mean?

The psi is a measure of the pressure inside the tire, and it’s often represented by a number. It stands for pound per square inch. The higher the number, the greater the pressure.

The psi in your tires keeps them from exploding when you go over potholes or drive over rough terrain. If your tires are under-inflated, the tire could explode due to overheating.


Does the Tire Pressure Differ Based on Weather Conditions?

Yes, the tire pressure varies based on weather conditions. When driving in dry conditions, your tires are under less pressure than when driving in wet or icy conditions. This is because the weight of moisture in the air causes a tire’s internal pressure to decrease.

When it comes to driving in dry conditions, it is essential to maintain adequate tire pressure so that your vehicle can handle the increased weight of water and other substances that may be present on the road.

While it may seem counterintuitive, maintaining proper tire pressure will help keep you safe on the road and save you money over time.


Do Your Tires Lose Psi in Cold Weather?

Tire pressure is a critical component of driving safety. The pressure in your tires can affect how your car handles, the efficiency of its engine, and how long it takes to get from point A to point B.

However, other factors affect tire pressure, including temperature, age, and weight of the vehicle you’re driving. The same goes for your tires: if they’re cold, they’ll lose psi faster than normal.

The reason for this is that lower temperatures affect your tire pressure. This is due to the low density of air. In simple words, the air outside your tires is less dense due to cold weather. This makes them lose psi faster.


How Often Should You Check Your Tire Pressure?

Although it’s best to check your tire pressure at least once a month, you should do so more frequently if you notice any changes in the condition of your tires or road conditions.

Under-inflated tires can be harder to handle and provide less traction than properly inflated ones. This can lead to accidents, reduced fuel efficiency, increased wear on your vehicle, and increased wear on the wheels themselves.

There are several ways to keep a check on your tires:

  • Take a close look at the side of your tire. If there is any sign of wear or damage, such as dents or cracks in the sidewall, it’s time to change. 
  • You may also want to invest in a quality pressure gauge so you can check your tires’ pressure quickly without having to visit a gas station whenever you want to know whether they’re adequately inflated!
  • Keep an eye out for leaks by checking underneath each tire every week or two and ensuring none have deteriorated since the last check. 



Several drivers have reported tire blowouts and wrecks after not checking the pressure of their tires regularly. So, to counter this tendency, a pressure gauge can be a lifesaver. It’s one of the most essential Lexus accessories to keep you safe on the road.

Just make sure to check the air pressure in your tires twice a month or before every long trip. This simple task could keep you and your family out of harm’s way.
