Acura RDX Tire Pressure

Are you about to inflate your Acura RDX tires and wonder what the sweet spot is for the PSI for both front and rear tires?

You can save yourself the hassle and confirm the exact recommended amount from your owner’s manual or the tire specification label sticker attached to the door frame on the driver’s side.

However, according to the automaker, the general recommended tire pressure for an Acura RDX vehicle is between 32 to 32 PSI for both the front and rear tires.

Meanwhile, Acura RDX is offered in different trim levels of the RDX (the A-Spec and A-Spec Advance, for example) have varying standard tire sizes than the base RDX trim.

Also, you will need to reconsider (or compromise) the tire pressure of your Acura when working with touring or winter tires.

So, they will all have different tire pressure needs, despite the ballpark recommendation.

And that’s why I have done the homework for you and put this list together, showing you the recommended tire pressure for the sports crossover SUV based on the model year, tire size, and trim model.

How To Know The Best Tire Pressure For Your Acura

The recommended tire pressure for Acura vehicles is similar regarding their compact luxury crossover SUV lineups.

But when in doubt, you can know the factory-recommended tire pressure for your Acura by checking your owner’s manual. Alternatively, the information is printed on the sticker attached to the inside of the driver’s door.

Now, here’s the tricky part.

The recommended PSI amount listed on the sticker label is cold tire pressure.

So, if you see that the automaker recommends that the air pressure in the tires be in the 32 to 35 range.

You should inflate with additional 3 psi when adding air to compensate for the cold tire pressure. As you probably know, extreme weather conditions can directly affect tire pressure.

I also recommend you keep an eye on your tires as you drive, using the TPMS sensor.

What Happens When You Drive An Acura Rdx On Low Tire Pressure?

Driving on low tire pressure, below the recommended PSI range for your Acura RDX, will likely cause increased fuel consumption and reduced tread life of your tires.

But, if you aren’t lucky, it doesn’t end there.

Driving on low tire pressure will result in decreased traction and longer stopping times. Under-inflated tires could also cause the tire to fail, which deters your driving experience.

So when you notice that your TPMS light is on, it is a sign that your tires are losing pressure, and you shouldn’t ignore it.

Why Is My Acura Rdx Tire Pressure Light Flashing?

All Acura RDX year models, starting from 2008, are equipped with the tire pressure monitoring system. When this sensor flashes on your dashboard, it signifies that you must fix your tire pressure. Your tires may be under-inflated or over-inflated at that point.

If you checked the tires and nothing seemed wrong, the flashing TPMS light indicates another issue.

In many situations, it is linked to battery replacement needs since the tire pressure sensors need the battery to work properly.

If you checked the battery and nothing seems to be wrong, it means the sensor itself is malfunctioning, either due to temperature changes or requires a reset.

At that point, I recommend you take your Acura RDX to tire maintenance to diagnose the problem.

How To Turn Off The Tire Pressure Light On Acura Rdx

I mentioned earlier that the tire pressure light comes on when your tires are overinflated or underinflated. But sometimes, even after you’ve taken care of that, you may still see the tire pressure light flash on your dashboard while driving.

This is a common issue for most Acura compact SUVs, and the solution is to reset the sensor. But before attempting that, try driving above 50 mph for at least 10 minutes, then turn it off. When you turn it on, the light should be reset.

Otherwise, it would help if you used the TPMS reset button.

Step 1: Turn the key to the “on” position, but don’t start the vehicle.

Step 2: Press and hold the TPMS reset button. Release it when the light blinks three times.

Step 3: Release the button and drive the car for 20 minutes.

The system should then be reset by now.

Another possible solution is to inflate all tires to over 3 PSI above the recommended tire pressure amount. Then, deflate the tires before filling them back to the correct amount.

Before turning on the vehicle, disconnect the positive battery terminal, and press the horn for at least three seconds. Then, reconnect the battery.

At this point, the Tire pressure light should work properly. If not, then I recommend you visit the tire maintenance store to have expert technicians probe into the issue.

Wrapping Up

As a crossover offered in 8 trims and equipped with 4 original equipment tire size sets, Acura RDX has slightly different tire pressure for their year models as it varies by model year, model trim, or its original equipment tire size.

Generally speaking, the recommended tire pressure is between 32 psi to 36 psi across the 2007 to 2021 model years.

But I recommend you double-check your vehicle specification.
