Knowing the correct tire pressure for your 2022 Subaru WRX is fairly straightforward—it is 33 psi for the front tires and 32 psi for the rear tires for all trim levels.
The Subaru is a sedan for the high-performance vehicle lover that’s willing to sacrifice a little bit of comfort and refinement in exchange for a sporty driving experience. Whatever you use it for, keeping up maintenance on your WRX is going to be important—especially when it comes to tire pressure.
Here’s an overview of what you need to know about your WRX’s tire pressure and how to reset the TPMS (tire pressure monitoring system).
What is the right tire pressure for a Subaru WRX?
Subaru makes it quite simple: for the front tires of the latest WRX, the tire pressure is 33 psi. For the rear tires, it’s 32 psi. This is true for all four trim levels: the base, Premium, Limited, and GT.
Conveniently, this is true for all model years of the WRX going all the way back to 2013. Any trim that you have in any model year will be 33 psi for the front tires and 32 psi for the rear tires.
Tire pressure recommendations for other Subaru vehicles
If you own other Subaru vehicles, the metrics will be a little different. Here’s a quick breakdown of the tire pressures for the most popular makes:
Vehicle | Front tire pressure | Rear tire pressure |
|---|---|---|
2022 Ascent | 35 psi | 35 psi |
2022 BRZ | 35 psi | 35 psi |
2022 Crosstrek | 33 psi | 32 psi |
2022 WRX STI | 33 psi | 32 psi |
2022 Outback | 35 psi | 33 psi |
2022 Legacy | 33 psi | 32 psi |

All you need to check your tire pressure is a trusty air pressure gauge. This can be small enough to fit in your pocket or your car’s glove box and can be handy when it comes to releasing air from your tires as well.
To get a reading, just press the gauge into your tire’s valve stem (after removing the valve stem cap). You can also go to a nearby filling station or use a portable tire inflator if it’s equipped with a gauge if you don’t have one on hand.
If any of your tires are over or under-inflated, just add or release air as needed. If you want to double-check what your recommended pressure is, just look for a tire pressure information label, usually located on your WRX’s driver’s-side door frame.
Your WRX’s display will also have a display that displays the pressures of all four tires. If any of your tires are underinflated, the value will be illuminated in yellow.
As an added safety feature, the WRX also has a tire pressure warning light that may turn on if a tire is underinflated—if this happens, calmly pull over to a safe location and do a pressure check to correct as needed.
How often should you check tire pressure?
Subaru recommends checking tire pressure at least once a month and any time before you go on a long road trip. Make sure to include the spare tire in your checks as well.
You should only check the pressure when the tires are cold. Tires are considered cold when your vehicle has been driven for less than a mile or parked for at least three hours.
Temperature can affect your tire pressure as well. So, if you adjust tire pressures in a warm garage and drive outside in cold weather, the warning light may illuminate due to the resulting drop in pressures outside. To avoid this problem, Subaru says you should inflate your tires by an extra 1 psi for every difference of 10°F between the indoor and outdoor temperatures.
How to tell if your Subaru WRX needs new tires
Each one of your tires has a tread wear indicator, which will become visible as the depth of the tire’s tread grooves decreases to 0.063 inches. As soon as this indicator becomes visible, you should replace your tire immediately.
Regardless of treadwear, tires will degrade with age, so manufacturers often recommend replacing tires every six to ten years, or at least getting them inspected at similar intervals.
How to reset the Subaru WRX tire pressure monitoring system (TPMS) light
Tire pressures are “read” by the WRX’s Tire Pressure Monitoring System (TPMS). This system does not function when the vehicle is stationary, so you may notice that your low pressure warning light stays on even if you’ve already corrected the pressure in all your tires. In this case, your TPMS simply has not had time to recheck tire inflation pressure.
Subaru suggests increasing the vehicle speed to at least 20 mph for the TPMS to start rechecking pressures. Once this happens, the pressure warning lights should turn off.
If this still doesn’t fix the issue, you may need to
get your TPMS reset
. Older cars often come outfitted with a TPMS reset button under the steering wheel that you can use to reset your TPMS—your owners manual should tell you how to do this.However, the standalone WRX, which was first released in 2013, does not have this option. To reset the TPMS service, you’ll need to buy a TPMS tool and OBD II module to perform what is a relatively complicated procedure. At this point, the best option would probably be to take your WRX to an authorized dealer or discount tire shop for them to reset your system for you.
