The proper 2015 Nissan Altima tire pressure is essential for safe handling, good fuel economy, and preventing excessive tire wear. With the right tire inflation, you’ll maximize the life of your Nissan Altima’s tires and keep repair costs low.
This guide will walk you through the recommended tire pressures for the 2015 Altima along with steps to accurately measure and adjust air pressure. We’ll also cover tips for maintaining optimal 2015 nissan altima tire pressure over time.
Let’s get started!

If you just need the official tire pressure recommendation without the extra details, here it is:
33 PSI for all standard tires on 2015 Nissan Altima models
However, keep reading to understand why this number matters and how to dial in the exact pressure for your tires.
Recommended Tire Pressure for 2015 Nissan Altima
The 2015 Nissan Altima came equipped with the following standard tire sizes from the factory:
- 215/55R17 94V
- 235/45R18 94V
Nissan recommends keeping all four tires inflated to 33 PSI (pounds per square inch) on Altima models with either tire size.
This guidance comes directly from the placard located on the driver’s side door jamb. You can verify it matches what’s printed on your 2015 Altima’s placard.
The figure is valid for both front and rear tires. You should not adjust pressure based on a tire’s position.
Furthermore, the recommendation holds whether your Altima has a full load of cargo and passengers or you’re driving solo. Unlike some vehicles, Nissan says Altima tire pressures do not need adjustment for different loads.
So in nearly all cases, target 33 PSI in each standard 2015 Nissan Altima tire for peak performance and tread life.
Deviating too far above or below 33 PSI can negatively impact handling, braking distances, and fuel mileage. Over the long run, incorrect pressures rapidly degrade tires as well.
Now let’s go over the processes for measuring current pressure and reaching the correct 33 PSI target.
Checking the 2015 Nissan Altima Tire Pressure
You’ll need an accurate tire pressure gauge to check inflation levels. I recommend a digital one for precision.
Analog gauges with arms and dials are prone to giving faulty readings that could have you adjusting pressures unnecessarily.
Here are the proper steps to check the 2015 Nissan Altima tire pressure:
- Make sure the tires are cold – Meaning the car hasn’t been driven for more than a couple of miles recently. Warmer tire temperatures lead to falsely high-pressure readings.
- Remove the valve stem cap from the first tire.
- Firmly press and hold the gauge head on the valve stem for several seconds.
- The gauge will display a PSI reading – note whether it matches the recommendation.
- Repeat the process to grab the pressures of the other three tires. Be thorough for the most accurate average.
- Verify all four tires are reasonably close to the 33 PSI target.
- Make adjustments using the steps below if any individual reading falls outside of 29-37 PSI.
I suggest repeating this sequence at least monthly to catch pressure drops early. Additionally, check out tires when they seem underinflated or you suspect slow leaks.
Catching issues promptly leads to fewer flat tires and longer-lasting treads. But sometimes pressures drop rapidly from punctures or cracked seals – so stay vigilant.
Adjusting The 2015 Nissan Altima Tire Pressure
When tires significantly deviate from the recommendation, you’ll need to add or release air accordingly.
To add air:
Locate the low tire(s) using the gauge per the instructions above. Then drive to a gas station or shop with an air compressor station. These pump air straight from the hose – allowing you to dial in the precise PSI you want.
Attach the compressor hose nozzle firmly over the tire valve stem. Then activate the station to start airflow. Watch the PSI gauge on the pump rise to your target number.
To release excess air:
You’ll need a special tire valve core tool along with the tire gauge.
First, verify the accurate pressure using your gauge. Then use the valve tool to briefly depress and open the valve’s internal seal. This will begin slowly releasing air – lower the pressure incrementally while continually rechecking with the gauge.
Stop when you’ve removed enough air volume to get back down to 33 PSI.
Regardless of adding or removing air, you want to triple-check all tires with your gauge once finished. Confirm each reads correctly at the 33 PSI mark before driving away.
Tire Pressure Monitoring System
As an added form of oversight, the 2015 Nissan Altima features a tire pressure monitoring system (TPMS).
Here are some key facts about how it works:
- Each wheel contains a wireless pressure sensor that transmits readings to the car’s computer.
- Dash indicator light illuminates if any tire drops 25% below the target inflation (roughly 25 PSI).
- You can also see pressure readings via the trip computer display when traveling above 15 MPH.
- TPMS sensors have small batteries inside – Nissan recommends replacing them roughly every 5 years.
- The system provides backup oversight but is no replacement for using your gauge manually. The readings can have lags in detection or accuracy.
While TPMS has benefits, stay proactive with your monthly pressure checks using a gauge. This gives the most reliable data to prevent problems.
Maintaining Proper 2015 Nissan Altima Tire Pressure
Inflation levels inevitably reduce slowly over time – even in perfectly sealed tires. Why does this air loss occur?
Mainly through permeation, which is the gradual passage of pressurized air molecules through micropores in the rubber. The natural outgassing occurs faster as ambient temperatures rise.
Therefore it’s critical to verify pressures at least monthly to counteract the inevitable leakage. This ensures any developing issues get caught early before tires underinflate excessively.
You also need to remain observant while driving for symptoms of underinflation:
- Steering feeling loose or vague
- Sluggish turn-in response
- Major decrease in fuel economy
- Uneven tire tread wear
- Visible “cupping” tread patterns
If you spot these warning signs, safely pull over when possible to check pressures immediately using the steps above.
Finally, I suggest investing in metal valve stem caps with rubber gaskets instead of plastic caps. The metal construction resists cracking from heat cycles and tightening while providing optimal seals against air seepage.
They only cost a couple of dollars per cap yet will maintain pressure better between checks – saving you refill trips over time.
Buying your digital tire gauge is another wise investment – enabling accurate monitoring without reliance on shops or complex TPMS systems.
Next Steps
Understanding and practicing the proper 2015 Nissan Altima tire pressure habits outlined here will keep your ride safe while helping tires last up to their full tread lifespan.
It only takes a few minutes per month plus occasional topping off or releasing overages as needed. These quick checks pay dividends through enhanced vehicle handling, boosted fuel efficiency, and prevention of blowouts or accidents.
Be sure to memorize the key specifications of 33 PSI for all standard Altima tires. Verify this matches your door jamb sticker just for reference.
Empower yourself to measure and adjust using the techniques above rather than ignoring pressures month after month. Developing good TPMS habits now will carry over seamlessly as you own future vehicles too.
Thanks for reading – here’s to maximizing the potential of your 2015 Nissan Altima!
