Correctly adjusted tire pressure is the foundation for safe and economical driving on a crossover. Nissan Murano. Many owners mistakenly believe that a visual inspection is enough, but modern inspection systems TPMS require exact numbers specified by the manufacturer. Ignoring this parameter leads to accelerated tire wear, increased fuel consumption and, in the worst case, loss of control on slippery roads.
Each generation of the model Murano has its own nuances related to the size of the rims and suspension characteristics. Standard values can vary from 2.2 to 2.6 atmospheres depending on the season and vehicle load. In this article, we will analyze not only the standard values, but also show how to independently reset the sensor error if, after pumping, the lamp on the instrument panel continues to light.
Determining the optimal pressure for your Nissan Murano
Manufacturer Nissan places a sticker with current data in the driver's door opening or on the inside of the gas tank flap. It is these numbers, and not the values stamped on the sidewall of the tire, that are the only correct ones for your specific car. The sidewall always indicates the maximum pressure that the tires can withstand, and not the pressure at which the car will drive comfortably and safely.
For most crossover versions Murano with factory R17 or R18 wheels, the recommended reading is 2.2 to 2.4 atmospheres (32-35 PSI) when cold. If you are planning a long trip with a full load of passengers and luggage, the pressure in the rear axle must be increased to 2.6 atmospheres. This will prevent overheating of the rubber and deformation of the tire carcass during intense driving on the highway.
- 🚗 Summer mode: 2.2–2.4 atm for standard load.
- ❄️ Winter mode: 2.3–2.5 atm, taking into account air compression in cold weather.
- 🎒 Full load: 2.6 ATM in the rear wheels for stability.
⚠️ Attention: Pressure measurements should only be carried out on cold tires. After a trip longer than 2 km or driving at a speed above 50 km/h, the air temperature inside the wheel increases, and the pressure gauge readings will be overestimated by 0.2–0.3 atmospheres.
The effect of incorrect pressure on vehicle performance
A decrease in pressure by only 10% of the norm leads to a noticeable deterioration in acceleration dynamics and an increase in fuel consumption by 3-5%. Massive body Nissan Murano requires rigid support, and flat tires create enormous rolling resistance. The ECU tries to compensate for the loss of power by increasing fuel delivery, which directly impacts your budget.
Excessive pressure, on the contrary, makes the suspension too stiff and reduces the contact patch of the tire with the road. This is especially critical in rainy weather, when the car needs to effectively drain water from under the wheels. Overinflated rubber acts like a ball, springs up and loses grip, which increases the braking distance and the risk of aquaplaning.
Incorrect road contact geometry also leads to uneven tread wear. At low pressure, the shoulder areas are erased, and at high pressure, the central part is erased. Replacing a set of tires is expensive, so regularly checking pressure is a way to save significant money in the future.

Procedure for measuring and setting pressure
For accurate measurements, use a high-quality mechanical or digital pressure gauge, as readings at gas stations often have an error. Find the wheel nipple, clean it of dirt and press the device tightly. An audible whistling sound indicates a poor fit and incorrect data, so the procedure should be repeated.
If you use a compressor, do so in short bursts while constantly checking the pressure gauge. Once the desired value is reached, tighten the nipple cap to prevent moisture and dust from entering the camera. In winter, be sure to check the pressure at above-zero temperatures in a warm box or garage, since the air outside may be too cold for an accurate measurement.
- 🛠️ Tools: Pressure gauge, compressor, nipple wrench.
- 🌡️ Conditions: Cold tires, smooth surface, clean nipples.
- ⏱️ Frequency: At least once a month and before each long trip.
☑️ Wheel check
TPMS system operation and error reset
Pressure control system TPMS (Tire Pressure Monitoring System) in Nissan Murano uses sensors built into the wheels. They transmit a signal to the on-board computer. If you have inflated your tires to the correct level but the warning light remains on, you will need to perform a reset procedure. Often the system does not update data immediately after swapping and requires initiation through the menu.
To reset the error, go to the car settings through the multimedia system or instrument cluster. Find an item Vehicle Settings or Tire Pressure Monitor and select the reset command. After this, drive the car at a speed above 40 km/h for 10-15 minutes so that the sensors transmit new data to the central module.
In some cases, especially after changing wheels or repairing a tire, the sensors may not respond immediately. This may be due to a low battery in the sensor itself or the need to retrain the system. If a standard reset does not help, you should contact a service to diagnose the condition of the sensors.
Where is the TPMS reset button?
On most Nissan Murano models, the reset button is located under the steering column on the left. On newer models, the reset is carried out through the multimedia system menu: Settings -> Vehicle -> Tire pressure monitoring system -> Reset.
⚠️ Attention: If after resetting the error returns after a few days, most likely one of the tires has a slow air leak or the pressure sensor itself is faulty. Do not ignore this signal and check the tightness of the wheels.
Specifics of operation in different weather conditions
The physics of air is such that when the temperature drops by 10 degrees Celsius, the pressure in the tire drops by about 0.1 atmosphere. In winter, when the temperature jumps sharply, the system TPMS may trigger falsely. That is why in winter it is recommended to keep the pressure 0.1–0.2 atmospheres higher than summer values in order to compensate for losses during night cooling.
In the summer, when driving on hot asphalt, the air inside the tire expands. If you overinflate your tires on the track, when you brake hard or enter a turn, this can lead to the destruction of the tire carcass. The optimal strategy is to check the pressure in the morning, when the car is parked in the shade, and not exceed the norm by more than 0.2 atmospheres.
For crossover Nissan Murano With all-wheel drive, it is critical to maintain equal pressure in all four wheels. A difference of even 0.3 atmospheres can cause the all-wheel drive clutch to work in extreme mode, overheat and fail. Transmission manufacturers strictly monitor this parameter.
In winter, keep a table with standards on hand. If you see a pressure light on the screen immediately after leaving a warm parking lot in the cold, do not rush to go to the gas station. Let the wheels sit outside for 15-20 minutes so that they cool down to a realistic temperature, and only then measure the pressure.
Table of recommended values for Murano generations
Below is a summary table that is relevant for most modifications Nissan Murano (II and III generations). Remember that the final decision should always be made based on the data on your specific vehicle's sticker, as the factory may have installed a different tire size.
| Tire size | Front axle (atm) | Rear axle (atm) | Spare wheel (atm) |
|---|---|---|---|
| 235/65 R17 | 2.2 | 2.2 | 4.2 |
| 235/60 R18 | 2.3 | 2.3 | 4.2 |
| 255/50 R20 | 2.4 | 2.4 | 4.2 |
| Full load | 2.4 | 2.6 | 4.2 |
Pay attention to the high pressure in the spare tire. It is usually temporary (re-rolling) or has a smaller diameter, so it requires significantly more rigid inflation to compensate for the weight of the car. Using the spare tire for a long time at low pressure is unacceptable.
A monthly pressure check is not just a formality, but a critical procedure for preserving suspension life, saving fuel and ensuring the safety of passengers in your Nissan Murano.
Frequently asked questions from Nissan Murano owners
Crossover owners often face ambiguous situations related to pressure. Below we have collected answers to the most popular questions that will help you avoid mistakes when operating your car.
Why does the pressure light come on after winter if I recently changed the tires?
Most likely, the TPMS sensors were damaged during installation or discharged during the winter storage season. It is also possible that when changing disks, sensors from a different model were used or the procedure for pairing them with the control unit was not carried out.
Is it possible to drive a Nissan Murano with a pressure of 2.0 atm if the car is empty?
Technically the car will move, but this is not recommended. At 2.0 atm, the sidewall of the tire will be greatly deformed in corners, which will worsen handling and can lead to overheating and destruction of the rubber during sharp maneuvers. The optimal minimum is 2.2 atm.
Do you need to relieve pressure before going to the mountains?
No, you don't need to relieve pressure. On the contrary, as you rise to a height and the tires heat up, the pressure increases. If you climb mountains with low pressure, the risk of your tires overheating increases. Follow the manufacturer's standard recommendations for summer use.
How to understand that the pressure sensor has failed?
If, when checking with a pressure gauge, the pressure in all wheels is normal (for example, 2.3 atm), and a warning is on on the dashboard, and resetting through the menu does not help, most likely one of the sensors is faulty. Also, the sensor may “die” if the car has been standing motionless for a long time (more than a year).
Does pressure affect the operation of the all-wheel drive system?
Yes, critically. The difference in wheel diameter due to different pressures forces the all-wheel drive clutch to constantly work, trying to synchronize the speed of rotation of the axles. This leads to overheating and premature wear of the expensive unit. Always keep the pressure the same.
