Understanding what wheel size provided by the manufacturer and is safety critical. In this article we will analyze all the nuances: from standard diameters to permissible deviations. You will learn how the choice of profile affects ground clearance and why balancing is important.
Factory specifications and standard sizes
Manufacturer Nissan for the Z50 model, several configuration options are provided, which directly affects the diameter of the disks. In basic versions, 17-inch alloy wheels are most often found, while top trim levels are equipped with 18- or even 19-inch options. Each size has its own specific width and reach parameters.
The standard disc width for most versions is 7.0 inches, which provides sufficient contact patch area for confident traction. However, in some markets you can find wider 7.5J wheels that require a corresponding tire width. It is important to consider that changing the width of the rim without changing the offset can lead to friction against the arches.
Wheel offset (ET) is a critical parameter that is often ignored when purchasing aftermarket tires. For Nissan Murano Z50 The factory offset is usually ET45 or ET47. A deviation upward or downward of more than 3-4 mm can lead to accelerated wear of the wheel bearings.
- 💎 Standard wheel diameters: 17, 18 and 19 inches.
- 💎Rim width: mostly 7.0J.
- 💎 Bolt pattern (PCD): 5x114.3.
- 💎 Central hole diameter (CH): 66.1 mm.
Tire selection: size tables and profile
Choosing the right tire profile is just as important as choosing the wheel diameter. The low profile improves handling, but makes the suspension stiffer and more vulnerable to potholes. A high profile, on the contrary, increases comfort, but can worsen steering response when cornering. For crossover Nissan Murano Manufacturers recommend balancing between these factors.
Below is a table of the most common tire sizes that are ideal for stock Z50 wheels. Please note that changing the tire size may affect the speedometer reading and the operation of the ESP stability control systems.
| Disc diameter | Tire size (width/profile) | Overall wheel height | Seasonal recommendation |
|---|---|---|---|
| 17 inches | 235/65 R17 | 705 mm | Winter / All season |
| 17 inches | 235/60 R17 | 680 mm | Summer |
| 18 inches | 235/55 R18 | 687 mm | Summer/Winter |
| 19 inches | 255/45 R19 | 692 mm | Summer |
When replacing tires with a size different from the factory one, it is necessary to monitor the overall height of the wheel. The difference should not exceed 2-3% of the standard value. Otherwise, the electronic control unit may generate errors, and the vehicle's ground clearance will change in an unpredictable way.
Tire pressure and its impact on operation
Correct tire pressure is not just a recommendation, but a necessity to preserve suspension life and save fuel. For Nissan Murano Z50 recommended values depend on vehicle load and season. Typically, pressure information is located on a sticker inside the driver's door or in the gas filler flap.
In summer, with normal loading, it is enough to maintain the pressure at 2.2-2.3 atmospheres. If you are planning a long trip with a full cabin of passengers and luggage, the pressure should be increased to 2.4-2.5 atmospheres. This will prevent the tires from overheating and sidewall deformation.
In winter the situation changes dramatically. At low temperatures, tire pressure drops, so it must be increased by 0.1-0.2 atmospheres relative to summer values. However, you should not overinflate your tires, as this reduces the contact area with the road and impairs traction on ice.
⚠️ Warning: Using tires with incorrect pressure can cause uneven tread wear and even cause the tire to burst when hitting an obstacle at high speed.
- ❄️ In winter: check the pressure when the tires are cold (after parking for more than 3 hours).
- ❄️ In summer: check your blood pressure every 2-3 weeks, especially in the heat.
- ❄️ Full load: be sure to increase the pressure to the maximum indicated on the nameplate.
- 17 inches
- 18 inches
- 19 inches

Features of installing winter tires and wheels
Many owners Nissan Murano prefer to have two sets of wheels: summer and winter. This makes seasonal changes much easier and keeps things balanced. For winter, wheels with a smaller diameter (for example, 17 inches) are often chosen in order to install a higher profile tire. This increases comfort and reduces the risk of damage to the disc when falling into a hole.
When choosing winter tires for a crossover, it is important to consider the type of tread. The Scandinavian type with sharp checkers is better suited for harsh winters and ice, while the European type with an asymmetrical pattern is effective on wet asphalt and slush. For a city with clean asphalt and rare snowfalls, a European design is also suitable.
The mounting bolts or nuts must match the type of disc. Alloy wheels require tapered or spherical bolts with the correct thread pitch. The use of bolts from stamped steel wheels on cast wheels (and vice versa) is unacceptable, as this can lead to loosening of the wheel.
☑️ Preparing for the winter season
You should not use it as the main wheel for long distances, especially in winter conditions when traction is critical.
Is it possible to install discs of a different diameter?
Yes, you can, but with restrictions. The main condition is maintaining the overall height of the wheel. If you are using 18-size wheels instead of 17-sizes, the tire profile must be smaller so that the overall wheel diameter remains the same (within 3%). Otherwise, problems may arise with the speedometer and ground clearance.-->
Technical nuances
bolts, spacers and alignment
When replacing wheels, the question often arises about the need to use spacers. Spacers may be required if you are installing lower offset (ET) wheels to prevent the wheel from rubbing against the suspension components. However, excessive use of spacers increases the stress on the wheel bearings and suspension arms.
For Nissan Murano Z50 The standard diameter of the central hole is 66.1 mm. If you buy universal disks with a large center of gravity, be sure to use adapter rings (centering rings). Without them, the wheel will be centered on the bolts, which will cause the steering wheel to wobble at high speeds and body vibration.
Wheel bolts must be of high quality and comply with the strength class. Often, when purchasing non-original wheels, the supplied bolts are too short or have the wrong head shape. This may result in the wheel not being pressed against the hub with the required force.
- 🔧 Use only original or certified bolts with the correct taper angle.
- 🔧 Centering rings are required when installing discs with a CO > 66.1 mm.
- 🔧 Spacers should not exceed 5-7 mm without reinforcing the suspension.
⚠️ Attention: Improper tightening of wheel bolts can lead to them unscrewing while driving or breakage of the hub studs. Always use a torque wrench.
The influence of wheel size on vehicle performance
An increase in wheel diameter inevitably affects the vehicle's dynamics. Larger, lower-profile discs provide sharper steering and improved handling at high speeds. However, this comes at the expense of comfort: the suspension becomes stiffer, and vibrations from the road surface are transmitted more strongly to the body.
On the other hand, installing smaller diameter wheels with a higher profile increases ground clearance and makes the ride smoother. This is especially true for Russian roads with their uneven surfaces. But it is worth considering that too high a profile can lead to a “floating” steering wheel and a slow response to steering wheel turns.
It is also worth remembering the effect of wheel weight on fuel consumption and acceleration dynamics. Lightweight wheels reduce unsprung weight, which has a positive effect on suspension performance and reduces engine load. Heavy wheels can increase fuel consumption by 3-5% and worsen acceleration.
The balance between comfort and handling depends on your preferences: 17-18 inches for comfort and maneuverability, 19 inches for dynamics and aesthetics.
If you plan to install custom-sized wheels, be sure to take a test drive or consult with specialists. An incorrectly selected size can not only spoil the driving experience, but also lead to premature failure of suspension components.
Frequent errors during selection and operation
One of the most common mistakes is ignoring the load index and speed on the tire sidewall. For Nissan Murano Z50 the load index must be at least 103 (for 17-18 inches) or 104 (for 19 inches). Using tires with an underrated index can lead to the tire bursting under load.
Another mistake is mixing tires of different models or different tread patterns on the same axle. This upsets the balance of braking and handling, which is especially dangerous on slippery roads. All four wheels must be identical in characteristics.
Sometimes owners try to save money by buying used discs with deformations. Even microcracks invisible to the eye can cause destruction of the disk at the first serious load. Always check disk geometry before installation.
- 🚫 Do not mix tires of different models and patterns on the same axle.
- 🚫 Avoid buying damaged used rims without checking the geometry.
- 🚫 Do not ignore load and speed indices when buying tires.
Following these simple rules will help you avoid accidents and extend the life of your car. A properly selected wheel is the key to safety and comfort in any driving situation.
Use "rocking" (back and forth) with care to avoid damaging the transmission. If you have snow chains, use them. Do not spin the wheel while slipping at high speed, this may cause the differential to overheat.-->
What is the maximum tire size for the Nissan Murano Z50?
The maximum recommended size by the factory is 255/45 R19. Installing larger tires (eg R20) is possible, but will require spacers and may result in friction against the arches when fully loaded or the suspension is running.
Can I use wheels from other Nissan models?
Wheels from models with a bolt pattern of 5x114.3 (for example, X-Trail, Teana) will theoretically fit the mounts, but you need to check the offset (ET) and the diameter of the central hole (66.1 mm). Otherwise, problems with beating and hitting the suspension elements are possible.
How often should wheels be balanced?
It is recommended to carry out balancing every 10,000 km or when changing seasonal tires. Balancing is also required after a wheel has been repaired or if you feel vibration in the steering wheel at speeds above 80 km/h.
Does wheel size affect fuel consumption?
Yes, installing heavier, larger, low-profile wheels can increase fuel consumption by 3-7% due to increased unsprung weight and aerodynamic drag. Lightweight wheels with smaller diameters contribute to savings.
