Choosing the right tires for your crossover Nissan Murano second generation (Z51 body) is a critical aspect of operation, directly affecting safety, fuel consumption and driving comfort. This car has impressive dimensions and weight, so the requirements for tires here are much higher than for compact city models. An incorrectly selected size can lead to speedometer errors, problems with ABS operation, and even mechanical damage to the suspension when turning the steering wheel.
The manufacturer has provided several factory options for rims and tires, which gives the owner freedom of choice depending on the season and road conditions. However, there is a strict range of acceptable parameters that cannot be violated without serious intervention in the design of the car. In this article we will look in detail at all acceptable tire sizes for Nissan Murano Z51, installation nuances and operating features in different climatic zones.
Factory specifications and standard tire sizes
Original equipment Nissan Murano Z51 was offered with wheels of different diameters, which automatically dictates the choice of tire profile height. The main standards for this body are wheels with a diameter of 17, 18 and 20 inches. The smallest size is usually installed on base versions, while top trims are equipped with massive 20-inch wheels for improved appearance and handling on dry pavement.
The most common and universal size for this crossover is 235/65 R17. This option provides an excellent balance between comfort, flotation and suspension durability. A profile height of 65% allows the wheel to effectively dampen road unevenness, which is especially important for vehicles operated on less-than-ideal Russian roads. Also common size 235/60 R18, which slightly reduces the profile height, but improves directional stability.
For those who prefer a sportier look and dynamics, the manufacturer has provided the installation of wheels with a diameter of 20 inches. In this case, the size rubber used is 255/50 R20. It is important to understand that when moving to this size, not only the appearance of the car changes, but also its behavior on the road. Reducing the sidewall makes steering sharper, but can lead to increased suspension stiffness and the risk of damage to the disc if you hit a deep hole.
Regardless of the selected diameter, the tire width for Nissan Murano Z51 usually varies between 235-255 mm. This is a critically important parameter, since tires that are too narrow will not provide the necessary contact patch area for such a heavy car, and tires that are too wide can touch the arches when fully loaded or in the cold, when the rubber becomes harder. The factory width tolerance is +/- 10 mm from the standard value without the need to change the suspension geometry.
- π‘ Main standard size: 235/65 R17 for maximum cross-country ability.
- π Sports version: 255/50 R20 for better handling.
- βοΈ Universal compromise: 235/60 R18 for a balanced ride.
Table of permissible disk sizes and parameters
To avoid confusion when selecting tires, you must rely on clear technical data. Below is a summary table that contains all the official tire sizes recommended for the Z51 body, as well as wheel parameters (offset, number of bolts, center hole diameter). This data is comprehensive for finding a replacement or set of seasonal tires.
| Disc diameter | Tire size | Departure (ET) | Bolt pattern | Center Diameter (DIA) |
|---|---|---|---|---|
| 17 inches | 235/65 R17 | ET 45 | 5x114.3 | 66.1 mm |
| 18 inches | 235/60 R18 | ET 45 | 5x114.3 | 66.1 mm |
| 18 inches | 255/55 R18 | ET 45 | 5x114.3 | 66.1 mm |
| 20 inches | 255/50 R20 | ET 45 | 5x114.3 | 66.1 mm |
Please note that the parameter bolt pattern 5x114.3 is common to most models Nissan and Infiniti period, making it easier to find analog discs. However, the diameter of the central hole 66.1 mm must be strictly followed, or the use of adapter rings is necessary to avoid vibration on the steering wheel when driving.
β οΈ Attention! Installing wheels with an offset (ET) other than standard (for example, ET 35 or ET 55) can lead to accelerated wear of the wheel bearings and changes in the vehicle's trajectory when cornering.
When choosing non-original discs, be sure to check the markings. If you plan to use third-party alloy wheels, make sure they are certified for heavy-duty SUVs. Car wheels may not support the weight Murano and deform at the first serious load.
- 17 inches (235/65)
- 18 inches (235/60)
- 20 inches (255/50)

Specifics of choosing summer and winter tires
Choosing between summer and winter tires for Nissan Murano Z51 requires taking into account not only climatic conditions, but also the features of the All-Mode 4x4-i all-wheel drive. In summer, the priority is sidewall rigidity and a tread pattern that provides a high level of grip on wet asphalt. Tires with a directional tread pattern that effectively drain water are ideal for this crossover.
Winter operation dictates its own rules. For northern regions, the use of studded tires is strongly recommended, since the standard all-wheel drive system will not be able to operate effectively on ice without the appropriate tires. If you move mainly on cleared city roads, you can consider the option of friction rubber (βVelcroβ). The main requirement for a winter tire is to maintain elasticity at temperatures below -10Β°C.
When replacing tires with winter ones, there is often a temptation to install tires of a smaller diameter (for example, R17 instead of R20) to save money. This is a valid solution, but it must be accompanied by the correct selection of the profile. The overall height of the wheel must remain unchanged so as not to confuse the speedometer readings or interfere with the operation of the safety systems. For example, when moving from 255/50 R20 on R17, you need to look for the size 235/65 R17, since their outer diameter is almost identical.
- π§οΈ Summer tires: choose models with a high speed index (V or W) for safety on the highway.
- βοΈ Winter tires: give preference to studded models for a confident start on ice.
- π Versatility: All-season tires are not recommended for harsh winters as they do not provide adequate grip.
Tire pressure and its effect on performance
Correct tire pressure for Nissan Murano Z51 - this is not just a recommendation, but a technical necessity that affects tread wear and fuel consumption. Recommended pressure values ββdepend on the load on the vehicle and the size of the installed wheels. This information is usually located on a sticker located on the driver's door pillar or on the inside of the gas cap.
For standard sizes R17 and R18 with normal load (2-3 passengers), the optimal pressure is 2.3 bar (33 PSI) in front and rear wheels. When the car is fully loaded (five passengers + luggage), the pressure should be increased to 2.5-2.6 bar (36-38 PSI). Ignoring these recommendations may result in uneven tread wear around the edges or in the center of the tire.
If you have installed non-standard large diameter wheels (such as R20), the pressure requirements may change slightly. In such cases, it is better to focus on the maximum pressure indicated on the sidewall of the tire, but do not exceed it. Too high pressure will make the suspension Murano hard and jerky, and too low will increase the risk of sidewall βherniaβ on uneven surfaces.

Installation nuances and possible problems
The process of installing new tires on Nissan Murano Z51 may have its pitfalls, especially if you change disk sizes. One of the common problems when installing R20 wheels is that they hit the suspension elements or protective shields when the steering wheel is turned to maximum. This is because the 255mm tire width requires more space than the stock 235mm.
When installing a winter kit on wheels of a smaller diameter (for example, R17 instead of R20), you must ensure that there is sufficient clearance between the tire and the arch. Sometimes, especially if there are protective fender liners, it becomes necessary to remove or adjust them. It is also important to check that the spare wheel (replacement wheel) fits in its normal place under the trunk floor if it differs in size from the main wheels.
An important aspect is balancing. Murano - a heavy car, and an imbalance of even 50-100 grams on a wheel can cause noticeable vibration on the steering wheel and body at speeds above 80 km/h. Use only high-quality balancing weights and require the tire shop to perform accurate balancing with a tolerance of no more than 5 grams.
What to do if an arch hits you?
If, when turning the steering wheel all the way, the tire touches the fender liner, try removing the plastic fender liner or lifting it slightly. In rare cases, it may be necessary to install spacers, but this may impair handling.
Don't forget about the pressure control system. When changing wheels, rotate the TPMS sensors carefully. Damage to the sensor when mounting the tire on the rim will result in the system not working and you will not receive a puncture warning. In some cases, when using old disks, the sensors may not work correctly due to oxidation of the contacts.
- π§ Installation: Use a mounting paddle with a soft tip to avoid damaging the sensitive tire bead.
- βοΈ Balancing: require βadjustmentβ of weights if there is vibration on the steering wheel.
- π‘οΈ Protection: check the gaps between the tire and the arch when fully loaded and the steering wheel turned out.
Proper balancing and compliance with the recommended pressure is the key to suspension durability and road safety for the Murano Z51 heavy crossover.
FAQ: Frequently asked questions from Nissan Murano Z51 owners
Crossover owners often face issues related to tire selection and operation. Below we have collected answers to the most common questions that will help you avoid mistakes when servicing your car.
Is it possible to install R18 tires on a Murano instead of the standard R20?
Yes, you can. The size 235/60 R18 is factory-fitted and fully compatible with the suspension. The main thing is that the overall diameter of the wheel remains close to the standard one, so that the speedometer readings do not go astray and errors do not occur in the operation of the ABS and ESP systems.
What load index is required for the Murano Z51?
For this car, the minimum permissible load index is 104 (900 kg per wheel) for summer tires and 105 (925 kg) for winter tires. The use of tires with a lower load index is strictly not recommended, as they may not support the weight of the vehicle when fully loaded.
How often should you change tires on a Nissan Murano?
The recommended tire service life is 5-6 years or a mileage of 60,000 - 80,000 km, depending on operating conditions. If the tread depth has decreased to 4 mm for winter tires or 1.6 mm for summer tires, the tire must be replaced immediately.
Do I need to replace TPMS sensors when purchasing new wheels?
If you are purchasing new wheels, it is best to install new TPMS sensors right away. Old sensors may be worn out, have a dead battery, or have a damaged housing. This will save you time and money in the future.
Does tire width affect fuel consumption?
Yes, installing wider tires (for example, moving from 235 to 255 mm) increases rolling resistance, which can lead to an increase in fuel consumption by 0.5-1.0 liters per 100 km. However, this is compensated by improved directional stability.
