Choosing the right tires for a crossover Nissan Murano the second generation (Z51 body) is not just a matter of aesthetics, but a critical aspect of safety and comfort. This car, characterized by a smooth ride and a powerful engine, requires a special approach to choosing a tire set, since the wrong size can significantly affect the operation of the electronic stabilization systems and anti-lock brakes.
Owners are often faced with the dilemma of whether to stick with stock sizes or upgrade to wider, lower-profile wheels for an improved appearance. However, the factory settings for the suspension and steering Nissan Murano Z51 are designed for specific parameters, deviation from which can lead to increased wear of suspension elements and reduced fuel efficiency.
Standard tire sizes for Z51 body
Manufacturer Nissan provided several factory configuration options for the model Murano Z51, which depend on the year of manufacture and level of equipment. The main dimensions found in specifications are 235/65 R17 and 235/60 R18. These dimensions provide an optimal balance between comfort, off-road performance and dynamic performance of the vehicle.
For those who prefer a sportier look and better handling at high speeds, 20-inch wheels are often used. In this case, the standard tire size changes to 235/55 R20. It is important to understand that as the rim diameter increases, the tire profile height decreases, which makes the suspension more rigid and sensitive to uneven road surfaces.
In addition, there are specific sizes for winter tires, which may differ from summer sets. Some owners install 235/70 R16 or 235/60 R17 to improve cross-country ability in winter by increasing the profile height. However, before such a replacement, it is necessary to ensure that the increased outer diameter of the wheel will not interfere with the arches when the suspension is fully compressed.
- ✅ 235/65 R17 - ideal for harsh winter conditions and bad roads
- ✅ 235/60 R18 - the golden mean for mixed use
- ✅ 235/55 R20 - the choice for the highway and urban environments with ideal asphalt
Disc parameters and offset
When selecting tires, we must not forget about the parameters of the wheels themselves, since they directly affect the fit of the tire and operational safety. For Nissan Murano Z51 the diameter, rim width, number of holes and offset (ET) are critical. Incorrect offset can cause the wheel to touch suspension components or protrude beyond the fender.
Factory disk parameters for this model are usually 5x114.3 for bolt pattern and offset ranging from 40 до 45 мм. Rim width most often varies from 7.5 to 8.5 inches depending on the diameter of the wheel. Using discs with an offset of less than 40 mm can cause misalignment of the wheel bearings and accelerated wear of the suspension arms.
If you plan to install aftermarket discs, be sure to check their compatibility with the brake calipers. Large brake mechanisms installed on top versions Murano, may not fit inside rims with a small inner diameter or incorrect spoke profile.
| Disc diameter | Rim Width (J) | Departure (ET) | Bolt pattern | Central hole |
|---|---|---|---|---|
| 17 inches | 7.5J | 45 | 5x114.3 | 66.1 mm |
| 18 inches | 8.0J | 42 | 5x114.3 | 66.1 mm |
| 20 inches | 8.5J | 40 | 5x114.3 | 66.1 mm |
⚠️ Attention! Installing discs with an offset different from the factory one (less than 35 mm or more than 50 mm) is strictly not recommended without consulting engineers, as this disrupts the steering geometry and can lead to loss of control over the car.

Tire pressure: adjustment nuances
Tire pressure is a parameter that is often ignored, although it directly affects tire wear, fuel consumption and handling. For Nissan Murano Z51 The recommended pressure depends on the vehicle load and the size of the wheels installed. Typically, this data is indicated on a sticker located on the driver's door pillar or in the gas tank flap.
In standard operating mode (1-2 passengers, small luggage), the optimal pressure is considered to be in the range 2.2 - 2.3 bar for all wheels. If the vehicle is loaded to capacity or is used to tow a trailer, the pressure must be increased to 2.6 - 2.8 barto avoid tire overheating and sidewall deformation.
Monitor the pressure difference between the axles. The permissible difference should not exceed 0.2 bar. If the deviation is significant, the tire pressure monitoring system (if installed) may generate an error and the vehicle will begin to pull to the side when driving in a straight line.
- 🌡️ In summer, check the pressure on cold tires in the morning before driving
- 🌡️ In winter, pressure can drop by 0.1-0.2 bar in severe frost
- 🌡️ After a long trip, the pressure rises - do not release it hot

Seasonal features and tire choice
Climatic operating conditions dictate their own rules for choosing tires. For areas with mild winters and short summers, all-season tires are fine, but for severe winter conditions, two sets of tires are highly recommended. Summer tires on Murano Z51 Sidewalls should have high rigidity for cornering stability, and winter ones should have a soft composition that retains elasticity at low temperatures.
When choosing winter tires, pay attention to the presence or absence of studs. Studded tires provide better grip on ice, but significantly increase noise and wear on asphalt. For cities with clean roads, it is better to choose Velcro-type friction rubber, which is quieter and softer.
It is important to consider that Nissan Murano has a high center of gravity, so the rubber must provide maximum contact patch with the road. Do not skimp on the tire brand, as cheap analogues often have an unstable rubber compound, which leads to rapid wear and deterioration of the braking distance.
⚠️ Attention! It is prohibited to install winter studded tires on the front axle and summer tires on the rear axle (or vice versa). This can lead to loss of control and the vehicle skidding when braking.
What is a tire wear indicator?
Each tire has a wear indicator - a protrusion 1.6 mm high. If the tread has worn down to this level, the tire must be replaced, as its grip on wet roads is sharply reduced.
Effect of size on speedometer and odometer
Any change in tire size from the factory standard will inevitably affect the speedometer and odometer readings. If you install wheels with a large outer diameter, the speedometer will show a lower speed than the actual speed, and the odometer will show less mileage than the actual mileage. Conversely, a smaller diameter will lead to an overestimation of readings.
For Nissan Murano Z51 An error within 2-3% is considered acceptable and does not require adjustment of software settings. However, when installing non-standard sizes (for example, switching from R17 to R20 with a change in profile height), the error can reach 5% or more, which creates the danger of speeding without your knowledge.
If you are planning a significant change in wheel size, it is recommended to use a tire calculator to calculate the error. It is also worth considering that the pressure monitoring system (TPMS) and directional stability systems may not work correctly if there is a large discrepancy between the calculated and actual wheel diameters.
Before installing a new set of wheels, write down your current mileage and speedometer readings so you can easily check the measurement error on the new tires.
Replacement and balancing rules
The process of replacing tires Murano Z51 requires care and adherence to technology. Due to the heavy weight of the vehicle and the complex design of the suspension, the wheel nuts must be tightened with a certain force. Use a torque wrench to avoid over- or under-tightening the bolts.
Wheel balancing is a mandatory procedure after replacing tires or installing new wheels. For crossovers with large rim diameters (20 inches), the balance requirements are more stringent, since even a small imbalance at high speed causes strong vibrations that are transmitted to the steering wheel and body.
When replacing seasonally, be sure to mark the wheels (front left, rear right, etc.) so that they can be installed in the same places the next time you replace them. This will help maintain even tread wear and extend the life of the tire set.
- 🔧 Wheel bolt tightening torque:
100-110 Nm - 🔧 Use only original or certified spacers if necessary
- 🔧 Check the condition of the CV joint boots after removing the wheels
⚠️ Attention! Never use a pneumatic impact wrench to final tighten bolts. This can lead to disc deformation, damaged threads and the wheel coming loose while moving.
Regular balancing and proper tightening of bolts is the key to safety and vibration-free steering wheel of the Nissan Murano Z51.
Common mistakes when choosing tires
Many owners make typical mistakes when choosing tires, focusing only on appearance or price. One of the most common mistakes is trying to install wheels with a smaller diameter than those provided by the factory, hoping for a lower cost of tires. This often leads to the tire hitting the suspension elements or arches when driving.
Another mistake is ignoring the speed and load index. Nissan Murano is a heavy and fast vehicle, so using tires with a low load index (for example, L instead of H) may cause the tire to blow out under high load or speed.
You should also avoid mixing tires of different manufacturers and models on the same axle. Varying tread hardness and pattern can cause unstable vehicle behavior during cornering and during emergency braking, which is especially dangerous for a crossover with a high center of gravity.
How to check the load index?
The load index is indicated on the sidewall of the tire as a two- or three-digit number (for example, 103). Each number corresponds to the maximum load in kilograms. For Murano Z51, the minimum load index is usually 103-105.
Where and when to change tires
The optimal time to replace tires is during the transition periods: spring and autumn. Don't wait for the first snow or extreme heat, as this may cause queues at tire shops. Plan replacement in advance when the air temperature is consistently above or below +7 degrees Celsius.
Choose services that have experience working with premium cars and large rim diameters. Mistakes when installing rubber on a 20-inch wheel can lead to damage to an expensive rim or tire sidewall. Make sure that the equipment in the service meets modern standards.
After replacement, be sure to test drive at low speed to ensure there is no wheel play and proper installation. If you feel vibration in the steering wheel or body, return to the service center to have it rebalanced.
What is the most popular tire size for the Nissan Murano Z51?
The most popular size is 235/65 R17, as it provides better comfort and flotation compared to larger wheels, while remaining quite reliable and inexpensive to maintain.
Is it possible to install tires with a lower speed index?
Strongly not recommended. The speed index must match or exceed the vehicle's maximum speed. Using tires with a low index can lead to their destruction at high speed.
How often do you need to change tires on your Murano Z51?
The average service life of high-quality rubber is 4-5 years or 60-80 thousand kilometers. However, if deep cracks, hernias or wear of the tread up to 1.6 mm appears, replacement must be made immediately.
Does tire size affect fuel consumption?
Yes, installing wider and larger tires (for example, 20 inches instead of 17) increases rolling resistance and wheel weight, which can lead to an increase in fuel consumption by 5-10%.
