Nissan Patrol on 42 wheels: why did this SUV conquer off-road?

When it comes to true SUVs that can overcome any obstacle, Nissan Patrol always ends up at the top of the list. What if you add a magic number to his name? 42, then what appears before us is not just a car, but a real off-road legend. But what is hidden behind this number? Why exactly 42 wheels became a symbol of invincibility Patrol?

In fact, we are not talking about the physical number of wheels (although some extreme modifications come close to this number), but about tire width in inches. 42" wheels is the ultimate dream for most off-road enthusiasts, turning Patrol into an invincible monster capable of conquering sands, swamps and mountain trails. In this article we will look at what makes this modification so special, what technical nuances need to be taken into account, and whether it is even worth installing such wheels on your car.

What are 42-inch wheels and why does Patrol need them?

First, let's understand the terminology. When they talk about 42 wheels, they mean tires with bore diameter, which when added to the profile height gives an overall diameter of about 42 inches (106.68 cm). For comparison: standard wheels on Nissan Patrol Y62 (latest generation) are about 32-33 inches in diameter. A difference of 9-10 inches dramatically changes the characteristics of the car.

The main reasons why Patrol owners switch to these wheels:

• 🏜️ Increased ground clearance — due to the larger diameter of the wheels, the car rises higher above the ground, which allows it to overcome deeper holes and obstacles.
• 🌊 Better cross-country ability on sand and mud - wide contact area reduces ground pressure, reducing the risk of getting stuck.
• 💪 Improved suspension geometry — large wheels increase approach/departure angles, which is critical for serious off-road conditions.
• 🚙 Aesthetics and status — Patrol on 42 wheels looks aggressive and impressive, emphasizing the seriousness of the owner.

However, not everything is so simple. Installing such wheels requires serious modifications to the car. Without preparation, you risk encountering problems: from wheel friction on the wheel arch liners to transmission failure. Therefore, before rushing into tuning, you need to understand is your Patrol ready for such changes?.

Technical requirements for installing 42-inch wheels

If you decide to take this step, the first thing you need to do is assess what changes your car will need. Here are the main aspects to consider:

1. Suspension and ground clearance. The standard Patrol suspension is not designed for such loads. You will need:

• 🔧 Installation elevator kits (suspension lift 4-6 inches).
• 🔧 Replacing shock absorbers with reinforced ones (for example, FOX or King Shocks).
• 🔧 Modification or replacement of springs to maintain correct geometry.

2. Transmission and transfer case. Large wheels increase the load on all components:

• ⚙️ Replacement of main pairs in bridges (for example, with 4.88 or 5.13) to compensate for changes in gear ratios.
• ⚙️ Installation of enhanced differential (For example, ARB Air Locker).
• ⚙️ Modification of the transfer case to work with increased wheel weight.

3. Body and arches. To prevent the wheels from rubbing against the body, you will need:

• 🔨 Widening wheel arches (or installing fenders).
• 🔨 Possible trimming of bumpers to increase departure/entry angles.

4. Brake system. Increased wheel weight requires more effective braking:

• 🛑 Installation of larger diameter brake discs.
• 🛑 Replacing brake calipers with more powerful ones.

Don't forget about steering. Large wheels increase the load on the steering rack, so it may need to be replaced or installed hydraulic booster with increased productivity.

The best 42-inch wheel models for Nissan Patrol

Choosing tires is one of the most important stages. Not all 42-inch wheels are created equal for the Patrol. Here are the most popular and proven models:

Model	Manufacturer	Tread type	Features	Approximate price (per piece)
Baja Boss M/T	Milestar	Mud-Terrain	Aggressive tread, self-cleaning, high sidewalls	~120,000 rub.
Trazz A/T	Nitto	All-Terrain	Good balance between highway and off-road, low noise levels	~135,000 rub.
Red Label M/T	Toyo	Mud-Terrain	Reinforced sidewalls, excellent cross-country ability on mud and stones	~150,000 rub.
Krawler KX	Interco	Extreme offroad	Maximum grip on rocks, but noisy on asphalt	~180,000 rub.

When choosing tires, pay attention not only to the brand, but also to load index And speed index. For Patrol with 42-inch wheels, the minimum load index should be 126/123 (1700 kg per wheel), and the speed index is not lower Q (160 km/h), even if you don't plan to drive that fast.

It is also worth considering that mud tires (M/T) will make noise on the asphalt and wear out faster, while all-terrain (A/T) more versatile, but less effective on serious off-road conditions. The choice depends on your priorities.

Pros and cons of Patrol on 42 wheels

Like any major modification, installing 42-inch wheels has its pros and cons. Let's break them down in detail so you can make an informed decision.

Benefits:

• ✅ Absolute cross-country ability — Patrol on such wheels is able to overcome almost any off-road conditions, including deep sand, swamps and rocky areas.
• ✅ Unique appearance — the car takes on an aggressive and powerful appearance, which immediately makes it stand out on the road.
• ✅ Increased ground clearance — even without a lift kit, large wheels raise the body higher, improving geometric cross-country ability.
• ✅ Better shock absorption — the high profile of the tires softens impacts on uneven surfaces, increasing comfort on off-road terrain.

Disadvantages:

• ❌ Decreased dynamics — a large mass of wheels impairs acceleration and braking, especially on asphalt.
• ❌ Increased fuel consumption — due to increased rolling resistance and weight, consumption may increase by 20-30%.
• ❌ Rapid transmission wear — without modification of the main pairs and the transfer case, the service life of the units is reduced.
• ❌ Difficult to manage - at high speeds the car becomes less stable and the steering wheel becomes heavier.
• ❌ High cost — sets of wheels + modifications will cost from 1 to 2 million rubles.

It is important to understand that Patrol on 42 wheels is not a universal car. It's ideal for off-road use, but can be a bit of a nuisance on everyday commutes around town. If you plan to use the car primarily on asphalt, these wheels are not the best choice.

What happens if you don't modify the transmission?

Without replacing the main pairs in the axles, the engine will operate at higher speeds, which will lead to overheating, increased fuel consumption and a reduction in gearbox life. In severe conditions (such as towing or driving in deep mud), this can cause damage to the differential or transfer case.

Real experience of owners: reviews and advice

To better understand whether it's worth upgrading to 42-inch wheels, let's look at the experiences of real owners Nissan Patrolwho have already walked this path.

Andrey, Moscow (Patrol Y62, 2018):

⚠️ Attention: "I put Baja Boss M/T 42x14.50R20 for lifted suspension (+5 inches). Passability has become simply space - the sands of Dubai are now like asphalt. But on the highway above 120 km/h the car begins to “steer” a little, and consumption increased from 16 to 22 liters. If I had known in advance, I would have made a 6-inch lift and changed the main pairs right away."

Igor, Yekaterinburg (Patrol Y61, 2010):

⚠️ Attention: "I put it on Y61 Interco Krawler 42x15.50R17. It couldn't be done without an elevator - we had to cut the arches and install fenders. The main thing is not to skimp on balancing, otherwise strong vibration will begin at speeds above 100 km/h. I also advise you to immediately replace the steering rods with reinforced ones."

Dmitry, Krasnodar (Patrol Y62, 2020):

⚠️ Attention: "I chose Nitto Trazz A/T — they are less aggressive, but they are not so noisy on the asphalt. The ground clearance has increased by 8 cm, which is a lifesaver for our roads. However, we had to change the brake discs to larger ones, as the standard ones overheated. Advice: if you drive a lot around town, take the A/T rather than the M/T."

There are several key takeaways from these reviews:

• 🔹 Suspension lift is required — without it, the wheels will rub against the body.
• 🔹 Balancing is critical - Improperly balanced wheels will lead to vibrations.
• 🔹 Brakes and steering need attention — they need to be strengthened or modified.
• 🔹 The choice of tread depends on your riding style — M/T for off-road, A/T for versatility.

Step-by-step instructions for installing 42-inch wheels

If you decide to take this step, here is a step-by-step action plan. Remember: it is better to entrust this work to professionals, but understanding the process is useful for every owner.

Step 1. Preparing the car

• 🔧 Conduct a complete diagnosis of the suspension, transmission and brake system.
• 🔧 Replace all worn parts (silent blocks, balls, shock absorbers).
• 🔧 Remove standard wheels and prepare a work area.

Step 2. Installation of the lift kit

• 🔧 Raise the car on a lift and remove the standard springs/shock absorbers.
• 🔧 Install new springs and shock absorbers from a lift kit (for example, Old Man Emu or Ironman 4x4).
• 🔧 Adjust the suspension geometry according to the manufacturer's instructions.

Step 3. Transmission Modification

• ⚙️ Remove the rear and front axles.
• ⚙️ Replace the main pairs with options with a gear ratio of 4.88 or 5.13.
• ⚙️ Install differential locks (optional, but recommended).

Step 4. Install the wheels

• 🚗 Put new wheels and tires on the hubs.
• 🚗 Carry out balancing (preferably dynamic).
• 🚗 Check the absence of friction when the steering wheel is fully turned and the suspension travels.

Step 5. Setup and test drive

• 🔧 Carry out a wheel alignment.
• 🔧 Check the operation of the brake system and steering.
• 🔧 Take a test drive on off-road and asphalt to identify possible problems.

Important: after installing the wheels first 500 km Avoid sudden acceleration and braking, as well as high speeds. This will allow the new parts to “get in” and avoid premature wear.

Alternatives to 42-inch wheels: when should you choose a different size?

As attractive as 42-inch wheels are, they are not for everyone. In some cases, it makes more sense to choose a different size. Let's look at when this is justified.

35" wheels - ideal option if:

• 🔹 You drive off-road, but not extreme (forest roads, light off-road).
• 🔹 Do you want to maintain controllability and comfort on the asphalt.
• 🔹 Not ready to spend a lot of money on modifying the transmission.

Advantages: minimal modifications (a 2-3-inch lift is enough), lower fuel consumption, wider selection of tires.

37" wheels - gold standard for:

• 🔹 Serious off-road (sand, mud, shallow fords).
• 🔹 Owners who want a balance between cross-country ability and everyday use.

Advantages: noticeable improvement in cross-country ability at moderate modification costs.

40" wheels - choice for:

• 🔹 Extreme off-road (rocks, deep sand, swamps).
• 🔹 Owners who are willing to sacrifice comfort for maximum cross-country ability.

Advantages: almost the same cross-country ability as the 42-inch, but with less modification costs.

If you are still in doubt about which size to choose, answer these questions:

• 🤔 How often do I drive on serious off-road?
• 🤔 Am I ready to sacrifice comfort on the asphalt?
• 🤔 How much am I willing to spend on modification?

An honest answer to these questions will help you determine the optimal wheel size for your Patrol.

FAQ: Frequently asked questions about Patrol on 42 wheels

❓ Do I need to register changes with the traffic police after installing 42-inch wheels?

Yes, definitely. Changing the wheel size is considered a change to the design of the vehicle. You will need to go through technical expertise and obtain permission for refurbishment. Without this, you will not be able to pass the technical inspection, and in the event of an accident, problems may arise with the insurance company.

❓ Which engine is better suited for Patrol with 42 wheels: gasoline or diesel?

Optimal choice - diesel engine, for example, YD25DDTi (3.0 l) or V9X (in new models). Diesels have more torque at low speeds, which is critical for heavy wheels. Gasoline engines (for example, VK56VD) are more powerful, but less economical and cope worse with off-road loads.

❓ Is it possible to install 42-inch wheels on Patrol Y61 (old generation)?

Technically yes, but it would require even more improvementsthan for Y62. The Y61 has a weaker frame and suspension, so you will have to strengthen the side members, change the axles to stronger ones (for example, from Nissan Titan) and install portal gearboxes. The budget for such modifications may exceed 3 million rubles.

❓ What is the service life of 42-inch wheels?

The service life depends on the type of tread and operating conditions:

• 🔹 M/T (mud): 30-40 thousand km with active off-road conditions.
• 🔹 A/T (all-terrain): 50-60 thousand km with mixed driving.

To extend the life of your tires, check them regularly. pressure (optimally 1.8-2.2 bar for M/T) and spend rotation every 10 thousand km.

❓ Where is the best place to buy wheels and components for Patrol?

Reliable options:

• 🛒 Official dealers Nissan (for original spare parts).
• 🛒 Specialized off-road stores (for example, 4x4Shop, OffRoadMaster).
• 🛒 Foreign online stores (for example, 4WheelParts, ExtremeTerrain) - but be prepared for long delivery times and possible customs problems.

Beware of fakes! Buy tires only from trusted sellers with a guarantee.
