Nissan Almera Classic (also known as Nissan Almera N16 or Samsung SM3 in some countries) is a popular sedan that is still used on the secondary market. One of the key technical characteristics when selecting wheel rims or repairing hubs is central hole (or DIA - Diameter of Inner Hole). Selecting this setting incorrectly can result in steering wheel wobble, vibration at speed, or even bearing damage.

In this article we will look at what center hole diameter at Almera Classic depending on the year of manufacture and modification, how to measure it correctly, which discs fit without adapter rings, and what to do if the hole is broken or deformed. We will also consider common mistakes when replacing hubs and selecting wheels, which can cost you money and safety.

Nissan Almera Classic center hole size: official data

According to technical documentation Nissan, for Almera Classic (body N16, model years 2006–2018) the standard size of the hub center hole is:

  • 🔧 66.1 mm - for most modifications with engines 1.5 And 1.6 (including versions for Russia and the CIS).
  • 🔄 54.1 mm - found in early batches (2006–2008) for some markets, but extremely rarely.

Important: even if your car belongs to a later batch, always check the size physically, since hubs from other models could be used on the conveyor Nissan (For example, Note or Tiida).

For comparison, Almera G15 (new generation) the central hole is narrower 60.1 mm, and Nissan Sentra — 66.1 mm, which creates confusion when selecting disks.

How to measure the center hole yourself: step-by-step instructions

If you are unsure of the size or plan to buy used rims, it is better to measure the hole yourself. For this you will need:

  • 📏 Caliper (electronic or mechanical) with an accuracy of 0.1 mm.
  • 🔦 Flashlight - to illuminate the inside of the hub.
  • 🧹 Clean rag - to remove dirt and rust.

Algorithm of actions:

  1. Remove the wheel and clean the hub from dirt (especially if the car was operated in high humidity conditions).
  2. Make sure that there are no burrs or deformations on the edges of the hole - these could distort the measurement.
  3. Insert the caliper into the hole and spread the jaws until they touch the walls. Record the result.
  4. Repeat the measurement at 3-4 points around the circumference - if the values differ by more than 0.3 mm, the hub is worn out and requires replacement.

⚠️ Attention: If during measurement you get the value 66.3–66.5 mm, this may indicate wear on the seat. In this case, even new disks with DIA=66.1 mm will not sit tightly, which will lead to runout at speeds above 80 km/h.

Selection of disks: what sizes are suitable without adapter rings

When choosing wheels for Almera Classic it is important to consider not only central hole, but also other parameters:

  • 🔄 PCD (bolt pattern): 4×114.3 - standard for all modifications.
  • 📏 Departure (ET): from 35 to 45 mm (depending on the width of the disk).
  • 🛡️ DIA: 66.1 mm - optimal, but disks with 67.1 mm when using centering rings.

The table below shows disk compatibility based on the central hole:

Disc DIA (mm) Compatibility Are rings required? Risks
66.1 Perfect No No
67.1 Acceptable Yes (ring 66.1→67.1) Runout due to poor alignment
54.1 Incompatible No The disc will not fit on the hub
73.1 Conditionally Yes (ring 66.1→73.1) High risk of imbalance

Discs with DIA=67.1 mm are often offered as “universal” for Nissan/Mitsubishi, but without quality centering rings they will lead to vibrations at speeds of 100+ km/h. When buying rings, pay attention to the material: aluminum or steel is optimal, plastic deforms quickly.

Common Center Hole Problems and Solutions

Over time, the hub seat can wear out or become deformed. Let's look at the most common problems and how to fix them:

  • 🔧 Broken hole (diameter exceeds 66.1 mm): replacement of the hub or boring with installation of a repair sleeve is required.
  • 🌀 Rust on the seating surface: clean with a wire brush and treat with a rust converter (e.g. WD-40 Specialist).
  • 🚗 Steering wheel wobble after replacing discs: check the matching of DIA and PCD, wheel balancing.
  • ⚠️ The disc does not fit on the hub: There may be burrs in the way or the wrong centering ring is being used.

If you find that the hole is enlarged to 66.5 mm or more, a temporary solution may be to install disks with DIA=67.1 mm and thick centering rings (2–3 mm). However this will not fix the problem - The hub needs to be replaced as soon as possible.

What happens if you drive with a broken center hole?

Long-term operation with increased DIA leads to:

1. Uneven wear of the hub bearing (lifetime is reduced by 2–3 times).

2. Vibrations transmitted to the steering and suspension, which accelerates the wear of struts and silent blocks.

3. The risk of the disc “falling off” from the hub during a sharp maneuver (extremely rare, but possible with severe deformation).

⚠️ Attention: When replacing the hub with Almera Classic often install parts from Nissan Note (article 40520-4M000) or Tiida (40520-BM00A). They fit the fitting dimensions, but may differ in the quality of the bearing. Original hubs Nissan are marked NTN or KOYO on the body.

Replacing the hub: when is it required and how to choose a spare part

hub on Almera Classic change in the following cases:

  • 🔧 The central hole is broken (diameter >66.3 mm).
  • 🔊 There is a hum or crunch when moving (bearing wear).
  • 🌀 Wheel play when checking “on weight”.

When choosing a new hub, pay attention to:

  1. Article: original - 40520-4M000 (right) and 40521-4M000 (left).
  2. Manufacturer: preferred NTN, KOYO, SKF. Cheap analogues (for example, Febi or TRW) may have play after 20–30 thousand km.
  3. Complete set: The box should contain the hub, bearing (if not separate), snap ring and nut.

Average cost of an original hub - 5,000–7,000 rubles (for 2026). Analogs will cost 2–3 times less, but their service life rarely exceeds 50 thousand km.

💡

When replacing a hub, always replace the retaining ring and nut - they are disposable. It is also recommended to check the condition of the brake disc: if its thickness is less than 18 mm, replace it along with the hub.

Common mistakes when working with a central hole

Even experienced car owners make mistakes that lead to additional expenses. Here are the most common:

  • 🔧 Ignoring Centering Rings when installing disks with DIA=67.1 mm. This leads to imbalance and steering wheel wobble.
  • 🛠️ Tightening hub nuts without a torque wrench. Tightening torque for Almera Classic — 100–110 Nm. The constriction deforms the bearing.
  • 🌀 Installation of used hubs without checking the play. The bearing could wear unevenly, leading to vibrations.
  • 🚗 Using drives from other models (For example, Mitsubishi Lancer) without checking compatibility PCD And ET.

One of the most dangerous mistakes is center hole boring for installing disks with large DIA. This weakens the hub and can lead to its destruction when hitting a hole. If the disk does not fit, it is better to buy another one or use high-quality centering rings.

💡

Never bore the center hole of the hub! This disrupts its structure and can lead to an emergency. It is better to select wheels with a suitable DIA or use certified adapter rings.

FAQ: Frequently asked questions about the center hole of Nissan Almera Classic

Is it possible to install discs with DIA=56.1 mm if I use thick centering rings?

No, that's impossible. Centering rings compensate for the difference in 1–2 mm (for example, from 66.1 to 67.1 mm). For DIA=56.1 mm you will need a thick ring 5 mm, which will lead to unstable disk seating and vibrations. In this case, you need to either bore the disk (not recommended) or select another one.

How can you tell if the center hole is broken?

Signs of wear:

  • Steering wheel vibration at speed 80–120 km/h, even after balancing.
  • Wheel play when rocking “in weight” (checked on a lift).
  • Uneven wear of brake pads.
  • Noise (hum) from the hub, increasing when turning.

For an accurate diagnosis, measure the diameter of the hole with a caliper.

Will hubs from Nissan Tiida fit Almera Classic?

Yes, but with reservations:

  • Hubs from Tiida (article 40520-BM00A) are suitable for seating dimensions, but may differ in the quality of the bearing.
  • Original hubs Almera Classic have a longer service life (up to 150 thousand km versus 80–100 thousand km for analogues).
  • When replacing, be sure to check the match central hole (must be 66.1 mm).

What to do if after replacing the hub there is still runout?

Causes and solutions:

  1. Incorrect tightening of nuts - use a torque wrench (torque 100–110 Nm).
  2. Disc imbalance — carry out balancing on the stand.
  3. Brake disc wear - check the thickness (minimum 18 mm) and surface evenness.
  4. New bearing defect — if the hum remains, replace the hub under warranty.

Which wheels are better to choose for Almera Classic: stamped or cast?

The choice depends on the operating conditions:

  • Stamped:

    ✅ Cheaper (from RUB 1,500/piece).

    ✅ They are less afraid of holes and curbs.

    ❌ Heavier (worse dynamics).

    ❌ Prone to corrosion.

  • Cast:

    ✅ Lighter (improves acceleration and braking).

    ✅ Accurate geometry (better for balancing).

    ❌ More expensive (from RUB 3,000/piece).

    ❌ May crack if hit hard.

For city use, alloy wheels with DIA=66.1 mm And ET=38–42 mm. For off-road use, stamping is better.
