Nissan Cefiro A33: wheel bolt pattern, PCD, ET offset and center hole diameter

Nissan Cefiro A33 (1994–2003) is a legendary Japanese sedan that is still in demand due to its reliability, comfort and tuning potential. However, when replacing wheels or disks, owners often face the question: What kind of bolt pattern does Cefiro have? An error in choosing parameters can lead to vibrations, premature wear of wheel bearings or even emergency situations.

In this article we will analyze in detail all the technical nuances: from standard PCD 5×114.3 to permissible overhang values (ET) and the diameter of the central hole (CO). You will also find compatibility tables, tips for selecting non-standard drives, and answers to frequently asked questions. The information is relevant for all modifications A33, including versions with engines VQ20DE, VQ25DE And VQ30DE.

What is a bolt pattern and why is it important for the Nissan Cefiro A33

Bolt pattern (or PCD - Pitch Circle Diameter) is the diameter of the circle on which the centers of the wheel rim mounting holes are located. For Nissan Cefiro A33 this parameter is fixed and is 5×114.3 mm (5 holes located on a circle with a diameter of 114.3 mm). Deviation from this value will make it impossible to install the disk correctly.

But PCD is not the only critical parameter. Important things to consider:

• 🔧 Disc offset (ET) — the distance from the mating plane of the disk to its central axis. For A33 standard offset varies from ET35 to ET45.
• 🕳️ Central hole diameter (CO) - must be no less 66.1 mm, otherwise the disc will not fit on the hub.
• 🔩 Bolt diameter and length - standard bolts for Tsefiro have a thread M12×1.25 and length 27–30 mm.

Ignoring these parameters is fraught with:

• ⚠️ Steering wheel vibration at speeds above 80 km/h (due to imbalance).
• ⚠️ Accelerated wear suspension and wheel bearings.
• ⚠️ Difficulty balancing wheels (if the CO does not match).

⚠️ Attention: On some modifications Cefiro A33 (for example, with all-wheel drive 4WD) bolts with different thread lengths can be used. Before purchasing disks, check this parameter in the technical documentation or on the bolt itself (the markings are stamped on the head).

Standard bolt pattern parameters for Nissan Cefiro A33

The table below shows the factory wheel parameters for all modifications Nissan Cefiro A33 (1994–2003). This data is relevant for sedans with engines VQ20DE, VQ25DE, VQ30DE, as well as for versions with automatic and manual transmission.

Parameter	Meaning	Note
Bolt Pattern (PCD)	5×114.3	5 holes, circle diameter 114.3 mm
Departure (ET)	ET35–ET45	±2mm deviation allowed for non-standard discs
Central hole (CO)	66.1 mm	You can use discs with a large center of gravity, but with adapter rings
Bolt thread	M12×1.25	Thread length: 27–30 mm (depending on drive type)
Wheel diameter (standard)	R15–R16	On tuned versions they install up to R18

It is important to understand that even if there is a coincidence PCD And CO wrong departure (ET) may lead to:

• 🔧 Disc contact o suspension or caliper elements.
• 🔧 Steering axis displacement, which impairs controllability.
• 🔧 Incorrect ABS operation (if the wheel sensors are displaced relative to the standard position).

Compatible with other Nissan and Infiniti models

Thanks to a unified platform Nissan Cefiro A33 shares the bolt pattern parameters with a number of other models of the concern. This simplifies the search for spare parts and allows you to use discs from:

• 🚗 Nissan Maxima A32/A33 (1994–2004) - full compatibility for PCD and central heating.
• 🚗 Nissan Laurel C34 (1993–1999) - identical parameters, but the offset may differ.
• 🚗 Infiniti I30 (1995–2001) - the same PCD 5×114.3, but check the CO (sometimes 67.1 mm).
• 🚗 Nissan Skyline R33/R34 (sedans) - the bolt pattern is the same, but the offset may be different (ET30–ET40).

However, there are nuances:

• ⚠️ Discs from Nissan Primera P11 (even with PCD 5×114.3) may not be suitable due to other CO (59.1 mm).
• ⚠️ On Infiniti Q45 (1990–1996) bolt pattern 5×114.3, but crashes often ET25–ET35, which is incompatible with Cefiro.

⚠️ Attention: When installing discs from Skyline R33/R34 on Cefiro A33 It may be necessary to replace the hub bolts with longer ones (up to 35 mm), since the original bolts Tsefiro in short.

If you plan to use drives from another model, be sure to check the compatibility table:

Model	PCD	CO (mm)	Departure (ET)	Compatibility
Nissan Maxima A33	5×114.3	66.1	35–45	✅ Full
Infiniti I30	5×114.3	66.1–67.1	35–45	✅ With adapter ring
Nissan Skyline R33 (sedan)	5×114.3	66.1	30–40	⚠️ Touch check required
Nissan Laurel C34	5×114.3	66.1	35–45	✅ Full

How to measure bolt pattern yourself

If you are not sure about the parameters of your Cefiro A33 (for example, after tuning or replacing hubs), you can measure the bolt pattern yourself. You will need:

• 📏 Caliper or ruler with high accuracy.
• 🔨 Square (for measuring the distance between the centers of the holes).

PCD measurement algorithm:

1. Remove the wheel and clean the hub from dirt.
2. Measure the distance between the centers of two adjacent holes (for example, L = 72 mm).
3. For a 5-bolt bolt pattern, use the formula:

   PCD = L / sin(180° / 5) ≈ L / 0.5878

   Let's substitute L = 72 mm:

   PCD ≈ 72 / 0.5878 ≈ 122.5 мм

   But this is not true! The correct measurement is between non-neighboring holes (through one). Then:

   PCD = L / sin(360° / 5) ≈ L / 0.9511

   For Cefiro A33 the distance between non-adjacent holes should be ~108.6 mm, which when substituted gives PCD ≈ 114.3 mm.

To check central hole (CO):

• Measure the diameter of the hole in the hub (should be 66.1 mm).
• If the disc hole is larger, use centering rings (For example, 67.1→66.1 mm).

Selection of non-standard disks: what you need to know

Many owners Nissan Cefiro A33 tend to install larger diameter discs (for example, R17 or R18) to improve appearance. However, there are limitations:

• 🔧 Max diameter without suspension modifications - R18 with low profile tires (for example, 225/40 R18).
• 🔧 Minimum reach for R17–R18 — ET30 (with ET25 and below, touching is possible).
• 🔧 Disc width should not exceed 8.5J (otherwise you will need to roll out the arches).

Example of compatible configurations:

Disc diameter	Disc width	Departure (ET)	Recommended tires
R15	6.5J	ET40	205/65 R15
R16	7J	ET38	215/55 R16
R17	7.5J	ET35	215/45 R17
R18	8J	ET30	225/40 R18

When choosing non-standard disks, consider:

• ⚠️ Disc weight — heavy cast or forged wheels increase the load on the suspension.
• ⚠️ Knitting needle shape - some models may block access to calipers or ABS sensors.
• ⚠️ Balancing — wide wheels (8J+) require more precise balancing.

What to do if the disc does not fit on the hub?

If the center hole of the disc is larger than 66.1 mm, use adapters. They can be ordered for a specific size (for example, 73.1→66.1 mm for Toyota wheels). Important: rings must be made of aluminum or steel, plastic ones are not suitable!

Common mistakes when choosing disks and how to avoid them

Even experienced car owners sometimes make mistakes when selecting wheels for Nissan Cefiro A33. Let's look at typical mistakes:

1. Ignoring departure (ET).

   Installing disks with ET20 (for example, from Nissan 350Z) will cause the wheel to move outward, which will increase the load on the wheel bearings and worsen handling.

2. CO mismatch without adapters.

   Discs with CO 73.1 mm (for example, from Toyota Camry) will not sit on the hub Cefiro without adapter rings. Balancing such wheels will be impossible.

3. Incorrect selection of bolts.

   Bolts from Nissan Almera N16 (with thread M12×1.5) will not fit - the thread pitch is different! This will cause the bolts to “break” when tightened.

How to avoid mistakes:

• 🔍 Check the markings on the back of the disc (for example, 5×114.3 ET40 66.1).
• 🔍 Check manufacturers' catalogs (for example, BBS, Enkei, Rays).
• 🔍 Before purchasing, “try on” the disc on the hub (even if the parameters are the same).

⚠️ Attention: On some Cefiro A33 with all-wheel drive (4WD) hubs with different offsets are used. Check this with the previous owner or in the service book!

Tuning and non-standard solutions

For those who want to highlight their Nissan Cefiro A33, there are several ways to upgrade wheels:

• 🔥 Wheel arch extension — allows you to install disks up to width 9.5J with departure ET15.
• 🔥 Installing spacers - increases the track, but requires elongated bolts and can affect the suspension life.
• 🔥 Zero offset wheels — visually make the car wider, but require modifications to the suspension.

Examples of tuning configurations:

Style	Discs	Rubber	Modifications
JDM	R17 8J ET30	215/40 R17	Spacers 15 mm, rolling arches
Stance	R18 9J ET15	225/35 R18	H&R springs, castor bushings
OEM+	R16 7.5J ET40	215/50 R16	No modifications

Important to remember:

• ⚠️ Spacers thicker than 20 mm require replacing the hub bolts with elongated ones (for example, M12×1.25 40mm long).
• ⚠️ Rims too wide (9.5J+) may affect shock absorbers or suspension arms.
• ⚠️ Low profile tires (40 and below) reduces comfort and increases the risk of damage to discs in pits.

FAQ: Frequently asked questions about the Nissan Cefiro A33 bolt pattern

Is it possible to install wheels from Nissan Skyline R34 on Cefiro A33?

Yes, but with reservations. U Skyline R34 same bolt pattern 5×114.3 and CO 66.1 mm, however, departure to R34 often ET30–ET40. If the disc overhang is less ET35, possible contact with the calipers or suspension. Please check rim width and diameter compatibility before purchasing.

What bolts are needed for Cefiro A33?

Standard bolts are threaded M12×1.25 and length 27–30 mm. Non-standard rims (such as those with spacers) may require bolts up to 40 mm. Important: Use only bolts with cone fit (type Mag Seat), since flat washers will not provide reliable fixation.

What happens if you install 73.1 mm rims without adapter rings?

The disc will sit on the hub, but will not be centered on it. This will result in:

• 🔧 Steering wheel vibrations at speed.
• 🔧 Incorrect balancing (even after the procedure on the machine).
• 🔧 Accelerated wear of wheel bearings.

Solution: Use centering rings (adapters) 73.1→66.1 mm.

What is the maximum diameter of discs that can be installed without modifications?

Without modifications to the suspension and arches, the maximum safe diameter is - R17 with rubber 215/45 R17 and departure ET35. For R18 you will need:

• 🔧 Reducing overhang to ET30.
• 🔧 Using low-profile rubber (for example, 225/40 R18).
• 🔧 It is possible to trim the fender liners (with the width of the rim 8J+).

Will wheels from Infiniti Q45 (1990–1996) fit Cefiro A33?

No, despite the same PCD 5×114.3, y Infiniti Q45 overhang is often used ET25–ET35 and CO 67.1 mm. To install on Cefiro you will need:

• 🔧 Adapter rings 67.1→66.1 mm.
• 🔧 Spacers for adjusting offset (if ET < 35).

However, even with adapters there may be problems with balancing and increased load on the bearings.
