If you are the owner Nissan Sunny in the back FB15 (1990-1995 model year) and are planning to replace wheels or tires, the first thing you need to do is deal with the bolt pattern. This setting determines which wheels will fit your vehicle without risking damage to the hub or suspension. An error in choice can lead not only to vibrations at speed, but also to emergency situations.
In this article we will analyze in detail standard bolt pattern parameters for Sunny FB15, compatibility with alternative wheel sizes, as well as the nuances of selecting tires for different operating conditions. We will pay special attention to tuning - what non-standard options can be installed without compromising safety.
What is a bolt pattern and why is it important for the Nissan Sunny FB15
Bolt pattern (or PCD — Pitch Circle Diameter) is the diameter of the circle on which the holes for attaching the wheel to the hub are located. For Nissan Sunny FB15 this parameter is strictly regulated by the manufacturer, and its violation is fraught with serious consequences:
- 🔧 PCD mismatch leads to an uneven fit of the disc, which causes the steering wheel to wobble and accelerated wear of the bearings.
- 🚗 Operation with incorrect bolt pattern may cause the wheel to come off at high speed.
- 💰 Hub damage - if the bolts are tightened skewed, the threads quickly break off and expensive repairs are required.
On Sunny FB15 The bolt pattern depends on the year of manufacture and modification. For example, models with an engine GA14DE or GA16DE may have different hub parameters. Next we will clarify these data.
If you buy used wheels, always check the PCD with a caliper - sellers often make mistakes in the specifications.
Standard bolt pattern Nissan Sunny FB15: official data
For most versions Nissan Sunny FB15 (1990–1995) the manufacturer indicates the following parameters:
| Parameter | Meaning | Note |
|---|---|---|
| Bolt Pattern (PCD) | 4×100 | 4 holes, circle diameter 100 mm |
| Center Hole Diameter (DIA) | 59.1 mm | May vary depending on year |
| Departure (ET) | 35–45 mm | Recommended range for standard drives |
| Mounting bolt thread | M12×1.25 | Standard for most Japanese cars of the 90s |
Important: on some export versions (for example, for the Southeast Asian market) it could be used PCD 4×114.3. This is rare, but before buying discs be sure to check the parameters using the VIN code or measure the hub yourself.
- Standard steel
- Cast
- Forged
- Tuning with non-standard offset
How to measure the bolt pattern on a Nissan Sunny FB15 yourself
If you are not sure about your vehicle's parameters, you can measure the PCD manually. To do this you will need a caliper or ruler. Follow the instructions:
- Remove the wheel and clean the hub from dirt.
- Measure the distance between the centers of two adjacent holes (for example,
A). - For a 4-bolt mount, multiply this value by
1.414(root of 2). The result is the desired PCD.
Example: if the distance between holes 70.7 mm, then PCD = 70.7 × 1.414 ≈ 100 mm.
☑️ Preparing to measure bolt pattern
⚠️ Attention: Don't rely on visual assessment - even a 1-2mm difference will render the disc incompatible. For example, PCD 4x98 (found on some Toyota) outwardly almost indistinguishable from 4x100, but installing such a wheel on Sunny FB15 it is impossible.
Compatible with rims from other cars
Due to the popularity of the bolt pattern 4×100 drives from Sunny FB15 interchangeable with many Japanese and European models. Here is a list of cars with identical parameters:
- 🚘 Nissan Pulsar N14/N15 (1986–1995)
- 🚗 Toyota Corolla E90/E100 (1987–1995, but check DIA)
- 🚙 Mazda Familia BG (1989–1994)
- 🚖 Honda Civic EG/EK (1991–2000, requires adapter for DIA)
- 🚕 Mitsubishi Lancer (90s)
However, there are nuances:
- 🔴 Center Hole (DIA): y Sunny FB15 it is 59.1 mm, and Honda Civic - 56.1 mm. Will be required centering rings.
- 🟡 Departure (ET): If it is very different from the standard, it will affect the load on the bearings.
What happens if you ignore the DIA mismatch?
Without centering rings, the disc will not be perfectly centered on the hub. This will lead to vibrations at speeds above 80 km/h and accelerated tire wear.
Selection of tires for Nissan Sunny FB15: sizes and recommendations
Standard tire sizes for Sunny FB15 depend on the configuration:
| Modification | Tire size | Disc diameter | Note |
|---|---|---|---|
| Basic (1.4/1.6) | 175/70 R13 | 13″ | The most common option |
| Sports (SR) | 185/60 R14 | 14″ | Improved handling |
| Tuning versions | 195/50 R15 | 15″ | Requires offset adjustment |
When choosing tires, consider:
- 🌡️ Seasonality: the optimal size for winter
175/70 R13with spikes or Velcro. - 🏁 Driving style: for aggressive driving, hard tires are suitable (for example, Yokohama Advan).
- 💧 Rain conditions: Models with deep grooves (e.g. Michelin Energy) drain water better.
⚠️ Attention: Installing tires with a larger diameter 15″ will require modification of the arches or changes in ground clearance. On Sunny FB15 this is fraught with friction against the wheel arch liners when fully loaded.
Wheel tuning: what non-standard sizes are suitable
For tuning lovers Sunny FB15 offers ample opportunities, but with caveats:
- 🔥 Wheels R16: can be installed with a recess
ET30–38and tires205/45 R16, but it will require rolling out the arches. - ⚡ Low profile tires: for example,
215/40 R17- only for rides, as comfort will deteriorate sharply. - 🎨 Colored wheels: popular shades gunmetal or gold, but they require regular maintenance to prevent corrosion.
An example of a successful tuning combination:
Диски: 15×7J ET35 (PCD 4×100, DIA 59.1)Шины: 195/50 R15 (например, Toyo Proxes T1R)
Дополнительно: проставки 15 мм (если нужен более широкий колесный диск)
When tuning, never sacrifice safety for appearance. Even if the discs are visually suitable, check them on a balancing machine - an imbalance of more than 50 grams is unacceptable.
Common mistakes when choosing disks and how to avoid them
Owners Sunny FB15 often encounter typical problems:
- Buying discs with PCD 4×114.3 by mistake. They will not physically fit, despite the visual similarity.
- Ignore departure (ET). Too much or too little overhang leads to premature wear of the wheel bearings.
- Savings on centering rings. Without them, the disc will not be perfectly centered, which will cause vibration.
How to avoid mistakes:
- 📋 Always check with disk manufacturer catalogs (For example, BBS or Enkei).
- 🔍 Check disks for availability certificates of conformity — fakes often have inaccurate geometry.
- 🛠️ When installing new disks, be sure to do wheel alignment — even a minimal change in offset affects the angles.
FAQ: Answers to popular questions
Is it possible to install 4x114.3 wheels on the Sunny FB15 using adapters?
Technically yes, but this not recommended. Adapters increase the load on the hub and can become deformed during sudden maneuvers. If there is no alternative, choose adapters made of aluminum alloy with a certificate and a thickness of at least 20 mm.
What is the maximum disk diameter that can be installed without modifications?
Without modification of arches and suspension, the maximum safe size is - R15 with tires 195/50. For R16 you will need to roll out the arches or use spacers with a negative offset (but this worsens handling).
What should I do if vibration appears after replacing the disks?
The reasons may be different:
- Incorrect balancing - return to tire shop.
- DIA Misalignment - Install centering rings.
- Bent disk - check on a bench.
If vibration appears at speeds above 100 km/h, the problem is most likely in imbalance or deformed hub.
Which bolts are suitable for rims on Sunny FB15?
Standard bolts are threaded M12×1.25 and length 25–28 mm. For alloy wheels it is better to use bolts with cone fit (for example, art. Nissan 40500-4M000). When installing spacers, you will need extra long bolts.
Where can I find original wheels for Sunny FB15?
Original steel wheels Nissan you can search:
- At Japanese auctions (for example, Yahoo! Auctions Japan).
- In groups of Sunny FB15 on Facebook or Drive2.
- From official dealers Nissan Classic Parts (if left in stock).
The price of used original discs usually does not exceed 3–5 thousand rubles. per piece.
