Choosing wheel rims for a car Nissan Sunny The FB15, released in 2000, requires extreme precision. An error in the fastener parameters can lead not only to the impossibility of installing the wheel, but also to a serious accident on the road. Many car owners confuse the parameters of this model with older or newer generations, which creates problems when purchasing.
The key factor here is the concept bolt patterns, which determines the geometry of the disk attachment to the hub. For Nissan Sunny FB15 these parameters are strictly fixed by the manufacturer and do not allow deviations. Understanding all the specifications will help you save time and money when searching for the right tires and alloy wheels.
In this article we will analyze each parameter in detail: from the number of bolts to the disc offset. You will learn how to correctly decipher the markings on disks and what to look for when purchasing a used vehicle. The safety of your movement directly depends on how accurately the wheels are selected.
Basic parameters of wheel rim mounting
The first thing you need to look at when selecting is PCD (Pitch Circle Diameter). For Nissan Sunny FB15 In 2000, this figure was 4×100. This means that there are 4 holes on the disk, the diameter of the circle passing through their centers is 100 millimeters. Any deviation of even 1-2 millimeters will make installation impossible or dangerous.
The second critical parameter is center hole diameter (DIA or CB). For this model it is 60.1 mm. This hole should fit snugly against the vehicle's hub, ensuring alignment. If you buy wheels with a large bore diameter, be sure to use adapter rings, otherwise the wheel will be centered only on the bolts, which will cause the steering wheel to wobble.
Also worth considering nut or bolt, used for fastening. In most cases for Nissan Sunny M12×1.25 threaded bolts are used. The bolt head is usually 21mm hexagonal. Incorrect selection of fasteners can lead to thread breakage or inability to tighten with the required force.
- 🔧 Number of mounting holes: strictly 4 pcs.
- 📏 Bolt diameter: 100 mm (PCD 4x100).
- ⭕ Center hole diameter: 60.1 mm.
- 🔩 Fastener thread: M12×1.25.
It is important to note that some owners try to install disks with the 4x114.3 parameter, which is a serious mistake. This bolt pattern is incompatible with the hub. Nissan Sunny FB15 without using serious adapters, which are highly not recommended.
⚠️ Warning: Never try to “bore” holes on the disc if they do not line up with the hub. This disrupts the geometry of the metal and will lead to the destruction of the disk while moving.
The influence of disc offset on handling
Parameter departure (ET or Offset) determines how much the rim mounting plane protrudes relative to the centerline of the wheel. For Nissan Sunny FB15 The standard reach range is from 35 to 45 mm. This value is critical for proper operation of the suspension and steering.
If you install wheels with a shorter offset (for example, ET 20), the wheel will protrude far beyond the arch. This will place additional stress on the wheel bearing and suspension arms, which will lead to their rapid wear. In addition, such a wheel can touch the fender when turning the steering wheel or driving over uneven surfaces.
On the contrary, too much offset (for example, ET 55) will “drown” the wheel inside the arch. This can lead to the disc hitting the elements of the brake system or shock absorber. In both cases, the run-in shoulder changes, which makes the car less stable on the highway and more sensitive to road irregularities.
- Standard (ET 35-45)
- Reduced (ET 20-30)
- Extended (ET 50+)

Some auto tuners tend to make the wheels “offset” for an aggressive appearance, but for Nissan Sunny this is not a good idea. The standard suspension of this model is designed for a certain range of loads, and a violation of the geometry will quickly affect comfort and safety.
- 📉 Minimum permissible overhang: 35 mm.
- 📈 Maximum permissible overhang: 45 mm.
- ⚙️ Standard parameter: ET 38 or ET 40 is most common.
When purchasing discs secondhand, always check the markings on the inside of the disc. The number “ET” before the number means departure. Ignoring this parameter is the most common cause of problems after changing wheels.
Acceptable tire and wheel sizes
The manufacturer has provided several configuration options for Nissan Sunny FB15 2000. Standard wheel sizes range from 13 to 15 inches in diameter. The choice depends on the vehicle configuration and engine power, but they all have the same 4x100 bolt pattern.
The most common size for this model is R14 with tires 185/65. This option provides the optimal balance between comfort, cross-country ability and operating costs. For more powerful versions or tuning, R15 wheels with low-profile tires are often installed.
The width of the rim (J) also plays a role. The standard width is 5.5J or 6.0J. Installing a rim that is too narrow or too wide can result in improper tire pressure distribution, reducing traction and accelerating tire wear.
| Disk size | Width(J) | Departure (ET) | Tire size |
|---|---|---|---|
| 13x5.5 | 5.5 | 35-40 | 175/70 R13 |
| 14x5.5 | 5.5 | 38-42 | 185/65 R14 |
| 15x6.0 | 6.0 | 35-45 | 195/55 R15 |
| 15x6.5 | 6.5 | 30-40 | 205/50 R15 |
Otherwise, the speedometer will show the wrong speed, and the on-board computer data will become unreliable.
⚠️ Attention: Installation of disks with a diameter of R16 and above for Nissan Sunny FB15 It is highly not recommended without serious modification of the suspension and body elements.
Instructions for checking compatibility upon purchase
If you are planning to purchase wheels from the aftermarket, you need to do a thorough check. Do not rely solely on the seller's words, as markings may be erased or incorrectly interpreted. The best way to ensure compatibility is to physically measure and try on.
Before going to the seller, prepare the necessary tools. You will need a caliper to accurately measure the hole diameter and an angle gauge or protractor to check the bolt pattern. It's also a good idea to have one of your old bolts with you to check the threads.
☑️ Disk checklist
Pay special attention to the condition of the mounting holes. They should not be oval or stretched. If the holes show signs of deformation, such a disk cannot be used, since the bolts will not be able to provide reliable clamping. Also check the plane of the disc for distortions.
When trying the disk on the hub, it should fit tightly, without play. If the disc is hanging on the bolts but not flush to the hub, the DIA or PCD settings are mismatched. Do not over-tighten the bolts to "fit" the disc - this may cause stripping of the threads.
- 🔍 Visual inspection: no cracks or chips.
- 📐 PCD measurement: the diameter of the hole circumference should be exactly 100 mm.
- ⭕ DIA measurement: center hole should be 60.1mm.
- 🔩 Checking the thread: the bolt should screw in completely without effort.
What to do if the disc doesn't fit a little?
If the central hole is larger than 60.1 mm, you can buy adapter rings (centralizers). If it is less, the disk will not fit, you will have to look for another one. If there is a slight difference in the PCD (by 0.5-1 mm), the disk may become skewed, which is dangerous.
Sometimes sellers offer wheels with parameters 4x100, but with a central hole of 54.1 mm or 56 mm. These discs are not suitable for Nissan Sunny, since the hub will not fit into the hole. In this case, you will need spacer rings, but it is better to immediately look for a disk with the correct diameter of 60.1 mm.
Before purchasing, measure the distance from the hub to the edge of the fender using a tape measure. This will help you determine if the new wheel will protrude beyond the arch, especially if you choose wheels with a shorter offset.
Nuances of winter operation and winter tires
Winter period of operation Nissan Sunny FB15 imposes its own requirements on the choice of disks. Owners often buy separate sets of stamped wheels for the winter, so as not to reflash the tires and protect the alloy wheels from reagents. The bolt pattern parameters must remain unchanged.
For winter, wheels of a smaller diameter, for example, R13 or R14, with a higher rubber profile are often chosen. This allows you to use softer winter tires that perform better on snow and ice. However, the offset and bolt pattern must strictly comply with factory standards.
It's important to consider that winter rims often have a simpler design and fewer spokes, making them easier to clear of snow and dirt. But at the same time they must withstand low temperatures without loss of strength. Aluminum alloys become more brittle in severe frosts, so the quality of the metal plays a big role.
- ❄️ Ideal size for winter: R13 or R14 with a high profile.
- 🛡️ Corrosion protection: stamped wheels require regular painting.
- 🔩 Tightening control: after installing winter tires, check the tightening of the bolts after 500 km.
Don't forget about seasonal changes in tire pressure. In winter, the pressure should be slightly lower than in summer to increase the contact area with the road. However, excessive pressure reduction can lead to disc deformation in the pits.
The winter set of wheels must have the same PCD, DIA and ET parameters as the summer set to avoid installation and safety problems.
Common mistakes when selecting wheels
One of the most common mistakes is to use spacers to change the offset. Although this is technically possible, for Nissan Sunny FB15 This is not recommended. Spacers increase the load on the wheel bearing and can lead to its destruction on uneven surfaces.
Another mistake is buying disks from other models Nissan, for example, from Almera or Pulsar. Despite the fact that they often also have a 4x100 bolt pattern, the diameter of the central hole may differ. For example, for some models it is 54 mm or 66 mm, which makes direct installation impossible.
You should also avoid wheels with non-standard mounting holes (such as those with slots instead of round holes) unless they are made specifically for your vehicle. These discs may not provide proper fit and tightening.
Is it possible to install wheels from Nissan Almera?
Only if the DIA (60.1 mm) and ET parameters match. If the hole diameter is different, adapter rings will be required, which is not desirable.
Some owners try to install wheels with a large number of bolts (for example, 5 bolts) using adapters. This is strictly not recommended, since adapters are often of poor quality and cannot withstand loads, which can lead to the wheel coming off.
When purchasing, always check the technical documentation. Don't take the word of salesmen who claim that "all 4x100 wheels are the same." The difference in center hole diameter and offset can be critical.
FAQ: Frequently asked questions
What is the bolt pattern of the 2000 Nissan Sunny FB15?
The bolt pattern is 4x100, that is, 4 holes with a circle diameter of 100 mm. The diameter of the central hole is 60.1 mm.
Is it possible to install wheels with an offset of ET 30 on a Nissan Sunny FB15?
Technically possible, but not recommended. An offset of 30mm will move the wheel outwards, which will increase the load on the wheel bearing and can lead to contact with the fender.
What bolts are needed for Nissan Sunny FB15?
Bolts with M12×1.25 thread are used. The length of the bolt depends on the thickness of the disc, but the standard length is about 30-35 mm.
Will wheels from Nissan Almera N16 fit?
No, they won't fit. The Almera N16 has a 4x100 bolt pattern, but the center hole diameter is often different (usually 54.1mm or 66mm), requiring the use of adapter rings, which are not recommended.
What to do if the disc is not centered on the hub?
If the disc does not center, it means that the diameter of the center hole does not match the diameter of the hub. It is necessary to find a disk with a diameter of 60.1 mm or use high-quality adapter rings, but it is better to avoid the latter option.
