Selection of rims for Nissan Almera generation N16 requires careful attention to the technical specifications of the car. Errors in the selection of parameters can lead to vibrations, accelerated wear of wheel bearings and even loss of control at high speed. Bolt pattern is just one of the key factors, along with center bore diameter and wheel offset.
Owners often ignore the nuances of suspension design, trying to install discs from other models or with an increased radius without taking into account the geometry. For Nissan Almera N16 Factory tolerances are strictly regulated, and their violation is unacceptable. In this article we will analyze all the technical parameters that you need to know when replacing standard wheels.
Basic bolt pattern and CO parameters for Almera N16
The key parameter that determines the compatibility of a disc with a car is PCD (Pitch Circle Diameter), or bolt pattern. For Nissan Almera in the N16 body this figure is 4x100. This means that there are 4 mounting holes on the disk, the diameter of the circle passing through their centers is 100 millimeters.
The second critical parameter is Central hole (CO or D). On standard disks for Nissan Almera N16 this size is exactly 60.1 mm. It is this that ensures the centering of the wheel relative to the hub. Bolts or nuts only press the disk, but do not keep it from moving. If you are installing a disc with a larger hole diameter, be sure to use adapter rings.
It is necessary to take into account wheel offset (ET). For this model, the standard reach range is from 35 to 45 mm. Reducing the overhang (for example, up to 25 mm) moves the wheel outward, which can lead to touching the arch or causing wheel alignment problems. Increasing the offset, on the contrary, places a lot of stress on the hub bearing.
⚠️ Attention: Installation of disks with a central hole diameter greater than 60.1 mm without the use of adapter rings is strictly prohibited. Vibration during movement will be transmitted to the suspension, which will lead to rapid destruction of the wheel bearing.
Sometimes owners wonder whether they can use wheels from other Nissan models. For example, from Nissan Primera or Bluebird. The answer depends on the specific PCD and CO parameters. Even if the bolt pattern matches, differences in offset or hole diameter can make installation impossible or dangerous.
Dimensions of bolts and nuts for fastening wheels
In addition to the geometry of the disk itself, it is critical to choose the right fasteners. For Nissan Almera N16 threaded bolts or nuts are used M12x1.25. The thread pitch of 1.25 mm is the standard for Japanese cars of this class.
The length of the fastener also matters. The standard bolt has a threaded length sufficient to fully engage in the hub. If you are installing a wheel with a long offset, the standard bolts may not screw in all the way. If the disc has a shorter offset, the long bolts may push against the brake caliper or hub, causing damage.
The heads of the bolts or nuts are of a spanner size 21 mm. This is a standard size found on most domestic and foreign cars. When purchasing new wheels, be sure to check that the delivery kit includes suitable fasteners that match the parameters M12x1.25.

Acceptable tire and wheel sizes
The manufacturer recommends for Nissan Almera N16 Several configuration options depending on the engine and equipment. Basic versions are often equipped with steel wheels of size R14 or R15. Sports or richer trim levels may have alloy wheels R16.
The most popular tire sizes for this model: 175/70 R14, 185/65 R15 And 195/55 R16. When choosing a size, you need to pay attention to the overall diameter of the wheel. If you choose to install larger tires, this may cause the speedometer to display incorrect data and the ABS and ESP readings may become incorrect.
The width of the rim must also match the width of the tire. For profile 175 optimal disc width 5.5J or 6J. For tire width 195 a disk width would be better 6J or 6.5J. A rim that is too narrow for a wide tire will result in profile deformation, while a rim that is too wide will result in unstable handling.

Compatibility and Specifications Table
For ease of selection, we have collected the main parameters in one table. These data are reference data for all modifications of the N16 body, including sedans and hatchbacks. Deviations from these values require consultation with a suspension specialist.
| Parameter | Meaning | Unit of measurement | Note |
|---|---|---|---|
| Bolt Pattern (PCD) | 4x100 | pcs x mm | Standard for N16 |
| Central hole (CO) | 60.1 | mm | Be sure to use rings when magnifying |
| Departure (ET) | 35-45 | mm | Optimal 38-42 |
| Fastener thread | M12x1.25 | mm | Thread pitch 1.25 |
| Key size | 21 | mm | For nuts and bolts |
⚠️ Attention: When using adapter rings for alignment, make sure that their height does not exceed the permissible value, otherwise the disc may touch the brake system elements when turning the steering wheel.
Features of installation and operation
Mounting wheels on Nissan Almera N16 requires compliance with the bolt tightening sequence. It is recommended to use a cross-shaped tightening pattern. This will ensure an even fit of the disc to the hub and prevent it from distorting. The tightening torque should be approximately 100-110 Nm.
If you are installing wheels with an increased offset or width, be sure to check that they do not touch the suspension elements when the steering wheel is turned completely. It's also worth checking to see if the inside of the disc is touching the brake caliper or shock absorber. Sometimes this requires the installation of spacers.
Regular checking of bolt tightness after changing wheels is mandatory. In the first 50-100 kilometers, it is necessary to check the tightening again, since the metal can “shrink” under load. This is especially true when changing seasonal tires.
☑️ Check before travel
Typical mistakes when selecting disks
One of the most common mistakes is using wheels from other car brands that technically have a bolt pattern. 4x100. For example, some models Volkswagen or Opel have the same PCD, but the diameter of the central hole may be different 57.1 mm or 56.6 mm. In such cases, the disc simply will not fit onto the hub without boring or rings.
Another mistake is ignoring the design of the braking system. On Nissan Almera N16 Depending on the configuration, there may be different calipers. The disc from the version with disc brakes at the rear may not fit the version with drum brakes due to different disc depths or hub shape.
Sometimes owners try to save money by using used wheels without checking their geometry. Even slight deformation of the disc can cause severe vibration on the steering wheel and body. Always test the disc on a balancing machine before installation.
- ❌ Ignoring the diameter of the CO (60.1 mm).
- ❌ Using wheels with the wrong offset (ET).
- ❌ Installation without checking for runout and balancing.
What to do if the disc does not fit on the hub?
If the disc does not fit onto the hub, check the diameter of the center hole. If it is less than required, the disc will have to be bored, which may upset its balance. If it is larger, use adapter rings. Also check to see if there is any rust or dirt on the hub that is interfering with the fit.
Recommendations for choosing cast and stamped wheels
The choice between stamped and cast wheels depends on your goals and operating conditions. Stamped discs are cheaper and dampen vibrations better, but they are heavier. For the winter period of operation on Nissan Almera N16 Stamping is often recommended, as it more easily withstands impacts from obstacles hidden under the snow.
Alloy wheels are lighter in weight, which improves acceleration dynamics and reduces the load on the suspension. They also look more aesthetically pleasing and allow for a more aggressive design. However, with a strong impact, a cast disk can crack or split, while a stamped one will simply bend, which can be easily fixed.
Regardless of the type of disc, make sure it has the required markings. The parameters must be indicated on the inside of the disk PCD 4x100, ET And CO. Lack of labeling or discrepancy with the data specified in the passport is a reason to refuse the purchase.
Before purchasing discs, measure the diameter of the brake caliper with a caliper. This will help avoid a situation where the new disc simply won't fit into place due to insufficient space for the caliper.
Proper selection of offset (ET) and center hole (CO) is more important than the appearance of the disc. Errors in these parameters directly affect the safety and life of the suspension.
FAQ: Frequently asked questions
Is it possible to install wheels with a 4x108 bolt pattern on the Almera N16?
No, that's impossible. The 4x108 bolt pattern is different from the stock 4x100. The holes for the bolts will not line up and the wheel will not be able to be secured. The use of spacers with overdrilling is highly discouraged due to the risk of disc destruction or wheel loss.
What is the maximum radius of disks that can be installed on Almera N16?
The factory provides a maximum R16. Installing disks R17 or higher will require serious modifications to the suspension, arches and selection of low-profile tires, which can negatively affect comfort and safety.
Are spacers needed to install wheels?
Spacers are only needed if you want to increase the vehicle's track or if the selected rims have too little offset (ET). The spacers must be of high quality and securely attached to the hub.
Why does the steering wheel vibrate on new wheels?
This can be caused by improper balancing, a defective disc, or the disc not being centered on the hub (unless adapter rings were used when installing a large CO disc). Check the disk geometry and balancing quality.
Can I use bolts from other machines?
No. The bolts must match the threads exactly M12x1.25 and length. Using improper fasteners may cause the threads to strip or the wheel to become loose while driving.
