Japan Racing JR46

Buying Guide for Japan Racing JR46 Rims

The Japan Racing JR46 rims are among the more modern models within the Japan Racing range and are primarily aimed at drivers who want to combine a sporty look with modern rim technology. The model is characterised by a striking 5-Twin-Spoke Design and is offered in several dimensions and technical variants.

As the JR46 rim is available in different inch sizes, widths, bolt patterns, and offset variants, it is important to select the appropriate configuration for the respective vehicle. In this buying guide for the Japan Racing JR46 rims, we explain the most important technical parameters and show what to pay particular attention to when making your selection.

In the following overview, we will cover diameter, width, bolt pattern, and offset and explain the most important characteristics of the JR46 rim.

Design and Features of the Japan Racing JR46

The Japan Racing JR46 differs significantly from classic multi-spoke models like the JR30. Instead of many thin spokes, the JR46 features a modern 5-Twin-Spoke Design where five main spokes each split into two arms. This creates a more open appearance with clean lines.

The advantage of this design is not just aesthetic. The larger surface area between the spokes allows the brake system and callipers to be more visible, which is particularly appreciated on sporty vehicles or performance brake systems. At the same time, the more open design also makes cleaning the rim easier.

Another important point is the Flow Forming technology used in the JR46. This manufacturing process shapes the rim's barrel under pressure, making the rim lighter and at the same time more stable than classic cast rims. This makes the JR46 particularly suitable for drivers who value a combination of sporty appearance and optimised weight.

The highly concave construction of the JR46 also contributes to its sporty appearance. The spokes run directly from the outer rim edge inwards to the centre, creating a deep, dynamic look that is particularly noticeable on wider variants.

Available Sizes of the JR46 Rim

The Japan Racing JR46 rims are available in several diameters, covering a wide range of sporty vehicle types. On this page, you will find variants of the JR46 rim in 18 inch, 19 inch, and 20 inch.

Dimensions such as JR46 18 inch are often used on sporty compact cars or dynamic everyday vehicles. These sizes generally offer a good balance between ride comfort, weight, and sporty appearance.

Larger variants such as JR46 19 inch or JR46 20 inch, on the other hand, are often used on higher-performance vehicles or for projects where a particularly sporty and striking look is desired. A larger rim can significantly change the overall appearance of a vehicle, but it should always match the recommended tyre size and the vehicle's technical approval.

Width of the JR46 Rim and Tyre Choice

In addition to the diameter, the width of the rim also plays an important role in selecting the right variant. The Japan Racing JR46 is available in various widths, including, for example, 8, 8.5, 9, 9.5, 10, or 10.5 inches.

The rim width influences, among other things, which tyre width can be fitted. Narrower variants are often used for near-standard setups, while wider rims allow for a sportier look and are often combined with wider tyres.

For example, JR46 18 inch 8.5J or JR46 19 inch 9J are frequently used on sporty road vehicles. Wider variants such as JR46 19 inch 9.5J, JR46 20 inch 10J, or JR46 20 inch 10.5J, on the other hand, are more commonly used for performance or tuning setups.

Due to the highly concave construction of the JR46, this effect is particularly noticeable on wider variants. Depending on the combination of width and offset, a pronounced concave shape is created, giving the vehicle a particularly dynamic and sporty look.

Bolt Pattern and Vehicle Compatibility

Another important parameter when selecting the appropriate JR46 rim is the bolt pattern. This describes the number of mounting holes and the diameter of the circle on which these holes are located.

The Japan Racing JR46 rims are available in several bolt pattern variants, including, for example, 5x100, 5x105, 5x108, 5x110, 5x112, 5x114.3, 5x115, 5x118, or 5x120. Which variant is required depends on the specific vehicle model.

Additionally, the centre bore diameter also plays a role. For the JR46, the standard centre bore is 72.6 mm. For vehicles with a smaller hub diameter, corresponding spigot rings are used to ensure precise and vibration-free mounting of the rim.

The bolt pattern and the appropriate hub diameter must match the vehicle's technical specifications for the rim to be mounted correctly. 

Offset (ET) of the JR46 Rim

In addition to diameter, width, and bolt pattern, the offset (ET) also plays an important role in selecting the correct rim. The ET describes the distance between the wheel's centre line and the mounting surface of the rim on the hub.

The Japan Racing JR46 rims are available with various ET values, typically ranging from approximately ET15 to ET51. Different ET values influence the position of the wheel in the wheel arch.

A smaller ET value means the rim sits further outwards, while a larger ET value positions the wheel further inwards. The correct offset is crucial to ensure sufficient clearance from the brake system, suspension, and bodywork.

The appropriate JR46 ET variant should therefore always be chosen in combination with the vehicle type, rim width, and tyre size.

Colour Variants of the JR46 Rim

The Japan Racing JR46 rims are available in several colour variants, allowing for individual customisation of the vehicle's look. Depending on the version, different finishes are available, including, for example, Black, Bronze, Multicolor, as well as Silver or Grey.

The choice of colour primarily influences the visual impact of the rim on the vehicle. Darker variants such as JR46 Black often appear particularly sporty and complement modern vehicle designs well. Lighter or metallic finishes such as Silver or Grey, on the other hand, can create a more classic and elegant look.

Variants such as Bronze or Multicolor are also often used for sporty projects when a stronger visual contrast to the vehicle colour is desired. Which colour variant is the best fit ultimately depends on personal taste and the overall appearance of the vehicle.

JR46 Rims with CH Supplement

The Japan Racing JR46 rims offered here are supplied with a CH Supplement and mounting kit. This means that for many vehicle models, appropriate documentation is already available that can be considered during technical inspection.

The mounting kit typically includes the necessary fastening elements and spigot rings, allowing the rims to be fitted professionally.

As each rim variant can have different dimensions, widths, bolt patterns, and offset values, you should check which JR46 configuration is suitable for your specific vehicle before ordering. The 3D rim configurator can help you find suitable variants for your vehicle.

Price and Delivery Time of the JR46 Rims

The price of the Japan Racing JR46 rims can vary depending on the dimension, width, bolt pattern, and finish. Larger diameters such as JR46 19 inch or JR46 20 inch are generally more expensive than smaller variants, as they require more material and are often used on higher-performance vehicles.

Particularly wide variants or special finishes can also influence the price. Therefore, it is worthwhile to compare the different JR46 configurations and select the appropriate combination of dimensions and features.

Most variants of the JR46 rim have a delivery time of approximately 5 to 14 days, depending on the specific dimension and finish.

Individual Check Before Ordering

Regardless of whether your vehicle is in standard condition or has modifications, an additional compatibility check before ordering may be advisable.

If you have any uncertainties regarding offset, width, bolt pattern, or aspects relevant to the technical inspection (MFK), an individual check can be carried out in direct consultation with our team.

Via WhatsApp, you can contact us quickly and send us your vehicle model and the desired JR46 rim configuration. This allows technical and legal questions to be clarified before ordering, making the purchasing decision more transparent and secure.
