The Isuzu D-Max is one of the most popular pickups on the German market. Those looking to upgrade their D-Max with new Isuzu D-Max rims quickly face technical questions: What bolt pattern does the D-Max have? Which offset is permissible? Do rims from a Hilux or Ranger fit? In this guide, we answer all relevant questions about Isuzu D-Max rims and provide concrete recommendations to help you find the optimal rim.
Isuzu D-Max Rim Basics: Bolt Pattern and Dimensions by Generation
The D-Max bolt pattern is consistently 6x139.7 mm across all generations — six bolts on a bolt circle diameter of 139.7 millimeters. This bolt pattern is widely used in the pickup segment and offers an excellent selection of compatible rims. Learn more in our article about 6x139.7 Rims.
A crucial factor is the hub bore (center bore). The older generation (up to 2020, RT series) has a hub bore of 108.1 mm, while the new generation (from 2021, RG series) has one of 106.1 mm. The difference is minimal but relevant for correct centering: Rims with too large a bore can be retrofitted with centering rings, but too small bores will not fit. You can find basic information on this in our article about Bolt Patterns for Rims.
The wheel nuts use a thread size of M12x1.5 with a tightening torque of 120 Nm. Only use the prescribed tapered or spherical lug nuts that match the rim type. From the factory, Isuzu supplies the D-Max with 16-, 17- or 18-inch rims in widths from 6.5J to 7.5J. The standard offset is ET 33, with 15-inch steel rims sometimes having ET 41.
Old vs. New Generation (Up to 2020 vs. From 2021): What Has Changed?
The 2021 generation change brought extensive modifications to the chassis and technology. For rim selection, the differences are minor — the 6x139.7 bolt pattern remained identical. Nevertheless, there are important details:
| Feature | Old Generation (RT, up to 2020) | New Generation (RG, from 2021) |
|---|---|---|
| Bolt Pattern (PCD) | 6x139.7 mm | 6x139.7 mm |
| Hub Bore | 108.1 mm | 106.1 mm |
| Wheel Nuts | M12x1.5 | M12x1.5 |
| Standard Rim Sizes | 15, 16, 17, 18 inch | 16, 17, 18 inch |
| Standard Offset | ET 33 to ET 41 | ET 33 to ET 41 |
| Standard Tire Sizes | 215/70 R15 to 255/60 R18 | 245/70 R16 to 265/60 R18 |
| Brake System | Compact, more clearance | Larger front brake discs |
| Chassis Geometry | Conventional | Optimized, wider track |
| Model Years | 2012 to 2020 | 2021 to present |
Rims from both generations are largely compatible, provided the bolt pattern is correct and the center bore fits. The difference between 108.1 mm (RT) and 106.1 mm (RG) is minimal. In practice, most aftermarket rims use a larger center bore and are supplied with suitable centering rings, ensuring compatibility in both directions.
Important: Isuzu increased the brake system on the RG model, so 15-inch rims no longer fit over the brake caliper. From 16 inches upwards, there are no problems. The new generation also has a wider track from the factory — pay attention to fender clearance with rims with a low offset.
Rim Sizes: 17 vs. 18 vs. 20 Inch for the D-Max
The choice of rim size depends on the intended use. The most common aftermarket sizes are 17, 18, and 20 inches.
17-inch rims are considered the best compromise between everyday use and off-road. Tires like 265/65 R17 offer a decent sidewall with excellent damping on unpaved roads. The selection of all-terrain and mud-terrain tires is largest in 17 inches. Typical width: 7J to 9J, offset ET 0 to ET 33.
D-Max 18-inch rims are the most popular choice for a sportier look with solid off-road capability. Common tire dimensions: 265/60 R18 or 275/65 R18. The smaller sidewall allows for more direct steering and better road holding. D-Max off-road rims in 18 inches offer a wide range of aggressive designs. Typical width: 7.5J to 9J.
20-inch rims are for maximum presence. With tires like 275/55 R20, the D-Max looks imposing, but ride comfort decreases, and the off-road tire selection is significantly smaller. For serious off-road use, we recommend 17 or 18 inches.
Rule of thumb: The more off-road use, the smaller the rim diameter. Our range of Isuzu D-Max Rims includes all sizes from 17 to 20 inches.
Offset: Which ET Values Fit the D-Max?
The offset (ET) determines how far the rim is positioned inward or outward, directly affecting track width, appearance, and driving dynamics. The standard ET is ET 33, and for smaller rims, it's ET 41.
For D-Max off-road rims, ET values between ET -12 and ET 20 are popular. Lower ET values move the rim further outward, resulting in a wider track and improving tilt stability off-road. Proven ranges:
- ET 25 to ET 33 (close to standard): No adjustments needed, different design with the same look.
- ET 10 to ET 25 (moderately wider): Noticeable track widening, usually possible without fender flares. Most common range for all-rounders.
- ET -12 to ET 10 (significantly wider): Distinct widening, fender flares generally required.
- ET below -12 (extremely wide): Only with wide fender flares and individual approval.
If the ET changes by more than 2 mm compared to the standard value, registration may be required. Details can be found in our guide to TÜV Registration of Rims.
Same Bolt Pattern as Hilux and Ranger — Are All Rims Compatible?
D-Max, Hilux, and Ranger share the 6x139.7 bolt pattern — but the bolt pattern is only one of several parameters.
The Toyota Hilux has a hub bore of 106.1 mm (current generation) — identical to the new D-Max. Rims for the Hilux generally fit directly on the RG D-Max. For the older RT D-Max (108.1 mm), a centering ring is necessary. Toyota Hilux Rims therefore offer interesting options for D-Max drivers as well.
For the Ford Ranger (models up to 2022 and from 2023), the hub bore is only 93.1 mm. Ford Ranger Rims therefore have a too small center bore for the D-Max. Conversely, D-Max rims with centering rings fit the Ranger.
In addition to the hub bore, offset, rim width, and load capacity must also match. The wheel nuts also differ: The D-Max uses M12x1.5, the Ranger uses M12x1.5 or M14x1.5 depending on the generation. Universal off-road rims with 6x139.7 and a hub bore of 110 mm or larger fit all three vehicles — with vehicle-specific centering rings.

TÜV and Registration: Special Features for the D-Max
Non-standard rims must be registered in Germany. Driving without approval risks operating license, fines, and insurance coverage. Detailed information in our guide Registering Rims with TÜV.
There are three ways: An ABE (General Operating Permit) is the easiest — registration is uncomplicated and quick. A parts certificate according to §19 StVZO requires an inspection of mounting and clearance by an expert. The individual approval according to §21 StVZO is the most complex option for rims without European certificates — an expert checks strength, material, and suitability. Costs vary depending on the testing organization (TÜV, DEKRA, GTÜ, KÜS) and effort.
D-Max-specific points: The D-Max is approved as a commercial vehicle (N1), which means stricter requirements for load capacity. The rear axle load can be up to 1,400 kg depending on the model — not all off-road rims are designed for this. The permissible gross vehicle weight reaches up to 3,050 kg, which is why experts particularly carefully check the wheel load approval. Always pay attention to the load index of the rim and ensure that the manufacturer specifies an approval for the maximum axle load of your D-Max.
Our tip: Get advice before purchasing from TÜV, DEKRA, or GTÜ on whether the desired combination can be registered.
FAQ — Frequently Asked Questions about Isuzu D-Max Rims
What is the bolt pattern of the Isuzu D-Max?
The Isuzu D-Max has a consistent bolt pattern of 6x139.7 mm across all generations. This applies to the first generation (RA/RC, 2002-2012), the second (RT, 2012-2020), and the current third generation (RG, from 2021). This bolt pattern is also used by Toyota Hilux, Mitsubishi L200, and many other pickups.
Do Toyota Hilux rims fit the Isuzu D-Max?
Basically yes, as both share the 6x139.7 bolt pattern. The current Hilux and the D-Max from 2021 have an identical hub bore of 106.1 mm. For the older D-Max (108.1 mm), centering rings should be used. Also check offset, width, and load capacity. Toyota Hilux Rims are therefore often attractive for D-Max drivers as well.
What is the best rim size for off-road?
17 inches is the optimal off-road size. The higher tire sidewall offers more damping, better rim protection, and the largest selection of off-road tires. With 265/65 R17 or 285/70 R17, you achieve a balanced ratio of off-road capability and road comfort. D-Max 18-inch rims are a good compromise between appearance and off-road performance.
What offset do I need for wider tires?
For tires 275 mm wide or more, you need a lower ET than the standard ET 33. The range ET 0 to ET 20 offers enough space and an appealing track widening. For 285 mm or wider with ET below 0, fender flares are necessary. Have the clearance checked before mounting.
Do I need TÜV registration for new D-Max rims?
Yes, if the rims are not listed in the vehicle registration. Rims with ABE are easiest to register. For rims with a parts certificate, an installation inspection by an expert is required. Without a certificate, individual approval according to §21 StVZO remains — the most complex and expensive option. The specific costs depend on the testing organization and the effort. Without valid registration, the operating license expires.
Conclusion: The Right Rim for Your Isuzu D-Max
The Isuzu D-Max, thanks to its common 6x139.7 mm bolt pattern, is a grateful vehicle for rim upgrades. When choosing, pay attention to the correct hub bore (108.1 mm for the old generation, 106.1 mm for the new generation), the appropriate offset, and sufficient load capacity. With the right rims, you can get the maximum out of your D-Max both visually and functionally.
