Comparing QUAD, RUGGED, and XJ07? Start with the exact wheel specification, then compare the designs. A four-spoke face or a different finish can change the look of a truck, but it does not answer the fitment question.
This is a source-based guide, not a road test or a fitment approval. Use the manufacturer links for current specifications and prices, and ask a qualified wheel specialist about your exact truck.
Identify the Setup Before Choosing the Design
Have the truck’s chassis code, year, current tire size, and suspension changes ready. Check bolt pattern, center bore, rim width, offset, nut seat, load information, and the tire maker’s approved rim-width range. Clearance needs checking on the vehicle, including at full steering lock and through suspension travel.
The specifications below are selected manufacturer entries checked on September 23, 2026. They are not a list of wheels approved for every kei truck. A matching diameter or 4×100 bolt pattern is not enough to establish compatibility.
QUAD: Compare the Exact Specification
QUAD uses a four-spoke design. MLJ currently lists the following dimensions; compare the exact row and the manufacturer’s application notes with your truck before ordering.
| Size | Bolt pattern | Inset | Center bore |
|---|---|---|---|
| 12×4.00B | 4/100 | +43 mm | 67.1 mm |
| 14×4.5J | 4/100 | +45 mm | 67.1 mm |
| 15×4.5J | 4/100 | +45 mm | 67.1 mm |
The official QUAD table also gives size-specific markings, load information, and application notes, including an exclusion for N-VAN e. Its Satin Black and Gloss Machined listings are not stock confirmations.
These photographs are design references. They do not establish a wheel’s fitment or its current availability.
RUGGED: Another Design to Compare
MLJ calls this model RUGGED. One entry in its current table is 14×5.0J, 4/100, inset +45 mm, with a 67.1 mm center bore. The table lists Satin Black for that specification and gives separate load and application information.
Use the official RUGGED table to distinguish it from the other bolt patterns and offsets in the range. The shared model name does not make those entries interchangeable.
XJ07: Similar Names, Different Applications
XJ07 comes in specifications for several vehicle types. In MLJ’s current table, the 12×4.00B +42, 13×4.00B +43, and 14×4.5J +43 entries use 4/100 and list JWL/JWL-T; the application notes include kei trucks.
The 15×4.5J +43 entry also uses 4/100, but MLJ lists JWL and a kei-passenger-car application for that row. Do not treat it as a confirmed kei-truck option. Check the current XJ07 specification and application tables rather than extending one row’s information to the whole range.
Compare finishes only after identifying a suitable specification. The photographs are not a complete catalog or an availability list, and we have not tested these wheels on a lifted truck.
Ask for a Quote for the Exact Wheel
Manufacturer list prices can change and are not the same as a delivered quote. This guide does not confirm stock, an importer, or a delivery date. Use the official product pages above, then ask the seller to identify:
- The exact model, size, bolt pattern, inset, and finish.
- Whether the quote is for one wheel or a set.
- Required nuts or other hardware, taxes, shipping, import charges, and installation.
- The fitment information available for your truck and the return conditions if compatibility cannot be confirmed.
Common Questions
Which model is best?
We have not road-tested or ranked these models. Compare their appearance, but make the purchase decision from the exact specification and a vehicle-specific assessment.
Does a wheel marking confirm fitment?
No. JWL and JWL-T relate to manufacturer assessment against the relevant Japanese technical standards; VIA has a separate registration system. Check the exact size’s markings and load information. They do not replace a fitment assessment or establish off-road performance.
Is QUAD still awaiting its January 2026 release?
The manufacturer’s current page lists product specifications and Japanese retail prices. This guide does not establish the actual release date or current stock. Ask a seller about availability in your location.
Where to Go Next
For a checklist and a message you can send to a seller, read the 12-inch wheel fitment checks and MATTE TWELVE specifications.

This article is for general information, not installation, mechanical, or vehicle-specific fitment advice. Compatibility depends on the exact vehicle, wheel, tire, hardware, load, and modifications. Consult a qualified wheel specialist before purchasing. We have not measured handling, ride comfort, fuel use, or off-road performance for these wheels.
