What car uses 4 137 bolt pattern?
Very few mainstream cars use a 4x137 bolt pattern; it’s a rare, niche specification seen mainly in limited-market models or aftermarket wheel builds.
What is a 4x137 bolt pattern?
A 4x137 bolt pattern means there are four lug holes arranged on a circle with a diameter of 137 millimeters (about 5.39 inches). It’s far less common than 4x100, 4x114.3, or 5x114.3 patterns, so wheels and adapters for 4x137 can be scarce. When dealing with any nonstandard pattern, it’s important to verify center bore size and wheel offset to ensure proper fitment and safe mounting.
How it compares to other 4-lug patterns
Most 4-lug patterns you’ll encounter are 4x100, 4x114.3, or 4x120. The 4x137 layout uses a larger bolt circle, which affects stud reach and hub compatibility. Some manufacturers and aftermarket sellers label it as 4x5.39in; conversions or adapters exist, but they are not universal and can impact ride quality and safety if misapplied.
Where you might encounter it
Below are the kinds of scenarios where a 4x137 pattern has appeared, though it is not common on modern mass-market passenger cars. The items below describe potential contexts rather than naming specific models.
- Limited-run or regional-market vehicles and trucks that adopted 4x137 for a particular generation or export variant.
- Aftermarket wheel catalogs and conversion kits that list 4x137 compatibility for custom builds, off-road rigs, or show cars.
- Historic, concept, or specialty vehicles that experimented with nonstandard bolt patterns.
In practice, if you’re trying to source or fit 4x137 wheels, you’ll likely rely on aftermarket options. Always verify hub bore, lug thread size, and center bore compatibility, and be aware that some patterns may require adapters that can affect safety and warranty.
How to identify your vehicle’s bolt pattern
Before attempting to source wheels or adapters, confirm your exact bolt pattern with careful measurement and cross-checks.
- Count the number of lug holes on the wheel mounting face (common counts are 4 or 5).
- Measure the bolt circle diameter (BCD): measure from the center of one lug hole to the center of the opposite lug hole, then multiply by two for a 4-lug pattern.
- Check the center bore diameter to ensure hub-centric compatibility with your vehicle.
- Cross-check your measurement against the vehicle manufacturer’s specifications or a reputable wheel database to confirm whether the pattern is truly 4x137.
If you find a close-but-not-exact measurement, consult a professional technician to confirm fitment before ordering wheels or adapters, as small discrepancies can lead to improper seating or safety issues.
What to do next
For anyone investigating a 4x137 fitment, prioritize accuracy and safety. When in doubt, stick with widely supported bolt patterns or rely on wheels explicitly rated for your vehicle by the manufacturer. If you’re pursuing a custom build, work with a qualified tire and wheel shop to select approved adapters, spacers, and wheel specifications that maintain proper clearance and load capacity.
Summary
The 4x137 bolt pattern is an uncommon specification for passenger cars, largely confined to niche markets and aftermarket applications. Accurate verification of bolt pattern, center bore, and offset is essential. For most buyers, standard, well-supported bolt patterns remain the safer and more reliable choice, while 4x137 should be pursued only with professional guidance and reputable sources.
