Bolt Pattern Converter
Select a metric bolt pattern to see the inch equivalent.
Please select a metric PCD.
Wondering if a particular wheel will fit your car? Convert any metric bolt pattern (like 5×114.3) to its inch equivalent (5×4.5″) in a flash with the Bolt Pattern Calculator. Just choose your pattern and get the results with the right wheel bolt pattern calculator!
Quick Answer
A bolt pattern is typically written as [lug count] × [circle diameter]. Such a pattern can be expressed in two formats:
- Metric: 5×114.3
- Standard (inches): 5×4.5″
They represent the same thing. Our calculator instantly translates between these two, so you can easily find the perfect match for any listing regardless of the format used.
Common Bolt Pattern Conversion Chart
| Metric | Inches | Common Vehicles |
| 4×100 | 4×3.94″ | Honda Civic, VW Golf |
| 5×100 | 5×3.94″ | Subaru WRX, Toyota Corolla |
| 5×112 | 5×4.41″ | Mercedes, Audi, Volkswagen |
| 5×120 | 5×4.72″ | BMW, Chevy Camaro |
| 6×135 | 6×5.31″ | Ford F-150 |
| 6×139.7 | 6×5.5″ | Chevy Silverado, GMC Sierra, Toyota Tacoma |
| 8×165.1 | 8×6.5″ | RAM 2500, Silverado HD |
How to Use the Calculator
TheBolt Pattern Calculator makes the math easy. Here is how it works:
- Choose the bolt pattern in the first selection — such as 4x100mm, 5x120mm, 5x150mm, 6×139.7mm,8x170mm or 8x180mm from the first dropdown
- View the converted result — the application instantly shows the inch equivalent, e.g., 4.5″. Make a comparison with your vehicle wheel installation requirements before purchasing.
You may also start from an inch measure and convert it to metric. Either way is fine.
How to Measure Your Bolt Pattern
In case your car is not listed anywhere or you have an older or modified one, measure it yourself:
4, 6, or 8-lug wheels: Measure directly from the center of one hole to the center of the very opposite hole. This is your PCD.
5-lug wheels: Since no two holes lie directly opposite to each other, take the measurement from the center of one hole to the center of an adjacent hole, then multiply by 1.701.
For a precise result, use digital calipers. Repeat your measuring twice or thrice to be sure, and then enter the value into the calculator to get the standard format.
Similar Bolt Patterns That Are Not the Same
Some patterns look almost identical in metric but are completely different fitments. Do not assume they are interchangeable:
| Pattern A | Pattern B | Difference | Compatible |
| 5×114.3 | 5×112 | 2.3mm | No |
| 6×139.7 | 6×135 | 4.7mm | No |
| 5×100 | 5×98 | 2mm | No |
| 4×100 | 4×98 | 2mm | No |
Even a 2mm mismatch means the wheel will not seat flush on the hub. Always verify the exact PCD before purchasing.
Bolt Pattern Is Not Enough: Other Fitment Checks
The first condition is to fit the bolt pattern. However, besides ordering, you should also check:
Center bore — This is the larger center hole in your wheel, and it must match the size of your hub. No way to mount the wheel if it is smaller. If it is larger, you will need to use hub-centric rings to eliminate vibration.
Wheel offset (ET) — This is a measure of how much the wheel will protrude or recede. An incorrect offset may cause the wheels to rub against the fenders or create clearance issues with the suspension.
Backspace — the distance from the mounting surface to the inner lip — is very important for brake caliper clearance, especially on larger vehicles like trucks.
Lug seat type refers to the types of contact between lug and wheel, including conical, ball seat, and flat/flanged, which are not interchangeable. Even if the bolt pattern is correct, a mismatched lug seat will significantly reduce clamping efficiency.
Common Wheel Bolt Patterns by Vehicle Type
Passenger cars include most Japanese and Korean models, which use a 5×114.3 bolt pattern. European manufacturers mostly use 5×112 (VW, Audi, Mercedes) or 5×120 (BMW). Small economy cars generally adopt 4×100.
Examples of bolt patterns for trucks and SUVs include: the Ford F-150 with 6×135; GM trucks (Silverado, Sierra, Tahoe) and the Toyota Tacoma/4Runner with 6×139.7; and heavy-duty trucks such as the RAM 2500 and Silverado HD with 8×165.1.
Performance and sports vehicles, for example, the Ford Mustang, share a 5×114.3 bolt pattern with many Japanese vehicles. Chevy Camaro uses 5×120, which is also used by BMW, making their wheels mutually compatible for shopping.
Find the Right Wheel with Kipardo
Once you’ve determined your exact bolt pattern, purchasing fitment-verified wheels from most major platforms is a breeze with Kipardo.
If Japanese builds require 5×114.3, European fitments require 5×112, or trucks require 6×139.7, you can rest assured that Kipardo’s forged and flow-formed wheels are designed to match these specifications precisely — no adapters, no guesswork. Use the free wheel bolt pattern calculator and ET Change Calculator to complete your fitment check, then contact Kipardo’s team to discuss wheel sourcing, bulk orders, or custom PCD options.

Frequently Asked Questions
Can I use wheels with a slightly different bolt pattern?
Ideally, no. Shifting the PCD by as little as 2mm still causes your wheel to not align perfectly with the hub, causing the studs to experience uneven stress. So, to be safe, always stick to the exact PCD when choosing wheels.
