You have found the perfect set of wheels. The look is right. The aggressiveness is perfect. The price is almost reasonable. Then you get to the bolt pattern and the listing says 5x114.3 but your car is 5x115. They are only 0.7mm apart. Surely that is close enough? Unfortunately not. Bolt pattern is the one wheel specification that must match exactly, and understanding why that matters is worth doing before you start shopping.
What is Bolt Pattern
Bolt pattern, also called PCD (Pitch Circle Diameter) or bolt circle, is the measurement that describes how many lug holes your wheel has and the diameter of the circle those holes form. The bolt pattern is expressed as the number of lugs followed by the diameter of the circle in millimeters. A 5x120 bolt pattern means there are 5 lug holes and they sit on a circle that is 120mm in diameter. An 8x170 pattern means 8 lug holes arranged on a 170mm circle.
The bolt pattern must match between the wheel and the vehicle hub exactly. There is no wiggle room here the way there is with offset or tire width. If the pattern does not match, the wheel will not mount safely. Some bolt holes might line up, but not all of them, and that is not good enough. The number of lugs is easy to count. The diameter of the circle is where things get interesting, particularly when you are trying to measure it yourself.
How to Measure Bolt Pattern
If you know your vehicle’s bolt pattern from the manufacturer specs, you can skip this section. If you are measuring a wheel or hub and do not know what the pattern is, the measurement process depends on whether you have an even number of lugs or an odd number of lugs.
4-Lug, 6-Lug, and 8-Lug Patterns
Even-lug patterns are the simplest to measure. For wheels with an even number of lugs, measure straight across from the center of one lug hole to the center of the hole directly opposite. That measurement in millimeters is your PCD.
If you have a 6-lug wheel and you measure 139.7mm from center to center across opposite holes, you have a 6x139.7 bolt pattern. The only trick here is making sure you are measuring to the center of the hole, not the edge. A set of calipers makes this easier than a tape measure, but either works if you are careful.
5-Lug and 7-Lug Patterns
Odd-lug patterns require a different approach because there is no hole directly across from any other hole. The geometry is more complex, and some trigonometry is involved.
For 5-lug wheels, measure from the center of one lug hole to the back edge (the far side, not the near side) of the lug hole two positions away. If you number the holes 1 through 5 going clockwise, you would measure from the center of hole 1 to the back edge of hole 3. That measurement, multiplied by 1.701, gives you the PCD.
Here is an example. If you measure from the center of one hole to the back edge of the hole two positions over and get 70.5mm, multiply by 1.701 to get 119.9mm. Round to 120mm and you have a 5x120 bolt pattern.
For 7-lug wheels, which are rare but do exist on some heavy-duty trucks, the same technique applies but the multiplier is different. Measure from the center of one hole to the back edge of the hole two positions away, then multiply by 1.414.
The multipliers come from trigonometry. The angle between two adjacent lug holes on a 5-lug wheel is 72 degrees (360 / 5). The relationship between the chord length you are measuring and the circle diameter involves some geometry that is outside of the scope of this article. Just remember 1.701 for 5-lug and 1.414 for 7-lug.
The Easy Way
If the idea of measuring to the back edge of a hole two positions over and multiplying by a trigonometric constant sounds tedious, you are right. The easier way is to look up your vehicle’s bolt pattern in the owner’s manual, on a wheel database website, or by searching your year, make, and model plus “bolt pattern” in your favorite search engine. Unless you are dealing with an unknown wheel or a custom hub, this is faster and more accurate than measuring.
Common Bolt Patterns by Manufacturer
Bolt patterns are not exactly random. Manufacturers tend to use the same patterns across multiple models and sometimes across decades. Knowing the common patterns for your make can help you identify wheels that will fit without measuring. That said, bolt patterns can vary even within the same manufacturer depending on the platform, the year, and the market. A Honda Civic from 1995 has a different bolt pattern than a Honda Civic from 2018. Always verify the pattern for your specific vehicle before assuming it matches.
Understanding which manufacturers share bolt patterns can significantly expand your wheel options. If you drive a BMW with 5x120, you can potentially shop wheels designed for the Tesla Model S, modern Chevy Camaro, or Cadillac. If you have a Honda with 5x114.3, you have access to the massive wheel market for Nissan, Mazda, Toyota, and Subaru. This cross-platform compatibility is particularly useful when shopping used wheels or looking for enthusiast-focused designs that were made for a different platform but happen to share your bolt pattern. Just remember that bolt pattern is only one spec and you still need to verify offset, centerbore, and width will work for your application.
Here are some of the most common bolt patterns grouped by manufacturer and vehicle type.
Passenger Cars
Audi / Volkswagen: 5x112 is the dominant pattern for Audi and VW. This includes the Golf, GTI, Jetta, A3, A4, A6, and most of the VW Group lineup. Older and smaller models sometimes used 5x100 or 4x100.
BMW: 5x120 is the standard for most modern BMWs including 3 Series, 5 Series, and M cars. Older BMWs used 5x120 as well, though some vintage models ran 4x100.
Dodge / Chrysler: 5x115 is the standard for most modern Dodge and Chrysler vehicles including the Charger, Challenger, 300, and Durango.
Ford (Cars): 5x108 is used on most modern Ford passenger cars including the Focus ST, Focus RS, Fiesta ST, and Fusion. This pattern is less common and makes wheel selection more limited.
GM (Cars): 5x120.65 (also written as 5x4.75”) was the traditional Chevy pattern for Camaro and Corvette. Modern GM coupes and sedans now typically use 5x120. The Chevy Volt and Bolt use 5x105.
Honda / Acura: 5x114.3 (also written as 5x4.5”) is extremely common. This includes the Accord, Civic (2006 and later), CR-V, TLX, and most Acura models. Older Civics and smaller Hondas used 4x100.
Mazda: 5x114.3 is used on most modern Mazda vehicles including the Miata (NC and ND), Mazda3, Mazda6, and CX-5. Older Miatas (NA and NB) used 4x100.
Nissan / Infiniti: 5x114.3 is the standard for most Nissan and Infiniti vehicles including the 350Z, 370Z, GT-R, G35, G37, Q50, and Altima. Some older or smaller models used 4x114.3 or 5x100.
Subaru: 5x114.3 is the current standard for WRX, STI, and most modern Subarus. Older models used 5x100, which is a common source of confusion when shopping for wheels for older Impreza-based models.
Toyota / Lexus: 5x114.3 is common on larger models like the Camry, IS, GS, and Supra. Smaller vehicles like the Corolla and 86 use 5x100. Trucks use 6-lug patterns.
Trucks and SUVs
Trucks and SUVs typically use 6-lug or 8-lug patterns depending on the size and duty rating.
Chevy / GMC Trucks: 6x139.7 (also written as 6x5.5”) is the classic Chevy truck pattern used on Silverado 1500, Colorado, Tahoe, and Suburban. The HD models (2500, 3500) use 8x180 (also written as 8x7.09”).
Ford Trucks: 6x135 is used on the F-150. The Super Duty (F-250, F-350) uses 8x170.
Jeep: 5x127 (also written as 5x5”) is the traditional Jeep pattern for Wrangler and Gladiator. The Grand Cherokee uses 5x127 on some trims and 5x5.5” on others depending on the year. Older Jeeps used 5x114.3.
Ram: 5x139.7 is used on the 1500. The 2500 and 3500 use 8x165.1 (also written as 8x6.5”).
Toyota: 6x139.7 is the standard for Tacoma, 4Runner, and older Tundras. The current Tundra uses 6x135. The Land Cruiser uses 5x150.
These are generalizations. Even within a single model, the bolt pattern can change between years or trims. Always verify your specific vehicle before assuming the pattern matches.
Why 5x114.3 and 5x115 Are Not Interchangeable
This is the part that trips people up and leads to bad decisions. You find a wheel in 5x115 and your car is 5x114.3. The difference is 0.7mm. Less than a millimeter. Surely the bolts will just pull it into place?
No. Even a small mismatch in bolt pattern means the lug holes on the wheel will not align with the studs or bolts on the hub. When the pattern is off by even a fraction of a millimeter, only one or two of the five lugs will line up and thread properly. The others will be slightly misaligned. If you force the lugs, you can strip the threads on the studs, crack the wheel around the lug holes, or most likely create a situation where the wheel is not properly clamped to the hub.
The best case is you realize it does not fit and you return the wheels. The worst case is you force it, drive on it, and the wheel comes loose or fails. Bolt pattern is not a spec you can fudge. The same applies to other near-miss patterns. 5x100 and 5x112 are not interchangeable. 5x120 and 5x120.65 are not interchangeable. 6x135 and 6x139.7 are not interchangeable. If the numbers do not match exactly, the wheels do not fit.
Wobble Bolts Are Not the Solution
Your cousin Fred might suggest using wobble bolts (also called tuner bolts or conical seat bolts with floating washers) to mount wheels with slightly mismatched bolt patterns. The idea is that the tapered seat and floating washer can compensate for small alignment differences. This is a bad idea for several reasons.
Wobble bolts are designed to adapt different lug seat types (ball seat vs conical seat), not to correct bolt pattern mismatches. When used to force a mismatched pattern, the lug bolts are fighting against the geometry of the wheel and hub instead of clamping them together properly. The wheel will never be truly centered on the hub, which creates an imbalance that can lead to vibration. The clamping force is compromised because the bolts are at an angle instead of perpendicular to the mounting surface. Over time, the constant stress can cause the bolts to work loose, the lug holes in the wheel to elongate or crack, or the wheel to separate from the hub entirely.
The fact that wobble bolts exist and that some people have used them for this purpose does not make it safe or correct. If your bolt pattern does not match, please use a proper bolt pattern adapter or buy wheels that fit.
There are only two legitimate ways to mount a wheel with the wrong bolt pattern. One is to use a bolt pattern adapter. The other is to redrill the wheel, which is a machining process that creates new lug holes in the correct location. Redrilling is expensive, not all wheels can be safely redrilled, and it voids any warranty or certification the wheel had. It is typically a last resort for vintage or custom applications, not a common solution for a modern street car.
Dual-Drilled Wheels
Some wheels are designed to fit multiple bolt patterns by having two complete sets of lug holes. These are called dual-drilled or multi-lug wheels and are commonly found for 4x100 / 4x114.3 and 5x100 / 5x114.3.
Dual-drilled wheels are a convenience solution for the manufacturer that allows one wheel design to fit a wider range of vehicles, but they come with aesthetic and functional compromises. The most obvious compromise is that you will have extra unused lug holes visible on the wheel face or barrel. Some wheels are designed to minimize this visually, but you will always be able to see the extra holes.
The functional compromise is that dual-drilled wheels often require longer lug bolts or studs to ensure proper thread engagement, since the wheel barrel has twice as many holes drilled through it and may be thicker in that area to maintain structural integrity. Always verify the required lug bolt or stud length when mounting dual-drilled wheels.
Dual-drilled wheels are more common in the budget and mid-range wheel market. High-end forged wheels are almost never dual-drilled because the target customer is willing to buy a wheel that is specifically engineered for their platform and does not want the visual compromise of extra holes.
Measuring in Inches vs Millimeters
Bolt patterns are typically expressed in millimeters in the modern wheel industry. However, if you are measuring a wheel or hub with a tape measure, you might get the measurement in inches. Converting between the two is straightforward.
To convert inches to millimeters, multiply by 25.4. To convert millimeters to inches, divide by 25.4. Some common bolt patterns have inch equivalents that you will see referenced, particularly in the American truck market:
- 5x114.3mm = 5x4.5”
- 5x127mm = 5x5”
- 5x139.7mm = 5x5.5”
- 6x139.7mm = 6x5.5”
- 5x120.65mm = 5x4.75”
- 8x165.1mm = 8x6.5”
- 8x180mm = 8x7.09” (sometimes rounded to 8x7.1”)
Bolt Pattern Adapters and Their Limitations
Bolt pattern adapters, also called wheel adapters, are thick machined spacers that bolt to your existing hub and provide a different bolt pattern for the wheel to mount to. If your car has a 5x120 pattern and you want to run wheels with a 5x114.3 pattern, an adapter can make that possible.
Adapters are a compromise solution and come with real trade-offs. They add unsprung weight, they change your effective offset by pushing the wheel outboard, they put additional stress on your wheel bearings and suspension, and they introduce an additional failure point between the hub and the wheel. That does not mean adapters are inherently unsafe, but they should be approached with these factors in mind and treated as a last resort when no other wheel option will work.
The thickness of the adapter depends on the design. Some adapters are relatively thin (15mm to 25mm) and use extended lug bolts or studs that go through both the adapter and the wheel. Other adapters are thicker (30mm or more) and have their own studs pressed into the adapter, so the wheel bolts directly to the adapter rather than using extended lugs. Thicker adapters are generally considered safer because they eliminate the risk of the extended lugs bottoming out before the wheel is fully clamped.
If you decide to use adapters, buy them from a reputable manufacturer that machines them from billet aluminum and has proper load testing and certification. Cheap cast adapters from unknown manufacturers are a roll of the dice. You are trusting this part to keep your wheel attached to your car. Do not skimp.
Proper installation of adapters is critical. The adapter must be torqued to the hub using the vehicle’s specified lug torque. The wheel must then be torqued to the adapter using the wheel manufacturer’s specified torque. After the first 50 to 100 miles, both sets of bolts should be re-torqued to ensure they have not loosened. Some adapters require periodic re-torquing as part of regular maintenance.
The other consideration is that adapters will push your wheel outboard by the thickness of the adapter. A 25mm adapter effectively lowers your offset by 25mm. If your car was running ET35 wheels and you install a 25mm adapter, the effective offset is now ET10. This can cause the wheel to stick out past the fender or rub on the fender during suspension travel. You need to account for this offset change when choosing wheels to run with adapters.
Adapters also add rotating mass. Every bit of weight you add to the wheel assembly increases the rotational inertia, which makes the suspension work harder and reduces acceleration and braking performance. For a street car this is a minor compromise. For a track car or performance application it is something to think about.
The final limitation of adapters is that they can affect hub-centric fitment. Many adapters are not hub-centric on both sides, meaning the adapter may not center perfectly on your vehicle hub or the wheel may not center perfectly on the adapter. This can lead to vibration if the installation is not precise. Using hub-centric rings on one or both sides of the adapter can solve this, but it adds complexity.
In short, adapters work and they are used successfully by many people, but they are not a free pass to run any wheel you want. Use them only when necessary, buy quality parts, install them correctly, and understand the trade-offs.
You did it. You got to the end. Amazing. Now you know how to measure bolt patterns, why a 0.7mm mismatch is not close enough, and what trade-offs you are making if you go the adapter route. Have a burning question you want answered in a guide? Email us at hello@rimlist.com.
