Why 5×139.7 Is the Same as 5×5.5
I’ve found this to be necessary because both measurements describe the same wheel bolt pattern, just in different units. The “5” means there are five lug holes, and the number after it is the bolt circle diameter. In metric, 139.7 mm is equal to 5.5 inches, so 5×139.7 and 5×5.5 are the same fitment.
I like knowing this because it helps me avoid confusion when shopping for wheels or checking vehicle specs. Some brands and listings use metric, while others use imperial, but the actual wheel pattern does not change. That means a wheel labeled 5×139.7 should fit the same vehicles as one labeled 5×5.5, as long as the other wheel specs also match.
For me, understanding this equivalence is important for getting the right wheels without making a costly mistake. It saves time, makes comparisons easier, and gives me confidence that I’m looking at the correct bolt pattern no matter which unit system is used.
My Buying Guides on 5×139.7 Same As 5×5.5
What I Learned About 5×139.7 and 5×5.5
When I first started shopping for wheels, I noticed both 5×139.7 and 5×5.5 being used in listings. I found out that these two bolt patterns are the same. The metric size 5×139.7 converts to the imperial size 5×5.5, so if my vehicle uses one, it can usually fit wheels listed in the other measurement as long as the rest of the specs match.
Why I Check the Bolt Pattern First
For me, bolt pattern is the first thing I verify before buying wheels. If the bolt pattern does not match, the wheel will not bolt onto the hub correctly. Even though 5×139.7 and 5×5.5 are equivalent, I still make sure the listing is accurate and not mixed up with a similar pattern.
Vehicles That Commonly Use This Pattern
I’ve seen this bolt pattern on several trucks and SUVs. Some common examples include:
- Jeep models
- Older Dodge trucks
- Some Ford trucks and SUVs
- Various off-road and utility vehicles
Still, I always double-check my exact year, make, and model because fitment can vary.
Other Wheel Specs I Never Ignore
Even when the bolt pattern matches, I know there are other details that matter just as much:
- Center bore — I check that the wheel fits the hub properly.
- Offset — I make sure the wheel sits correctly inside the wheel well.
- Wheel width — I confirm it supports my tire size.
- Load rating — I look for a wheel that can handle my vehicle’s weight.
My Tips for Buying the Right Wheels
Here’s what I do before I place an order:
- I confirm the bolt pattern is 5×139.7 or 5×5.5.
- I compare the center bore to my hub size.
- I check offset recommendations for my vehicle.
- I review tire size compatibility.
- I read s to see if other buyers had fitment issues.
What I Watch Out For
I’ve learned not to assume every wheel labeled 5×139.7 will fit perfectly. Sometimes the issue is not the bolt pattern but the offset, hub bore, or brake clearance. I also avoid buying wheels without clear fitment information, because a small mismatch can cause vibration or installation problems.
My Final Thoughts
From my experience, 5×139.7 and 5×5.5 are the same bolt pattern, so I can treat them as interchangeable in wheel shopping. But I never rely on bolt pattern alone. I always check the full wheel specs to make sure I get a safe, proper fit for my vehicle.
Final Thoughts
I hope this clears up the confusion around 5×139.7 and 5×5.5. In my experience, the key takeaway is that they are the same bolt pattern, just expressed in different units. That means if one is listed as 5×139.7, it should also match a 5×5.5 setup as long as the rest of the wheel specifications are correct.
