When it comes to modifying or restoring vehicles, understanding wheel bolt patterns is crucial for ensuring proper fitment and compatibility. Many people often find themselves wondering whether 6x139.7 is the same as 6x5.5, especially when shopping for wheels for trucks or SUVs.
What Do These Numbers Mean?
6x139.7: This is a metric measurement where ‘6’ refers to the number of bolts and ‘139.7’ is the diameter of the circle formed by the bolt holes in millimeters.
6x5.5: This is a standard measurement where ‘6’ again refers to the number of bolts, and ‘5.5’ is the diameter of the circle in inches.
Are They Interchangeable?
Yes! The two measurements are interchangeable. To clarify, 6x139.7 mm translates to approximately 6x5.47 inches. While the numbers are not identical, the slight difference is often negligible in practical applications, particularly in off-road and performance settings.
Why Does This Matter?
Compatibility: If you’re looking to swap wheels between vehicles that use these bolt patterns, knowing this equivalence can save you from making costly mistakes.
Availability: Sometimes you might find more options available in one specification than the other. Understanding this can widen your choices significantly.
Customization: For enthusiasts who love to customize or upgrade their vehicles, knowing your bolt patterns can help in sourcing the right parts more efficiently.
Final Thoughts
It’s great to double-check the specs when purchasing new wheels or tires. However, with 6x139.7 and 6x5.5 being effectively the same in this context, you can feel more confident about your wheel choices. If anyone has additional insight or personal experiences regarding wheel fitment conversions, sharing those would be really helpful too!

I have been wondering about the differences in bolt patterns too! It’s crucial to understand these measurements for wheel compatibility. 6x139.7 mm and 6x5.5 inches may seem similar, but they are not the same.
Just to clarify, 6x139.7 mm converts to 6x5.5 inches, but the spacing is slightly different. The metric measurement is more precise, while imperial can lead to a bit of confusion. It’s important to be exact!
For anyone confused about the measurements, the ‘6’ refers to the number of bolt holes, and ‘139.7’ or ‘5.5’ refers to the diameter of the circle they form. Understanding this makes things clearer!
I think there’s a lot of misinformation out there about bolt patterns. People often assume similar numbers mean compatibility, but that’s not the case at all.
Great question! Many Toyota trucks have the 6x139.7 pattern. Whereas, the 6x5.5 is common on some older Dodge and Jeep models. Real-world examples help a lot!
Remember, double-checking specs is key! I’ve seen people buy beautiful wheels only to find out they won’t fit their vehicle at all. Talk about a letdown!
On a lighter note, sometimes I wish cars came with a giant warning sign about bolt patterns! Just to save all of us a headache. Anyone else feel that way?
Just to reflect, understanding bolt patterns is more than just a number—it’s a matter of safety and performance. Always prioritize proper fitment for your vehicle.
The 6x139.7 and 6x5.5 bolt patterns are not interchangeable. The former is often found on vehicles like Chevy and GMC trucks, whereas 6x5.5 is primarily used on many older Toyotas and Nissan trucks. Always check compatibility!
That’s right, thomas30! I’ve got a Toyota Tacoma with a 6x5.5 bolt pattern, and I’ve been tempted to try wheels from my friend’s Chevy. Glad I double-checked before making a purchase!
