The 5x5.5 inch (or 5x139.7mm) bolt pattern is primarily used on older American trucks, classic Jeeps, and specific imported SUVs. Key vehicles include F-150s (1959-1996), Dodge Ram 1500s (1980-2010), Jeep CJ models, Suzuki Samurai/Sidekick, and the first-generation Kia Sportage. It's crucial to distinguish this pattern from the more common 5x5 (5x127mm) and to check center bore compatibility.
This bolt pattern, expressed as 5x5.5 inches (5 lugs on a 5.5-inch circle) or its exact metric equivalent 5x139.7mm, was a standard for light-duty trucks and SUVs in the late 20th century. Its application spans several major manufacturers.
Ford utilized this pattern extensively on its full-size trucks and SUVs. The iconic F-150 used it from its inception in 1959 through the 1996 model year. The Ford Bronco (1966-1996) and many full-size vans from the same era also share this lug pattern.
Dodge/Ram pickup trucks adopted the 5x5.5 pattern starting with the 1980 model year for the Ram 1500 (including the Ramcharger SUV) and continued its use through the 2010 model year for certain configurations, making it a defining feature for a 30-year production run.
Jeep's legendary CJ-5, CJ-7, and CJ-8 Scrambler models, produced from 1955 to 1986, all came with this bolt pattern. This makes it a critical specification for owners of classic off-road Jeeps seeking replacement wheels.
Japanese and Korean manufacturers also employed this pattern. Suzuki models like the Samurai, Sidekick (and its Geo/Chevrolet Tracker twins), Vitara, and Jimny commonly use it. The first-generation Kia Sportage (1993-2002) is another notable vehicle with a 5x139.7mm bolt pattern.
A critical compatibility note involves the center bore (hub bore) diameter. While a Dodge Ram and an old Ford F-150 share the same 5-lug pattern, their hub center sizes are different. Ford typically used a larger center bore. Using wheels without proper hub-centric rings can lead to vibration and improper load distribution, even if the lugs bolt on.
It is essential to differentiate 5x5.5 from 5x5. The 5x5 (5x127mm) pattern is entirely different and is found on modern Jeep Wrangler JKs, Grand Cherokees (WJ onward), and many GM half-ton trucks. Industry data shows that confusing these two similar-sounding patterns is a common error leading to incorrect wheel purchases.
The table below summarizes the primary vehicle applications:
| Manufacturer | Key Models (Years) | Notes |
|---|---|---|
| Ford | F-150 (1959-1996), Bronco (1966-1996), F-250 (pre-1999), Full-size Vans | Check center bore vs. Dodge. |
| Dodge/Ram | Ram 1500 (1980-2010), Ramcharger (1974-1993) | Dominant pattern for late 20th-century models. |
| Jeep | CJ-5, CJ-7, CJ-8 (1955-1986) | Standard for classic, leaf-sprung Jeeps. |
| Suzuki | Samurai, Sidekick, Vitara, Jimny, X-90 | Also applies to rebadged Geo/Chevrolet Tracker. |
| Other | Kia Sportage (1993-2002), International Harvester Scout | Early SUVs often shared this pattern. |
When sourcing wheels, always verify both the bolt pattern (5x139.7mm) and the vehicle-specific center bore requirement to ensure a safe and proper fit.

I’ve been restoring a 1989 Ramcharger for years, so I live and breathe the 5x5.5 pattern. It’s the heart of the wheel setup for my truck and tons of others from that era. If you’re hunting for aftermarket wheels for an older Dodge, Ford, or Jeep, this is the number you need to know.
Just remember, “5x5.5” is the same as “5x139.7mm”. Don’t let the mix of inches and millimeters trip you up. The biggest headache I see is folks mixing up this pattern with the 5x5 pattern on newer trucks. They won’t fit, so double-check your vehicle’s specs before you buy anything.

As a mechanic in a shop that handles a lot of older 4x4s, I explain this daily. The 5-on-5.5 pattern is like a fingerprint for a generation of vehicles. If you drive an F-150 from the ‘80s, a from the ‘90s, or an old Jeep CJ, your wheels are almost certainly 5x139.7mm.
The practical tip I give every customer is this: the bolt pattern is only half the battle. You must also match the center bore. A wheel from a Ford might slide onto a Dodge’s studs, but if the center hole is too big, the wheel isn’t centered properly. That causes shakes at speed and stresses the lug nuts. Always use the correct hub-centric rings for a perfect fit. It’s a small part that prevents big problems.

Looking for wheels for my 1995 Sidekick was a lesson in this specific bolt pattern. It’s not just an American thing. My Sidekick, along with the Geo Tracker, Samurai, and even the old Kia Sportage, all use 5x5.5 (139.7mm). It opens up cool options—sometimes you can find take-off wheels from an older Dodge truck that fit with the right adapters or bore matching.
But the market gets confusing. Many online listings are wrong. I learned to physically measure my bolt pattern myself to be sure. It’s saved me from buying the wrong set twice. For us with these older, smaller SUVs, knowing this number is key to unlocking more wheel choices.

From a parts specialist perspective, the 5x139.7mm pattern represents a significant and active niche in the wheel market. Demand remains steady from owners of classic trucks and off-road vehicles who are updating their look or replacing corroded original wheels. The key to successful matching is understanding the three facets: bolt pattern, center bore, and offset.
While the lug pattern is shared, the hub center diameter is not standardized. applications generally require a wheel with a center bore of approximately 93.1mm, whereas Dodge applications need a bore around 77.8mm. This is a non-negotiable detail for fitment and safety.
Furthermore, the offset—how far the wheel mounts in or out from the hub—varies by vehicle. A wheel with the wrong offset can rub against suspension components or fenders. When searching, use your specific vehicle make, model, and year as the primary filter, then confirm the technical specifications against the wheel’s listing. This pattern’s longevity means high-quality reproductions are available, but verifying these three specs prevents the majority of compatibility returns we see.
