Ram 1500 Wheel Bolt Pattern & Lug Pattern Chart by Year – 2026 All Generations

The Ram 1500 wheel bolt pattern chart is not one-size-fits-all because Ram changed the half-ton lug layout by generation. Most older Dodge Ram and Ram 1500 trucks use a 5-lug pattern, while the fifth-generation Ram 1500 DT uses a 6-lug pattern.

The confusing year is 2019. A 2019 Ram 1500 Classic follows the older DS body style, while a 2019 new-body Ram 1500 follows the DT platform. That one model year is where many wrong wheel purchases happen.

Use the chart below before buying factory take-off wheels, aftermarket rims, spacers, or used wheel sets.

Ram 1500 Wheel Bolt Pattern Chart By Year

Use this Ram 1500 wheel bolt pattern chart before buying wheels, spacers, or take-off factory rims. The safest first check is lug count. If your truck has five lugs, it does not share the same direct bolt-on wheel pattern as a six-lug Ram 1500.

This chart gives the bolt pattern only. It does not guarantee full wheel fitment by itself.

You still need to check center bore, offset, wheel width, brake clearance, lug-seat style, and load rating. Those specs matter more when buying aftermarket wheels or swapping wheels between trims.

For older 5-lug examples, Truck Guider already covers the 2017 Ram 1500 lug pattern and the 2014 Ram 1500 lug pattern in separate year-specific guides.

What 5×139.7 And 6×139.7 Mean

The first number is the lug count, and the second number is the bolt circle diameter. In simple terms, 5×139.7 means five lugs arranged around a 139.7 mm circle.

The same pattern can also be written in inches. A 139.7 mm bolt circle is commonly rounded to 5.5 inches, so 5×139.7 is the same general pattern as 5×5.5. The newer 6×139.7 Ram 1500 pattern is also commonly written as 6×5.5.

Do not match only the 5.5 number. A 5×5.5 wheel and a 6×5.5 wheel do not interchange because the lug count is different.

This is why the 2019 model year needs a separate check before ordering wheels.

Why 2019 Ram 1500 Fitment Gets Confusing

The 2019 Ram 1500 is the year where many wheel-fitment mistakes happen. Ram sold two different half-ton trucks under the Ram 1500 name during the transition from the older DS body to the newer DT body.

The fifth-generation Ram 1500 DT arrived for the 2019 model year. The older fourth-generation DS platform continued as the Ram 1500 Classic, so both trucks can appear in searches and listings as “2019 Ram 1500.”

2019 Ram 1500 Classic

The 2019 Ram 1500 Classic is the older DS body style. It keeps the 5×139.7 bolt pattern used by 2009 to 2018 fourth-generation Ram 1500 trucks.

If the truck has five lugs, treat it as the older 5-lug fitment family. Do not order new-body DT wheels unless you have confirmed an adapter setup, and even then, adapters need careful inspection and torque checks.

2019 Ram 1500 DT

The 2019 Ram 1500 DT is the new-body fifth-generation truck. It uses the 6×139.7 bolt pattern.

If the truck has six lugs, older 5-lug Ram 1500 wheels will not bolt directly on. This matters when buying used wheels from a 2018 Ram 1500 or a 2019 Classic.

The easy field check is simple: count the lugs before buying. After that, confirm the door label, VIN, body style, and wheel specs with the seller.

Ram 1500 Lug Nut Size And Center Bore

Bolt pattern is only the first fitment check for a Ram 1500 wheel. The wheel also has to sit correctly on the hub and accept the correct lug hardware.

For most late-model Ram 1500 fitment listings, the common thread size is M14x1.5. Center bore is commonly listed around 77.8 mm for many Ram 1500 applications. Verify these numbers against your exact wheel, trim, and model year before ordering.

Hub-centric fitment means the center bore of the wheel matches the truck hub closely. That helps center the wheel properly before the lugs are tightened.

If an aftermarket wheel has a larger center bore, the seller may recommend hub-centric rings. If the bore is too small, the wheel will not seat on the hub.

Lug-seat shape also matters. Factory wheels and aftermarket wheels may use different lug-seat styles, so do not reuse lug nuts unless the wheel seller confirms they match.

Which Ram 1500 Wheels Interchange Safely

Wheel interchange depends on more than whether the bolt holes line up. A direct bolt-on swap needs the same bolt pattern, compatible center bore, safe offset, enough brake clearance, correct lug hardware, and adequate load rating.

Factory take-off wheels can be a good option when the body style matches. For older factory rim research, Truck Guider has a separate guide on 20 inch Dodge Ram factory rims.

Tire size can still break the fitment even when the wheel bolts on. A taller or wider tire can rub the fender liner, upper control arm, sway bar, or bumper area. For a model-specific example, see the 2014 Ram 1500 tire size guide.

How To Check Your Ram 1500 Bolt Pattern

The safest way to confirm your Ram 1500 bolt pattern is to verify the truck, not just the model year. Used trucks may have aftermarket wheels, adapters, suspension changes, or incorrect seller listings.

1. Count The Lugs
   Count the wheel studs or lug nuts first. Five lugs point toward the older 5×139.7 family. Six lugs point toward the newer 6×139.7 DT family.
2. Check The Body Style
   For 2019 and newer trucks, confirm whether it is a Classic DS or a new-body DT. The grille, interior, body panels, and VIN decoding can help identify the platform.
3. Confirm The Wheel Listing
   Match the wheel listing by year, body style, lug count, center bore, width, offset, and load rating. Do not rely on “fits Ram 1500” alone.
4. Measure The Pattern If Needed
   For a 5-lug wheel, measure from the center of one lug hole to the outer edge of the opposite lug hole. For a 6-lug wheel, measure center to center across opposite lug holes.
5. Verify Before Ordering
   Ask the wheel seller or tire shop to confirm fitment using your VIN or exact truck configuration. This is especially important for lifted trucks and used wheel sets.

Once the bolt pattern is confirmed, the next check is what usually causes rubbing: offset and tire size.

Common Ram 1500 Wheel Fitment Mistakes

Most Ram 1500 wheel mistakes come from treating bolt pattern as the whole fitment spec. The pattern only tells you whether the lug holes line up. It does not confirm the wheel will clear brakes, suspension, or fenders.

Buying By Model Year Only

A 2019 Ram 1500 can be a Classic DS or a new-body DT. The Classic uses the older 5-lug pattern. The DT uses the newer 6-lug pattern.

Always confirm the body style before buying wheels for a 2019 truck.

Matching 5.5 Inches Only

Both 5×5.5 and 6×5.5 use a 5.5-inch bolt circle, but the lug count is different. A 5-lug wheel will not bolt directly onto a 6-lug hub.

Read the full pattern, not only the second number.

Ignoring Center Bore

A wheel with the wrong center bore can create vibration or fail to seat properly. If the bore is larger than the hub, hub-centric rings may be needed. If the bore is smaller than the hub, the wheel will not fit.

This is why center bore must be checked before aftermarket wheel installation.

Ignoring Offset And Width

Offset controls where the wheel sits inside the fender. Too much negative offset can push the tire outward and cause fender rub. Too much positive offset can move the tire inward and create suspension clearance problems.

Wheel width and tire size change the result even more.

Assuming HD Wheels Fit A Half-Ton

Ram 2500 and Ram 3500 wheels should not be treated as automatic Ram 1500 upgrades. Heavy Duty trucks use different fitment requirements, and some wheels are built around different hub, load, and brake needs.

Check the full wheel spec before mixing half-ton and HD parts.

Best Next Step Before Buying Ram 1500 Wheels

Before you buy Ram 1500 wheels, confirm six specs instead of relying on one bolt-pattern number.

Use this checklist:

1. Year and body style
2. Lug count
3. Bolt pattern
4. Center bore
5. Lug nut thread and seat style
6. Wheel width, offset, tire clearance, and load rating

The Ram 1500 wheel bolt pattern chart gets you started, but the final fitment decision depends on the complete wheel package. Count the lugs, confirm the body style, then verify the specs with the wheel seller before you order.

Ram 1500 Wheel Bolt Pattern FAQ

What Is The Bolt Pattern On A Ram 1500

The Ram 1500 bolt pattern depends on the year and body style. Many older Dodge Ram and Ram 1500 trucks use 5×139.7, while the fifth-generation Ram 1500 DT uses 6×139.7.

What Bolt Pattern Is A 2019 Ram 1500

A 2019 Ram 1500 Classic uses the older 5×139.7 pattern. A 2019 new-body Ram 1500 DT uses the newer 6×139.7 pattern. Count the lugs before ordering wheels.

Is 5×5.5 The Same As 5×139.7

Yes, 5×5.5 and 5×139.7 describe the same general 5-lug bolt circle. One is written in inches and the other is written in millimeters.

Is 6×5.5 The Same As 6×139.7

Yes, 6×5.5 and 6×139.7 describe the same general 6-lug bolt circle. This is the common pattern used on fifth-generation Ram 1500 DT trucks.

Will 2018 Ram 1500 Wheels Fit A 2020 Ram 1500

No, not as a direct bolt-on swap. A 2018 Ram 1500 is typically 5×139.7, while a 2020 Ram 1500 DT is 6×139.7.

What Is The Center Bore On A Ram 1500

Many Ram 1500 fitment listings show a center bore around 77.8 mm, but you should verify it by exact year, body style, and wheel. Aftermarket wheels may need hub-centric rings if the bore is larger than the truck hub.

Can Ram 2500 Wheels Fit A Ram 1500

Do not assume Ram 2500 wheels fit a Ram 1500. Heavy Duty wheels can differ in bolt pattern, center bore, offset, brake clearance, and load-rating requirements. Verify the full wheel spec before trying any HD wheel swap.
