Ram 1500 bolt pattern & lug nut torque
Lug pattern, hub bore, stud thread and torque for every 1500 generation from 2002–2026 — plus which other trucks the wheels can move to.
2019–2026 · 5th gen (DT)
6x139.7
also written 6x5.5"
Torque is the value commonly published for this generation, not a substitute for your owner's manual. Tighten in a star pattern with a torque wrench and re-check after 50–100 miles.
1500 bolt pattern by year
The 1500 has changed pattern during its run, so the year matters more than the badge. Find your generation below.
| Years | Generation | Bolt pattern | Bore | Thread | Torque |
|---|---|---|---|---|---|
| 2019–2026 | 5th gen (DT) | 6x139.7 · 6x5.5" | 77.8 mm | M14 x 1.5 | 130 lb-ft |
| Ram went from five lugs to six for the 2019 DT. Wheels from a 2018 or older Ram 1500 do not fit, and this catches a lot of people out because both trucks were sold new side by side in 2019 as the "1500 Classic". | |||||
| 2002–2018 | 3rd–4th gen | 5x139.7 · 5x5.5" | 77.8 mm | M14 x 1.5 | 130 lb-ft |
Fitting wheels to a 1500
The pattern is the first of four checks, and the one people stop at. Here is the rest of it, in the order that matters.
- 1
Pattern — 6x139.7
6 studs on a 139.7 mm circle, sold as 6x5.5" in inch terms. This has to match exactly. A wheel one standard size out will start on two studs and then bind, which is how studs get stretched and cross-threaded.
- 2
Hub bore — 77.8 mm
The centre hole has to clear a 77.8 mm hub. Factory wheels match it exactly and let the hub carry the load. Aftermarket wheels are usually bored larger to fit several vehicles, and then need hub-centric rings — without them the studs carry the load and you get a vibration that no amount of balancing fixes.
- 3
Offset and width
Offset decides whether the tire clears the fender liner at full steering lock and the suspension at full compression. It is the check that catches people out after the pattern matches and the wheel bolts on happily in the driveway. Work out the change before you buy, not after the tires are mounted.
- 4
Load rating
Every wheel carries a maximum load stamped on the back. On a truck that tows or hauls this is not a formality — the rating has to cover your axle weight, and a passenger-car wheel in the right pattern is still the wrong wheel.
Torquing a 1500 wheel
Target 130 lb-ft on M14 x 1.5 studs, reached in two or three passes rather than in one go — roughly half, then three quarters, then full. Order: 1, 4, 2, 5, 3, 6 — always cross to the stud opposite, then step round one. Use a torque wrench for the final pass; an impact gun cannot be trusted to a figure and over-torquing warps brake rotors as reliably as under-torquing loses wheels. Re-check after 50 to 100 miles — new wheels seat slightly as they bed in, and that is when a nut goes slack. Your owner's manual is the authority if it gives a different number than 130 lb-ft.
Trucks that share the 6x139.7 pattern
These will bolt onto the same studs. Whether they fit depends on hub bore, offset and brake clearance — check all three before you buy a used set.
1500 wheel fitment — frequently asked
What is the bolt pattern on a Ram 1500?
The 2019–2026 Ram 1500 uses a 6x139.7 bolt pattern, also written 6x5.5", on a 77.8 mm hub bore. It has not always been this pattern — see the year-by-year table below, because wheels do not carry across the change.
What is the lug nut torque on a Ram 1500?
The commonly published figure for the 2019–2026 Ram 1500 is 130 lb-ft on M14 x 1.5 studs. Tighten in a star pattern in two or three stages with a torque wrench, never with an impact gun alone, and re-check after 50 to 100 miles whenever a wheel has been off. Your owner's manual is the authority if it disagrees.
What is the hub bore on a Ram 1500?
77.8 mm. Factory wheels match that exactly and are hub-centric, meaning the hub carries the load rather than the studs. Aftermarket wheels are often bored larger to fit several vehicles — those need centring rings to run true, and a wheel bored smaller than 77.8 mm will not go on at all.
Did the 1500 bolt pattern change over the years?
Yes. Across 2002–2026 the Ram 1500 has used 2 different patterns: 6x139.7 (2019–2026); 5x139.7 (2002–2018). Wheels do not carry across that change, and because overlapping model years often looked similar it is worth checking your own hub rather than going by the badge.
What other trucks share the 1500 bolt pattern?
On record, the 6x139.7 pattern is also used by the Chevrolet Colorado, Chevrolet Silverado 1500, Ford Ranger, GMC Canyon, GMC Sierra 1500, Nissan Titan. Sharing a pattern means the wheel will bolt on; it does not mean it will fit. Check hub bore, offset and brake clearance before moving a set of wheels between trucks.
Will any 6x139.7 wheel fit my 1500?
Not automatically. The pattern only gets the wheel onto the studs. The bore has to clear the hub, the offset has to keep the tire out of the fender and the suspension, and the load rating has to cover your axle weight — which matters more on a truck that tows than on a car.
