Jeep Wrangler Bolt Pattern by Generation: CJ, YJ, TJ, JK, JL and Gladiator

The Jeep Wrangler bolt pattern is 5×5 inches (5×127 mm) on the JK (2007 to 2018), the JL (2018 on) and the Gladiator JT (2020 on). The YJ (1987 to 1995) and TJ (1997 to 2006) use 5×4.5 inches (5×114.3 mm), and the CJ models built from 1945 to 1986 used 5×5.5 inches. So a TJ wheel will not bolt onto a JK, but a JK wheel lines up with JL and Gladiator hubs.

The bolt pattern is only one of four numbers that decide whether a wheel fits. The others are the hub bore, the lug stud thread and the offset. The JK and JL share the pattern but not the lug thread, and many JL wheels have an offset that will not clear a JK. The sections below go through each generation, the lug nut specs Jeep publishes, and what actually interchanges.

Bolt pattern, lug thread and torque by generation

The patterns come from wheel and adapter makers’ fitment data. Spidertrax lists its 5-on-4.5 to 5-on-5 adapter for the 1987 to 1996 YJ and 1997 to 2006 TJ, so they can run 2007 to 2018 JK wheels, and its CJ adapter converts a JK axle to the 1945 to 1986 CJ bolt circle. AEV’s Borah wheel lists a 5×5 pattern and a 71.5 mm hub bore for the JL and Gladiator, with a 0 mm offset version that also fits the JK. The lug thread and torque figures are taken from Jeep’s own owner’s manuals: the 2017 JK manual, the 2024 JL manual and the 2024 Gladiator and 2006 TJ manuals. Where Jeep has not published a figure we could check, the table says so. Look in the manual for your exact year rather than trusting a number from a forum.

5×4.5 vs 5×5: what the numbers mean

The first number is the lug count and the second is the diameter of the circle through the center of the studs. A 5×5 wheel has five holes on a 5-inch circle, which is 127 mm. A 5×4.5 wheel has five holes on a 4.5-inch circle, or 114.3 mm. The difference is only half an inch, and that is why people try to force the wrong wheel on. It will not seat flat, and studs pulled sideways can shear.

The CJ’s 5×5.5 pattern (139.7 mm) is larger again. CJ wheels do not fit a YJ or TJ, and they do not fit a JK or JL without an adapter.

On a five-lug wheel no two holes sit directly opposite each other, so a tape measure across the hub gives the wrong answer. The usual shortcut is to measure from the center of one stud hole to the outer edge of the hole two positions away, skipping the one in between. A bolt pattern gauge from an auto parts store is quicker and less error-prone, and the size stamped on the back of many wheels settles it.

Hub bore, offset and the other numbers that matter

Hub bore. The center hole of the wheel has to fit over the hub’s pilot. AEV lists a 71.5 mm hub bore for its Borah wheel, which it sells for the JK, JL and Gladiator. A wheel with a smaller bore will not mount, and a larger bore needs a hub-centric ring or relies on the lug nuts alone to center it.

Offset and backspacing. These decide where the tire sits relative to the fender, brakes and suspension. AEV’s Borah is a good example of why they matter: its +25 mm offset version is listed as compatible with the JL and Gladiator only, and AEV states it does not fit the JK. The 0 mm version fits all three. Same bolt pattern, different answer.

Load rating. Wheels carry a weight rating, and on a heavy Unlimited with a loaded roof rack, or a Gladiator hauling in the bed, a cheap wheel can be under-rated. Jeep’s manuals warn against tire and wheel sizes or load ratings other than those approved for the vehicle.

TPMS. Jeep’s JK and Gladiator manuals warn that aftermarket wheels can damage tire pressure sensors. If the light starts flashing after a wheel change, our guide to the blinking tire pressure light on a Jeep explains why.

Lug nuts, studs and torque

The JK and JL share a bolt pattern but not a lug thread. The JK uses 1/2-20 studs and a 19 mm socket. The JL and Gladiator use M14x1.50 studs and a 22 mm socket. A JK lug nut will not thread onto a JL stud properly, and forcing it will damage the stud. If you move wheels between generations, move to the correct nuts as well. Jeep’s manuals also say to use only dealer-recommended lug nuts and to clean dirt and oil off the threads before tightening.

The torque figures Jeep publishes:

• TJ: 95 ft-lb (130 N·m), per the 2006 owner’s manual.
• JK: 95 ft-lb (130 N·m) in the 2008, 2010, 2011 and 2012 manuals; 100 ft-lb (135 N·m) in the 2014 and 2017 manuals.
• JL: 130 ft-lb (176 N·m) for the road wheels. The 2021 manual lists 59 ft-lb (80 N·m) for the spare tire carrier on the swing gate, which is a different figure from the road wheels.
• Gladiator: 130 ft-lb (176 N·m), per the 2024 manual.

Jeep’s procedure is the same across generations: tighten in a star pattern until each nut has been tightened twice, using a calibrated torque wrench and a six-sided deep socket fully on the nut, then recheck the torque after 25 miles (40 km). Impact guns at tire shops can easily overshoot these numbers, which stretches studs and makes a roadside tire change much harder. A lug nut check belongs on any Wrangler maintenance checklist, especially after trail days.

Aftermarket wheels sometimes need a different seat style or a longer thread engagement than factory nuts provide. Follow the wheel maker’s lug nut specification, not the one for your old wheels.

Which wheels interchange

The JL and Gladiator are the easiest pair: same pattern, same M14x1.50 studs, same torque, and most aftermarket wheels list both. The JK and JL are the pair where people get caught out. Factory JK wheels are widely reported to bolt onto JL hubs, but the reverse is offset-dependent, and a wheel that clears a JL’s brakes and control arms may rub a JK’s. Always read the fitment line for your generation on the specific wheel, not just the bolt pattern.

Wheel spacers and adapters: what to know first

A spacer pushes the wheel outward without changing the pattern. An adapter does the same and also changes the pattern, for example letting a TJ run JK wheels. Spidertrax’s TJ-to-JK adapter is 1-1/4 inches thick per side, and its JK-to-CJ adapter is 1-3/8 inches. That is a lot of extra track width.

• Buy hub-centric. A hub-centric spacer or adapter locates on the hub’s pilot and centers the wheel on its own pilot. Lug-centric types rely on the nuts alone and are a common source of vibration.
• Match the studs. An adapter for a JL or Gladiator needs M14x1.50 studs and nuts; one for a TJ or JK typically uses 1/2-20.
• Two torque specs. The adapter nuts and the wheel nuts each get torqued to the maker’s figures, and both get rechecked after the first drive.
• Extra leverage. Moving the tire outward increases the load on ball joints, hub bearings, tie rods and the steering damper. Combined with larger tires, this is one reason worn front ends show up sooner. Our Jeep Wrangler death wobble guide covers the parts that take the strain.
• Legal and warranty points. Some states limit how far tires may stick out past the fenders, so check your state’s equipment rules before you commit.

If the only goal is a little more tire clearance on a JK or JL, a wheel with the right offset is usually a cleaner solution than a spacer. It adds one fewer joint to the wheel end.

Buying used wheels: a quick check

Used factory wheels are cheap and plentiful because so many owners swap to aftermarket sets on day one. Before you buy:

1. Confirm the generation the wheels came off. A seller’s “Jeep wheels” could be TJ 5×4.5.
2. Ask for the stamped size and offset on the back of the wheel, or check the part number with a dealer.
3. Make sure the matching lug nuts are included, or budget for a set for your generation.
4. Check for curb rash on the bead seat and any bend, especially on wheels that have been off road.
5. Decide whether you will move your TPMS sensors or buy new ones.

For winter, a second set of factory wheels with dedicated snow tires is one of the more practical uses of a used set, as covered in our Wrangler winter upgrades guide. Mount them, torque them to the figure in your own manual, and recheck after 25 miles.
