Jeep Wrangler Bolt Pattern, Wheel & Tire Sizes
TL;DR
YJ and TJ Wranglers use a 5x114.3 mm bolt pattern; JK and JL Wranglers switched to 5x127 mm. Centre bore is roughly 71.5 mm on all generations, and stock tire sizes range from 15-inch off-road rubber on early models up to 20-inch wheels on late JL trims.
Bolt pattern changed twice across Wrangler history
The Wrangler's 5-lug bolt pattern is not the same across every generation. Early Wranglers (YJ and TJ) share a 5x114.3 mm (5x4.5 in) pattern. When Jeep redesigned the platform for the JK in 2007, the pattern moved to 5x127 mm (5x5 in), and that carried over to the current JL generation. A small number of 1991-1995 YJ trims are reported by some parts catalogues to have used an optional 5x5.5 in pattern; this could not be corroborated across multiple sources, so treat it as something to verify on your own vehicle rather than a confirmed fact.
Centre bore and stud thread
Multiple wheel-fitment databases list the centre bore for YJ, TJ, JK and JL Wranglers in a narrow 71.5-71.6 mm range - sources differ by a fraction of a millimetre, which is common rounding variance rather than a real generational change. Stud thread is 1/2 in-20 UNF on YJ and TJ models. On JK and JL models most trims use M14 x 1.5 studs, though some earlier JK trims are documented with 1/2 in-20 UNF instead - the two thread types are not interchangeable, so confirm which one your Wrangler has before ordering lug nuts or spacers.
Stock wheel and tire sizes
Wheel diameter grew over time: 15-inch steel wheels on early YJ/TJ trims, 16-18 inch wheels through the JK years, and 17-20 inch wheels on the JL, including 20-inch wheels on high-trim and performance JL variants. Tire sizes follow the same trend, from around 215/75R15 on early models up to LT285/70R17 and 275/55R20 on later Rubicon, 392 and high-trim JL builds.
Always confirm on your own vehicle
Because trim-level wheel and tire packages vary within a single generation (Sport, Sahara, Rubicon, and special editions all differ), the authoritative source for your exact Wrangler is always your own vehicle: check the driver's door jamb placard, the owner's manual, the size markings stamped into your current wheels and tires, and the manufacturer's towing/payload guide if you plan to change wheel or tire size.
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|

Frequently asked questions
Did the Jeep Wrangler always use the same bolt pattern?
No. Early Wranglers (YJ 1987-1995 and TJ 1997-2006) use a 5x114.3 mm bolt pattern, while the JK (2007-2018) and JL (2018-present) generations use 5x127 mm. Wheels built for one pattern will not bolt onto a hub with the other pattern.
Is the centre bore the same on every Wrangler generation?
Reference databases list a very similar centre bore, around 71.5 to 71.6 mm, across YJ, TJ, JK and JL models. Because aftermarket wheels are often cast with a larger bore and fitted with hub-centric rings, always check the bore stamped on the wheel itself against your hub rather than assuming a figure.
What stud thread does my Wrangler use for lug nuts?
YJ and TJ models use 1/2 in-20 UNF studs. JK and JL models mostly use M14 x 1.5 studs, though some earlier JK trims are documented with 1/2 in-20 UNF instead. The two are not interchangeable, so match lug nuts to the thread on your own studs, which you can check at a tire shop or against your owner's manual.
Where can I find the exact wheel and tire size for my specific Wrangler?
The tire size and load rating are printed on the tire sidewall itself and on the driver's door jamb placard, which also lists the recommended wheel size and cold tire pressure for your exact trim. The owner's manual and, for towing-related limits, the manufacturer's towing guide are the other authoritative sources.
