Jeep Wrangler Bolt Pattern Specifications
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Bolt pattern | 5 x 127 mm | 5 x 5 in; five lugs |
| Wheel-stud thread | 1/2-20 | 2012 JK factory row |
| Lug-nut seat | 60° cone | Match the wheel seat |
| Wheel-nut torque range | 92–132 lb-ft | 125–180 N·m |
Bolt circle alone cannot establish wheel fit. Confirm center-bore engagement, backspacing/offset, brake and steering clearance, load rating and the wheel maker's approved 60-degree seat before mounting. Do not lubricate the stud or cone unless the exact wheel procedure says to revise the dry-thread torque.
What the JK wheel specification tells you
The 2012 JK's five studs lie on a 127-mm circle, usually written 5 x 127 or 5 x 5 in. The service row further identifies 1/2-20 threads and a 60-degree cone nut. Those details matter because a nut with the wrong thread or seat can appear to tighten while failing to clamp the wheel correctly.
Jeep publishes a 125–180-N·m (92–132-lb-ft) range for the covered hardware. Use the exact wheel and owner/service instructions to select the intended value within that factory range, particularly with approved accessory wheels. Start every nut by hand and tighten across the five-lug pattern in stages.
Why a matching bolt circle is not enough
A 5 x 127 wheel can still interfere with the brake caliper, steering linkage or suspension, or place the tire too far inward or outward. Verify center bore, backspacing/offset, width, diameter, load rating, tire envelope and cone-seat compatibility before purchase.
Clean the hub and wheel mounting faces so corrosion cannot hold the wheel off-center. Keep the factory dry threads free of oil and anti-seize unless the exact procedure provides a revised lubricated value. Recheck seating after service as directed for the installed wheel and investigate any looseness rather than repeatedly adding torque.
