Wheel bolt pattern (also called PCD — Pitch Circle Diameter, or lug pattern) defines two things: the number of bolts and the diameter of the imaginary circle they sit on. Both numbers must match exactly between the wheel and your hub. A 5×114.3 and a 5×120 pattern look nearly identical but differ by 5.7mm — just enough to thread on a few turns before the studs fail under load.
Quick answer
Your bolt pattern is in the owner’s manual under “Wheels” or “Specifications.” Read as: bolt count × PCD in millimeters — for example, 5×114.3 means 5 bolts on a 114.3mm diameter circle. The center bore diameter, wheel offset (ET), and thread size also matter for a complete fitment. Pattern alone is not enough.
Specifications
| Parameter | Common Values |
|---|---|
| Most common patterns (passenger) | 5×114.3, 5×120, 5×112, 4×100, 5×100 |
| Most common patterns (truck) | 6×135, 6×139.7, 8×165.1, 8×170 |
| Thread — Japanese / Korean | M12×1.5 |
| Thread — American trucks | M14×1.5 |
| Thread — European (most) | M14×1.5 or M14×1.25 |
| Center bore range (passenger) | 54.1mm – 73.1mm |
| Offset (ET) typical — passenger | ET25 – ET55 |
| Offset (ET) typical — truck | ET0 – ET30 |
How to find your spec
- Owner’s manual — look under “Wheels,” “Tires,” or “Technical Specifications.” Lists bolt pattern, center bore, and approved offset range.
- VIN lookup via wheel retailers — Tire Rack, Discount Tire, and Wheel Fitment Guide all offer VIN-based lookup that returns confirmed bolt pattern, center bore, and offset range for your exact vehicle and trim. This accounts for differences between trim levels that share a model name but use different wheel sizes.
- Measuring directly — for 4-bolt wheels: measure diagonally between the centers of two opposite bolts. For 5-bolt: measure from the center of one bolt hole to the outer edge of the bolt hole directly across, then multiply by 1.051 to get PCD.
- Center bore measurement — use calipers on the large central hole of your current wheel. A replacement wheel must have a center bore equal to or larger than your hub diameter. If larger, hub-centric rings bridge the gap.
- Stud vs. bolt fitment — most Japanese and American vehicles use studs (threaded rods on the hub) with lug nuts. Most European vehicles use hub bolts (the bolt is part of the wheel and threads into the hub). These systems are not interchangeable without hub modification — confirm which your vehicle uses before ordering wheels.
How to check
- Confirm bolt pattern and center bore before purchasing wheels — verify by VIN lookup, not by model name alone. Trim levels within the same model year can use different specs.
- Measure center bore on your current wheel and compare to your hub diameter. Order hub-centric rings if the replacement wheel’s center bore is larger than your hub.
- Check offset (ET) — confirm the replacement wheel’s ET falls within your owner’s manual’s approved range. Incorrect offset pushes the tire into the fender or suspension, or stresses the hub bearing unevenly.
- Dry-fit before final torque — mount the wheel and thread all fasteners by hand. If the wheel doesn’t sit completely flush against the hub face, stop and investigate before applying any torque.
- Torque to your vehicle’s lug nut spec in a star pattern. Re-torque after 50 miles.
What goes wrong
- Confusing 5×114.3 and 5×120 — the fasteners thread on 2–3 turns before binding. The wheel feels seated. Under driving load — acceleration, braking, cornering — the studs shear. This is a catastrophic and dangerous failure, not a nuisance problem.
- Skipping hub-centric rings — a wheel centered only by its lug nuts (lug-centric fit) vibrates at speed and places lateral load on the fasteners instead of the hub flange. Hub-centric rings cost $5–$15 and eliminate both issues.
- Wrong offset — too much positive offset pushes the wheel inward, causing tire rub on the inner fender or upper control arm under full compression. Too much negative offset pushes the wheel outward, stresses the hub bearing laterally, and may be illegal in some states due to wheel well protrusion laws.
- Shopping by model name instead of VIN — a 2019 Ford F-150 can have a 6×135 bolt pattern on one trim and the same 6×135 on another, but different center bore and offset requirements. Always verify by VIN, not just model year and name.
