How to Find Your Car's Bolt Pattern (Without Guessing)

Your bolt pattern is the first thing you need before buying wheels — and the easiest thing to get wrong. Here are three ways to nail it down.

What a bolt pattern actually is

It's two numbers: the lug count and the diameter of the circle those lugs sit on, in millimeters (or inches). Example: 5x114.3 is five lugs on a 114.3mm circle. 6x139.7 is six lugs on a 139.7mm circle — common on trucks.

Method 1: Look it up by year/make/model

The fastest route is a bolt-pattern lookup using your exact year, make, model, and trim. Trim matters — some models changed patterns between generations or trims, so the name alone isn't enough.

Method 2: Count and measure

• Even lug counts (4, 6, 8): measure center-to-center across two directly opposite lugs.
• Odd lug counts (5): measure from the back of one lug to the center of the lug two over (you can't go straight across with five). Then convert with a 5-lug chart.

Method 3: Check the door jamb / owner's docs

Some vehicles list wheel/tire info on the door placard or in the manual. It won't always show bolt pattern directly, but it confirms OEM wheel size and offset, which helps cross-reference.

The mistakes that cost a return

• Assuming two close patterns (like 5x114.3 vs 5x120) are "close enough" — they are not interchangeable.
• Ignoring trim differences.
• Matching bolt pattern but forgetting hub bore, offset, and clearance.

Once fitment checks out, the only question left is the look — and that's where seeing the wheels on your actual car beats imagining it. Keep reading: what 18x8 +35 means.
