Sellers love the phrase "should fit your car," but it's the most expensive phrase in the wheel business. A wheel either fits by the numbers, or it doesn't. "Should" is what's left when the seller hasn't checked and hopes you won't either. The bargain that’s "close enough" usually ends up rubbing, shaking, or not clearing the brake. Now, you own a problem you can’t return because you were warned in the vaguest way possible.
The four numbers that end the argument are pattern, bore, offset, and seat type. You can read pattern and bore off the wheel itself or measure them. Offset is stamped on the back. Seat type is the shape of the contact face that the nut meets. A cone-seat nut on a ball-seat wheel looks tight but isn't. That's a different failure than a wrong pattern, but both trace back to skipping the check. The wheel stamped its own truth; the listing just hoped you’d ignore it.
Condition is the other half. A barrel bent from a pothole will balance forever and shake forever because balancing can't unbend metal. I can live with curb rash, but I can’t live with a wobble. The difference is visible if you spin the wheel and actually look at it instead of judging it from a thumbnail photo.
Do the math before the money changes hands, because used wheels are the best value. Skip this step, and you’ve bought a paperweight with a nice finish.
