Do I need new lug nuts for aftermarket wheels?

In most cases, yes. When upgrading to aftermarket wheels, new lug nuts are typically required to ensure a safe and proper fit. Here is what you need to know.

Why can't I use my factory lug nuts?

Factory lug nuts are designed specifically for your factory wheels and may not be compatible with aftermarket wheels. The most common reason is that aftermarket wheels often have a different seat type than factory wheels. The seat is the area where the lug nut makes contact with the wheel, and using the wrong seat type can result in improper seating, which can cause the wheel to be unsafe or come loose while driving.

What are the different lug nut seat types?

There are a few common lug nut seat types to be aware of:

• Conical or tapered seat: The most common type, featuring a cone shaped taper that seats into a matching tapered hole in the wheel
• Ball or radius seat: Features a rounded seat that matches a rounded hole in the wheel, common on many Honda and Acura vehicles
• Flat seat: Features a flat washer style seat, common on many European vehicles

Using the wrong seat type can prevent the lug nut from seating correctly, which can be dangerous. Always make sure your lug nuts match the seat type of your new wheels.

What about lug bolts?

Some vehicles, particularly European makes, use lug bolts instead of lug nuts. Lug bolts thread directly into the hub of the vehicle rather than onto a stud. If your vehicle uses lug bolts, it is important to make sure any aftermarket lug bolts are compatible with both your vehicle and your new wheels.

Tips for lug nut installation

Regardless of which lug nuts you use, always follow these guidelines during installation:

• Always hand tighten lug nuts first in a star pattern to ensure proper centering
• Never use power tools or impact wrenches as they can over torque the bolts or strip the threads
• Torque lug nuts to your vehicle's manufacturer recommended specifications using a calibrated torque wrench
• Recheck your lug nut torque after the first 50 to 100 miles of driving
