Tuner Style Lug Nuts

Lug nuts and lug bolts seem to be tiny things that are not that crucial to consider as long as everything works fine. Think of it the other way: these tiny things withstand high impact and are constantly under extremely large forces. Fail of one of these guys will lead to serious wheel and suspension damages, and that’s the best outcome. That is why it is crucial that you consider the technical basics of the wheel lugs whenever you deal with them.

So, what are the tuner lug nuts? Tuner lug nuts are designed for custom wheels, that normally feature small diameter mounting holes. Hence the name, tuner lugs. Many aftermarket wheels are designed for extremely small diameter lug nuts usually known as tuner lugs.

Tuner style lug nuts: Specs and Construction

Originally, tuner lug nuts featured open center, which allowed accepting a solid hex-shaped key to install and remove them. Today you will hardly find any of these on the market, as the construction has changed since then. The reason for the change is too open construction that allows moisture and dirt get into the tread and studs. Further, this leads to tread damage, bolt loosening and corrosion. Moisture along with the air and particles minimized the service of the wheels and tuner lug nuts, and caused serious safety hazards.

So today, in order not to compromise on safety and use the wheels and lugs as long as possible, tuner style lugs have been replaced with spline drive lug nuts.

I like my aftermarket lug nuts, yet I want to point out, that they are NOT tuner lug nuts. Well, some people call them tuner lugs, yet from technical side they are not right. Tuner lugs are something I'd never put on the vehicle that I plan on driving lol. Like the text says, they are not safe enough. Yet, aftermarket lugs are cool, just need to pick the right size.
