If you’re looking to boost performance, improve looks, and sharpen handling, 10mm wheel spacers are a popular choice. By creating extra space between your wheels and hubs, spacers give your car a more aggressive stance, better stability, and sharper cornering. But one question comes up often: Are 10mm wheel spacers safe? The answer is yes—when installed correctly.
Since 10mm spacers are relatively thin, they usually don’t come with built-in lug bolts. That means you’ll need longer bolts to safely secure your wheels. So, what size bolts do you need? This guide covers key benefits, safety tips, and best practices to help you make a smart decision.
What Length Lug Bolts Do I Need for 10mm Spacers?
When you add a 10mm spacer, your factory lug bolts won’t have enough thread to grip properly. To fix this, your new bolt length should equal your factory bolt’s length plus the spacer’s thickness.
For example:
If your stock bolts are 27mm, go with 37mm bolts after adding a 10mm spacer.
If you’re running aftermarket wheels, it’s wise to get bolts slightly longer than the calculated size for a secure fit.
Which 10mm Spacer Sizes Are the Right Fit?
The most common bolt patterns for 10mm spacers in the market include:
5×114.3 (Honda, Nissan, Toyota, and others)
5×120 (BMW, some GM models)
5×112 (Audi, Volkswagen, Mercedes-Benz)
Matching the spacer’s bolt pattern to your vehicle is critical. An incorrect fit can cause uneven load distribution, vibrations, or even wheel failure.
