If you want to slightly enhance the performance, aesthetics, and handling of your car, 10mm spacers are often a topic of interest. Wheel spacers create additional clearance between the wheels and vehicle assembly hubs, providing a more aggressive stance, improved stability, and even better cornering performance. Many car enthusiasts wonder, “Are 10mm wheel spacers safe to use?” The answer is a resounding yes—when installed and used properly.

Normally, 10mm spacers are too thin to come with pressed-in wheel bolts. So, for a proper installation, you need longer wheel bolts for 10mm spacers. This leads to another question: What size bolts do I need for 10mm spacers? This blog delves into the benefits, safety considerations, and best practices to help you make an informed decision.

How Long Wheel Bolts Do I Need for 10mm Spacers?

Simply, 10mm spacers occupy about 10mm bolt thread which stops the OEM wheel bolts from engaging the full thread. On this basis, if the OEM wheel bolt length is 27mm and you get a 10mm wheel spacer installed, it is recommended to use 37mm bolts (stock bolt length + spacer thickness = required wheel bolt length). If you get aftermarket wheels installed, it is better to get new wheel bolts that are a little longer than those.

What Sizes 10mm Spacers Are Best?

The most popular 10mm spacers sizes are 5×112 10mm spacers, 5×120 10mm spacers, 10mm spacers 5×114.3, and 4×108 10mm spacers. Wheel lug pattern is one of the keys to identifying wheel dimensions. When installing wheel spacers you have to confirm the correct lug pattern. The 10mm spacer must have the correct bolt pattern to match your vehicle’s hub and wheel. Incorrect fitment can lead to improper load distribution and potential wheel detachment.
