How to Choose The Right Wheel Spacer
Choosing the compatible wheel spacers is essential for a safe and comfortable driving experience. To achieve that, you may need to confirm the following 6 parameters of your wheel sets.
1. Bolt Pattern
Bolt pattern refers to the number of bolt holes on the wheel hub and the diameter of the circle on which these holes are distributed, such as 4×100, 5×114.3, 6×139.7.
It must exactly match the layout of the wheel hub (axle head). If the bolt pattern does not match, the wheel cannot be installed, and forced installation may pose safety risks.
For wheel hub modifications that require adapting to a different bolt pattern (e.g., converting from 4-lug to 5-lug, or from 5×120 to 5×114.3), conversion spacers must be used. These spacers are also known as adapter flanges.
You can find the information by checking the vehicle manual or the back of the wheel hub. You can also measure it by following this video tutorial: How to Find your Wheel Bolt Pattern
2. Center Bore
The center bore is the hole at the center of the wheel hub that aligns with the vehicle’s axle for precise centering.
When using hub-centric spacers, the center bore must match the axle exactly; otherwise, it may cause wheel misalignment, vibration, and loose lug nuts.
3. Thread Pitch
Thread pitch refers to the diameter and spacing of your lug bolts — for example, M12x1.25 or M14x1.5. It’s crucial that the spacer’s studs (or the nuts you use) match your vehicle’s original thread pitch exactly.
Using the wrong thread pitch can strip the threads, prevent proper tightening, or cause the nuts to come loose. Always check your car manual or remove a lug bolt and look at its markings.
4. Thickness
Thickness determines how far the wheels are pushed outward from the hub. Choosing the right thickness can improve wheel clearance, achieve a flush stance, or help fit aftermarket brake kits.
Too thin, and the spacer may not resolve clearance issues. Too thick, and the wheels may stick out past the fenders or rub against suspension parts. Common sizes are 10mm, 15mm, 20mm, and 25mm.
For small adjustments (e.g., 10–15mm), a slip-on spacer is usually enough. For thicker setups (20mm+), use a bolt-on spacer for better strength and safety.
5. Hub Centric vs. Lug Centric
A hub-centric spacer centers the wheel using the axle hub. This ensures perfect alignment and is usually preferred for OEM wheels and high-speed driving. Lug-centric spacers center the wheel using the lug bolts — suitable for some aftermarket wheels with oversized center bores.
Hub-centric wheel spacers have a cylindrical protrusion in the center, while Lug Centric ones feature a smooth hole. You can check the comparison images we prepared to quickly understand their differences.
If your wheels are lug-centric, it’s a good idea to use hub rings to improve alignment. Whenever possible, choose hub-centric spacers for better stability and balance.
6. Slip-on vs. Bolt-on
Slip-on spacers slide over the existing studs and are held in place by the wheel and lug nuts. They’re simple and work well for thinner sizes, but only if you have enough thread engagement.
Bolt-on spacers, on the other hand, bolt directly to the hub and come with their own studs to mount the wheel. These are recommended for thicker spacers (usually 20mm and above), or when converting bolt patterns.
