What does the Disassembly Grooves Design Means?
Dismounting grooves means the small notches which are distributed on the corner of wheel spacers. It is designed to easily dismount the spacers, improving user experience. Normally, it leaves a limited clearance between the axle plate and spacer, using a screwdriver can easily remove the spacers, simple and efficient. If there is no such groove, the spacer will snug the vehicle hub, by forces effect, it can be difficult to dismount. Even worse, you may destroy the spacers or axle hub. Furthermore, the grooves can act as an air collecting funnel, which is effectively increasing airflow, enhancing the heat dissipation effect.
