Do I need Spacers Between Boardnamics Abec Pulleys and Zoobomb 111 wheels?

General Discussion

I should add, this is my first time posting and my first time putting pulleys on street wheels. Basically, I’m wondering if I need to put spacers between the press fit Abec Pulleys and the wheels. I have already installed spacers between the wheel bearings.

Thank you in advance.

I do none of that. I run the nut till it slightly slows, back it off, and then leave it. I got some 10mm dia spacers, and intend to someday be allowed to sock down all nuts. I understand the advantage, but this works fine too.
