Hi I’m Tony, I have a 2015 Dyna street bob

[TonyTone]

Hello all, so I have a 2015 Dyna street bob. I would like to change the rim size to 21 3.5 front and 18 or 16 5.5 in rear. I don’t know anything about tire sizes, bearings, rotors, abs, No abs. So what I’m asking is what would be a good size tire? What size bearings and rotors do I need. And basically what else do I need for a rim change?

Welcome from Spokane Washington.
I have no information to help you but I would confirm the bike frame and fenders have the clearance for the changes before buying anything.
