You need to remove the circlips. You can do this without Circlip pliers but you will most likely damage the clip rendering it useless.
If I were you, I would buy some circlip pliers and safely remove the clips.
When I was frustrated, I filed down a set of long nose pliers into somewhat circlip pliers that worked well for all of 2 minutes lol
Go down to your local auto/hardware store and buy a set of circlip pliers, and if they have a bulk multipack of circlips buy them too. Get some spares you will need them.
You can assemble your wheel back without circlips but you will most likely have problems in future, so do it right the first time
