You used epoxy to glue them? Some epoxies have issues adhering to PETG, best solution is using sikaflex or something like it, its a PU based glue/sealant. It handles like a silicone kindoff. @Andy87 used that and since ive recommended it to many others which had good results. There is also the 3M vhb tape option, can be bought on amazon.
Your solution looks pretty cool though well done! sheet metal master
Sikaflex definitely works perfectly. If on hand, using some primer first, does help for some extra strength. I could basically lift the board on the wings without them getting off. Still easy to remove using a razor blade and cut between the deck and the blades.
Using epoxy or similar stiff bonds are a bad choice. Due to the flex in the deck, they will break off over time.
Besides a a large amount of vibrations on asphalt these tires seem pretty good they don’t wobble. When riding on anything that’s not asphalt like dirt or grass or something else you don’t notice the vibrations from the knobbies.
I have the softest bushings available on the front and rear of these trucks and they feel great to me. I have to find a way to get more foot real estate on this board because right now if I don’t have a super narrow stance my feet hit the wheels.
Also I packed the gear drives with a shit ton of grease and they sound great with these tires
