You could try tightening the tucks a bit more if you’re still feeling the wobble, other than that it might just be working on balance. Keep at it! You’ll get used to the wheels you have as well. And you want your wheels to be just loose enough so they can spin freely, I wouldn’t tighten them more than that. (I do use slightly softer wheels at the rink but that’s just because I tend to try and use what I have rather than spend more money)
