@Lola, I agree with @Bungus about this. I believe you are kinda' overthinking this whole business with the magnets and VHB tape. Now that you basically have what you need see how it all works for you and then later if there should be an issue you can always go back and make an adjustment or try something different. I've tried several types of 3M VHB tape and although they have slightly different properties regarding adhesion and mounting strength, they all work for holding a dash cam pretty well. Usually, VHB tape is meant for holding things that are far heavier than a little camera like a Mobius. It's been more or less the same with the different neodymium magnets I've used.
BTW, VHB stands for Very High Bond in case you haven't come across that term yet in the 3M literature.
The thing with balancing your tires is really a whole other kettle of fish but you should get than done anyway.
I just remembered I have some of these lying around:

They are meant for holding ID badges in place, but are useful for other things. I'm planning to fit 2 Mobius as side cams, and I think these will do the job nicely.
The plain metal plate has adhesive foam on the back, the magnet plate doesn't. The two magnets are opposing polarities. So you could use two of the magnet plates against each other for a really strong grip, but even when used normally (magnet plate against plain plate) the grip is very strong. It's easiest to slide or roll the attached item off rather than pull it.

The magnets are about 9mm by 2mm. They sit in slight recesses on the plate. They may be glued in (I can't actually see any glue) or perhaps fixed by applying with enormous pressure? In any case none have fallen out.

The magnet plates have nothing on the reverse, you must stick them on using a product of your choice.
The plain metal plates have double-sided sticky foam tape about 1mm thick on the back.
I use them for the intended purpose (holding an ID card.) I've also stuck a magnet plate on my van's dash using 3M VHB tape. I slap my ID on that when I don't need it, or sometimes hang keys off it.
And I've put magnet plates on some of my home's cordless phones, so I can plonk them on the fridge or a filing cabinet or whatever. (Again using VHB.)
My plans for the Mobius cameras is on hold. I thought there was a brilliant place for them, but the side mirrors would have blocked a lot of their view.
sounds like you're having a lot of fun to me. I forgot to say thanks for telling me about those name tags, it's given me some ideas also
