Does that matter if i'd use a stans rim strip?
The companies selling the tyres and rims would say "definitely yes" and tell you that you need TLR rims and TLR tyres.
In my experience, as long as you understand how rim+tyre interface works, and you understand how tubeless tyres work, you can easily judge whether a given setup will be workable.
Example: TLR rims have larger diameter to account for the better seal. However, you're wrapping tape on the rim anyway - there's nothing stopping you from adding two more wraps to build up the thickness.
Even if you're a wizard with tire levers and have orangutang forearms it can be a struggle
Compared to larger-format motorcycle tyres, anything on bikes is comparatively quite pliable. In fact, the main risk I've witnessed is the tyre being too soft to properly form the initial seal. The initial seal is half the battle - if the tyre has intact bead, and the rim has intact lip, it should all eventually seal and close up. This might take
days. Afterwards, it's all a matter of keeping the pressure on.
Tubeless setups get progressively easier to maintain pressure the higher pressure you have, because the pressure doesn't just hold the vehicle up, it also pushes the tyre to the rim. Bicycle tyres don't normally run rimlocks, and so are susceptible to spinning on the rim under heavy breaking. In my experience, you can progressively lower the pressure with time, after the tyre slowly conforms to the shape of the rim.
TPU tubes are lightweight and pack super small but have horrible puncture resistance. I would consider them only as a backup for if/when your tubeless tyre loses seal when out. That's the main reason why i recommend going TL to everyone - the worst case scenario is just putting the tube in. And as long as you don't put absurd amounts of sealant, you can just wipe the minuscule amount left with a tissue.
For reference, my 150/80-18" tyre on a 4" rim used 40ml of sealant, and that was likely twice as much as required. I don't believe in using the sealant as a preventative measure for punctures, and thus don't see the reason to fill more than absolutely necessary to seat the bead on.
So, practically, if your tyres are in a reasonably good condition[1], have intact beads and your rims are straight, you should be able to just apply tape and a
very small amount (or none) of sealant and get them to fit. In fact, I'd start with just soapy water instead of sealant to get an idea of how it's going to sit if you're unsure[2]. At that stage, you're almost guaranteed to have a leak
after the tyre gets on the rim. That's normal and expected, and can come from (typically) one of two places - either the tape or the bead. Tape leaks will manifest on spoke nipples, bead leaks obviously on the bead. Pump the tyre to maximum nominal pressure - which can be a lot for a bike tyre, again, which helps a lot. If you can get it to hold air for ~15 minutes, go for a ride. If you can't (deflates in a couple minutes), let it sit under pressure for an hour or so, adding air as needed. If it deflates almost instantly after correctly seating on the bead, that's where I'd add a small amount of sealant and then try to keep it at pressure as long as possible. Ideally, with more time and more sealant penetration, you should be able to increase the time (decrease the leak rate) eventually to almost perfect 0. Again, this might take days and a couple rides. Last tyre we did, an experimental size mismatch on an experimentally laced rim, took about a week to finally start holding pressure. AFAIK, it's now losing virtually no air - while the owner was ready to call it hopeless and put a tube back in, against my suggestion, on day 1.
My personal bike's (not motorcycle) front tyre is a cheap 2.4" Kenda, and for the first couple days, i could get it to burp sealant with bare hand pressure even at 3.0+ bar pressure. Now it can sit at 1.0, low enough where i can press the tyre down to the rim almost, and I wouldn't be able to do that.
I wasn't intending to write this post as a guide but here we are I guess
[1] IME it's best to use a brand new tyre.
[2] This means that if at any point you decide my advice is crap, you really have no mess to clean up.
