Take them to a tame tyre dealer. You could remove them with levers but breaking the beads is a real pain. Also chances are you will damage the alloy.
I have my own Chinese unbranded tyre machine which I bought brand new off my tame tool dealer for £40. The only reason I bought it is even in second hand condition it is worth £40 any day of the week.
easiest way is to pay someone else to do it. it is possible with tyre levers doing it by hand but its easy to damage the rim unless you are careful. also the lower the profile of the tyres,the harder it gets to remove them
the term "breaking the bead" - that is pulling the bead over the edge of the rim, right?
could (and i really dont know, else i wouldnt be asking) i do somthing like cut arround the side wall, push the bead into the center, and then cut through it with bolt crops?
Breaking the bead is getting the beads off the rim into the centre well, takes a bit of force. Google 'bead breaker' and you will see the sort of tools available or other home methods to break the bead.
If you have access to a large fly press you can use it to break the bead, it's what I use. Once the bead is broken I use a angle grinder to cut through the wires on the bead then it's a doddle to get the tyre off.
If they are rims from an old Series Landrover with tubes then they won't have a bead ridge and they are doable at home, even ones with beads are too as the side walls are quite deep and the rims have a deep well.
You can break the bead with a Hi-Lift jack, stick the wheel under something heavy that you can jack against(like a Landrover) and put the jack as close to the rim as you can. Once you have broken the bead(even ones without a bead will still need to be moved) then it's just a matter of compressing onside of the tyre so the bead sits in the well and then use a tyre lever at 180 degrees to ease it over the rim. If they are LWB rims then you need to do this from the back face.
I changed lots of Landrover tyres but I have a tyre changer and personally once you've done one by hand you'll be loading the others in the car and giving someone £10-15 to do the rest. It will take them 20mins to do all of them tops
I have a friend who does 900x16 at home manually, I've told hime loads of times he has to stop doing it, he says your arms are like Popeye afterwards
If you want to use the alloys again then just take them somewhere. Even with a tyre changer some of those older Landrover alloys need the bead broken in 2-3 places on each side to free them up. Classic Range Rover alloys can be a nightmare(3 spoke ones), I've had the rims flexing before the bead breaks.
If you go the diy route and do manage to break the bead, a few 4" lengths of garden hose slit lengthways can be popped over the rim edge and used to protect it while you're levering.
I fully understand the time involved in dropping your partner at work and collecting but why not drop them at work and take the wheels with you, drop the wheels off and pick them up on the way way to collect you partner. It will 100% be a better day than the time you will waste getting those tyres off safely
Take the rim to an independent tyre dealer... they will remove, dispose of and fit you new ones....drop them off and get the other half to collect them...
one job its worth paying for imo...find a back street cash in hand type geezer rather than a high street chain , drop em in and ask can he pop them off when he gets time and you will be back later with some cash , weekdays easier than a busy sat morning
Land Rover sized tyres are difficult to break the bead with a manual machine. I've even used a Hi-Lift under the towbar of my Range Rover and it lifted the vehicle off the ground without moving the bead a mm !
Also council regard Land Rover sized as commercial so don't allow free disposal.
IMO if you want to reused the rims get a dealer to remove them.
Never done it myself, but as the op says they are waste tyres, can't you just cut the sidewalls with a sharp implement all the way round , thus removing the bulk of the tire.
If you have done that , do you still need to then break the bead ? It will the remement of the side wall just be able to be removed by hand ?
