I’ve successfully stopped my wheel from going side to side as much as I can but now it’s going up and down 😭.
How the hell do I fix this.

You basically keep the horizontal tension the same but now look for the vertical tension. Same procedure.
you can redish the wheel or laterally true it. otherwise leave it
I’d worry more about the movement of the brake disc.
Your rotor needs straightening a little, also it’s either a cheap one or is a tiny bit offset vertically on the mounting holes. You could try loosening the bolts and tightening them again in the correct star shaped order. Your rim being out of radial true is a completely separate issue. If spoke tension is reasonably even and ok I’d probably leave it to be honest. It’s not badly out, matters less with a disc wheel where a perfectly round rim brake surface is needed and you’ll probably not notice it when riding as the tyre will absorb any small irregularity.
The part that dipps down at the top would need to be loosened so it wouldn’t dip.
If you ride it and don’t notice you can probably leave the wheel alone.
The brake rotor can be bent easily with a rotor bending tool. Sometime they are attached to pedal wrenches. It’s just a rench ish shaped tool with a slit in it about the width of a rotor. Bend it in place still mounted.
Looks like something happened to the whole wheelset (rim, hub, rotor). The rotor is connected to the hub. The rim is connected to the hub by the spokes. If you true the spokes to straighten the rim, it won’t fix a bent rotor.
It’s your brake rotor that’s out of whack and rubbing on your pads. You can do the same thing with the zip tie for your rotor and you bend it back into alignment. You won’t get it perfectly straight but you should be able to get it to where it’s not rubbing anymore or barely rubbing and if it is still rubbing then reset your piston, it’ll give you a little more wiggle room. You can just use a pair of pliers to bend it. There’s rotor tools made for that but pliers will work just fine. Just be careful when doing it, bend it a little bit at a time. It doesn’t take much to bend the rotor and you don’t want to overdo it then have to bend it back the other way, it’ll weaken the integrity of the rotor. Check YouTube, there’s all sorts of videos on how to realign your rotor
If spoke tension is relatively even that’s a perfectly acceptable amount of lateral and radial run out. Leave it.
Next time better to use a tork wrench instead of full power on the bolts
bend it back – adjustable wrench
You just need a beat
Vertical or radial true when you have a flatspot can get complicated. A flat spot about that big is removable, but you will end up redoing the lateral true at the same time.
Radial trueness is also a good indicator of how much life is left in the rim. A rim with 3 or 4 flat spots and different eccentricities is often up for replacement. 1 like this is just regular impact damage.
Is the disc striking the top of the calliper? It looks like the disc protrudes beyond the top of the friction material on the pads. It’d be worth sticking a washer between the calliper and brake mount on both bolts.
You only tightened spokes if I am guessing. You may have caused mis-balanced tension in the wheel. I tap spoke before tweaks. If the opposite side spoke to either side of the one I am adjusting have higher pitch, I loosen those 2 instead of tightening the one between to get the rim toward desired direction.
Check the wheel bearings. Or the rotor or hub is machined or drilled off spec. Which may not matter too much rolling if not dragging really. Ain’t a Ferarri.
I would ride that wheel. Looks fine.
Tire looks like it’s not beaded right, though.
This is one of those situations (for me, since I’m new to biking) where a day of working some side gig to earn enough to pay a shop to fix the bike is far easier and less stressful than the 2 hours I’d spend fucking the rim up followed by the hour it would take me to realize I just fucked my rim up.
That’s why I still use rim brakes sorry folks i just don’t want to handle that kind of bullschit
Bend it before you send it. Find the pint where it touches and give it a small finger bend in the opposite direction. Repeat until it’s centered.
Then send it.
WTF mounted that tire????
Personally, I would take it to LBS.
