Frame is supposed to be able to fit 28c tires, I switched from 25c to 28c tires and I'm pretty sure I'm getting frame rub while riding.
Chain tension is good and I pulled the wheel back as far as I could, but the chain is only a few weeks old at this point so I still have a lot of room in the dropouts.
Do I need a longer chain or do these tires just run too big for 28c?

There is no clearence mate
you can try a few different brands of the same size but this is very tight indeed. Wouldn’t ride it.
Do you still have room in the drop out, to move the wheel back? if so, yes you need a longer chain.
This isn’t going to work out. try with an extra pair of links in the chain.

That tire will likely even rub after a few rides. A new tire grows slightly after first usage.
Stick with 25mm or get a new bike.
a longer chain? is this a fixie? if you have room on the dropout, lengthen your chain.
Don´t. Tires stretch and get bigger with time.

Either one, but this setup isn’t gonna work.
If you get wheels with a wider bed, it *might* work.
That’s going to rub, wheels and tires move/grow a bit when riding or even when the temperatures change a lot.
a playing card is sending you over the handlebars
You can likely clear it with a longer chain. The goal is pinky or more or you’ll sandpaper the frame on a rainy day. Tires pick up grit and fling it around.

Do some big skids or add a link into your chain.
You’re going to need a feeler gauge to inflate your tire. (It’s too close).
Nope
Along with what everyone else said, your tires will pick up small pieces of debris that will get jammed inbetween the tire and frame, and will scratch and mare your frame.
You spelled non-existent wrong.
You forgot to post a photo of the dropout with the axle in it. That’s where your clearance went.
Add a set of links to your chain. If that makes the chain too long and you can’t safely seat in the track fork ends, install a half-link instead.
Nonexistent
Where do you think the air goes once you’re on your bike?
A good rule of thumb to check clearance, you should be able to slide a 4mm hex between the tire and the frame.
no bueno
