2.8” Tire Removal
I have a Cannondale Cujo 2 with stock WTB rims and 2.8” tires. I’m upgrading the tires to tubeless but cannot get the original tires off the rim.
If I roll the tire, with a lot of force, I can see a space between the rim and bead but am unable to get a tire lever in the space.
Any tips or is there a special tool for this size tire? I’ve changed many tires on road and other bikes and never had an issue removing tires before, this is my first time working on a mid fat tire.

Do you have the tube valve core removed and the beads on both sides of the tire fully broken from their seat on the rim?
2.8" is getting wide enough you may have to stand on the tire to get the bead to unseat. With a properly supported rim, of course.
Once that is done, it should be easier to get one side of the bead into the drop center of the rim to allow you to get the opposite side of the bead to come over the rim.

Solved
I tried stepping on it and rolling by hand, no luck.Ended up using an old bed slat to push the tire bead off the rim.

not particularly related, but sort of--Pedros tire levers are exceedingly tough, and while there is a larger "pry off doohicky" Ive seen photos of, these pedros levers are still smallish, but a heck of alot tougher than regular tire levers, and still packable in a seat bag or whatever.
if ever you see them at a store, they are worth the price of an icecream and coffee or whatever to have around.
I carry "regular ones" in my repair kit on bikes, but once in a blue moon, I use these at home with a difficult tire/rim combo that could perhaps break my smaller ones.

+1 on the Pedro's levers. My wife's bike has a tire/rim combination that is difficult (to say the least) to repair a flat on the trail (fortunately only happened once). Doubt that I could get the tire completely off the rim on the trail if I needed to. Make sure you're prepared for a flat away from home.
