I mean ceramic breaks so how do ceramic bearings not break?
Unless you're riding a high performance sport bike and ride it like you stole it (LOL), matching the front and rear tires is not crucial. The average rider won't know the difference riding on mismatched tires.
The manufacturers don't have to match, just the tire sizes for what you are switching out. I have a Kenda on the front and a Metzler on the back. You can get them matched if you want, but it's not a requirement.
I just replaced my rear tire only because my type of bike usually goes through two rears to one front. You don't have to get the exact make that came with your bike, but size is much more important. Don't change that unless you know exactly what you're doing. Whoever sells/mounts it for you can help with that as you don't give info on the bike.
Ceramic objects break because they are brittle and subjected to shock, but ceramic material can be hard and strong in compression. So a properly designed bearing will provide a smooth running lubricated surface and take considerable force and if spring mounted will not be subject to high instantaneous force because its mount will move away.
