I've made a few tiles now, but when their finished (glued and painted) and I put them to dry the tiles are bend the next day. Anyone an idea how to avoid/prevent this problem?

Are you using heat to dry? This will cause bending.
Are your tiles extremely wet when you set them to dry? This will cause bending.
You can rebend the tiles without making them ugly by putting a bend in the bottom part of the cardboard (the top will be slightly harder to bend b/c of the paint - but only slightly, so be ginger).
Some people have suggested gluing strips on the bottom side to increase their strength.

...Another option is to hot glue a second tile the same size to the bottom of the tile but I just reverse bend them back into shape. You can also try turning them over and putting a weight on them while they are drying.

I'm gonna glue a second tile on the bottom reverse grain of the cardboard of the first tile. See if that works. I don't dry the tiles using heat but the tiles are wet of course. Thanks for the advice everyone!

Over usage of liquid seems to be the culprit based on what you just said. Try to develop a method to use less paint in general, or find a better paint product (Some paints are more liquidy). Also, humidity in the air (Or lack thereof) has odd effects on the drying of paint and other substances, so keep that in mind...if you come from a humid climate, consider finding a place that is drier than where you usually leave things out. Also, cellars, laundry rooms, and spaces where water heaters are kept can result in problems too...don't leave items to dry in those areas.
Finally, using thin dowels or metal bars threaded through the corrugation of the cardboard (The wavey stuff in the middle between the two plys of cardstock) can prevent some warping if done in the correct direction. Unfortunately, most cardboard warps in such a way that this method won't help, so you may have to *carefully* pierce through the tile perpendicular to the corrugation.
Another potential method is getting a rigid structure to bind the tile to while drying...a few methods of how to do this may be possible without making it a permanent arrangement, but I'm at a loss as to how without usage of alligator clips, string, or tape, all of which may leave unsightly marks on your tile once the drying process is completed.
Anyway, I hope some of these ideas help.

Another thing you might try is painting the bottom of the tiles. The bend is from the shrinkage on one side... so if you paint the opposite side it will often balance out and stay flat. Just a quick coat of flat black should do it, though that might seem like a waste of paint (craft paint is pretty cheap).
