How long does it take for tile to dry out after a rain, and do they get slippery and squishy?

Since our Flagstone Rubber Pavers are made of rubber, they are actually more slip-resistant when wet than dry. They will not get squishy when wet and dry fairly quickly after a normal rainstorm. We don't have any drain rate testing for these tiles, but they are porous, so they will drain fairly quickly.
