true, i don't skid the **** out of my tires because there's no point... i skip to stop most of the time or just go through the red lights. i mean, my rear tire has flat spots all over the place, i deifnitely need new tires, but trying to find out what tire skids easier is still worthless... you need to buy your tires for riding performance... they all skid. who cares if it skids well if you can't hold yourself in a sharp turn.
you are, however, correct that higher pressure will make the skid easier.
