Because its the only decent one i had lying around at the time, & i cant really justify buying a new cable for the sake of the colour, im not that vain.
Its quite hard, i can take most bmx tires of with my fingers but these i have to get started with tire levers, probably due to how freaking wide the rims are.
You must be doing it wrong then, ive had no problems with any other tires (oddy,shadow,wtp & revenge industries) all you have to do is pinch the bead and move the rest of the tire to the centre of the rim and you can get them of with your hands, its also best to start of around the valve hole where the rim is slightly lower.
