      The rubber in tires is compounded with carbon black to help it resist abrasion and UV light, and also gives it its black color.

      With out seeing it, i would say it is brake bust off of your disc brakes. Does it clean off like dust? If brake dust, you are driving to harshly and braking to much.

      He actually wants to know why tyres are black in colour. I have adjusted the title and original post to make this clear.

      Scientifically, tires are black and it's because carbon basically improves the strength of the tread wear resistance to rubber. Likewise, black is a carbon powder added to the rubber.

      Carbon black additive made by incomplete combustion of heavy petroleum - Primarily an additive and heat dissipating agent added to natural rubbers while manufacturing tires - Reason for black color !

      Despite the fact that the regular shade of elastic is a smooth white, the dark shading we see was initially caused by residue. ... Once added to the elastic, carbon blackincreases the quality and toughness of the tires, which is naturally observed as an alluring attribute fortyre makers and vehicle drivers

      I'm really surprised that this isn't a more popular thing. Surely the practical benefits can easily be recreated in any colour and I reckon many people would pay a large premium to have their tyres match their bodywork!
