I'd say 2 in same color as wheels in middle stripe...like happy said maybe a little more narrow with the two outer stripes in black and maybe them a little more narrow as well. Maybe 1-2"...would have to play with that.
EDIT: Would probably also consider the reverse of the above color schemes.
Number two gets it for me, but I'm not sure what an argent stripe is that's being suggested. Number five is my second choice, but I'd want the larger of the two stripes a bit wider than it is in the rendering.
