Our target market is retail sales and installation of tires in urban markets so we want to focus on clean and easy to read and recognize. As much as I like #15 - It doesn't target the market we are wanting to appeal to with this service. The font used in 10 & 11 is not as clean and clear as we would like.
Like #19 - How about changing blue to black. Lets also try switching red to orange. Also, slightly increase the angle of the letters in an effort to show movement.
