Bit Char-G or Bit Racer tires?

[Bootylactin]

Apart from the color, are there any differences between these two sets of tires? It appears both have hard, medium, and soft. Is the tread the same on both sets? Anybody tried both and found differences in the performance?

It seems the Bit Racer tires are more readily available than the Bit Char-G, and I'm trying to figure out which to purchase.

Thanks in advance for any information you can provide!
