That is actually a very common error. The 40 series has a smaller diameter than the standard bow tie. The dirt bone, or standard bow tie is narrower, and provides better steering than a 40 series tire. I really liked the way they handled on the track today. The perfect tire will probably end up being the Traxxas response, or the Panther Python. They combine the benefits of both the regular narrow tire, and the low profile of the 40 series. I can only imagine how they will perform. I want them BAD!!!!

Matt, why you running the Q6's and DirtBones for smaller diameter meaning more off the line?
