Are those the Bar Code front tires? Because those fronts look nothing like the Bar Code rears. I was hoping that J Concepts was gonna make Bar Code fronts that have the same tread pattern as the rear. What they need to do is make rears that have the same tread pattern as those fronts to use on "taper pin tracks" I thought the only reason everyone runs the BK Bar rear Taper Pin front combo was because losi didn't make BK Bar fronts. I thought J Concepts was an "outside the box" company? Now, if they did testing and found that front tires with a "Bar Code" pattern just didn't work and the "tapered pin" design did, then I retract my previous statment.
