This is the new uhhhhhhhh A001 beta prototype. Look at the excellent tread pattern that maximizes grip when cornering at high speeds below 10mph. It even has "Gold" written on the tire. You know you cant go wrong with gold. Also, this tire come with the specially forged Team Dynamics 0.1 racing wheel. Since this combo of 1 tire/wheel is heavier than all 4 of your current tires/wheels combined it will provide a much more solid and luxurious feeling when driving. For some unknown reason this model of wheel and tire was discontinued before it made it to production so you can only get this 1. $400.00 plus another $300.00 for special secured fragile shipping. This is priced to sell fast so dont sleep on it.
