Pro-Line's Evil Twin tire design is being released to redefine the blue-groove and hard-packed surface tire choice. R/C enthusiasts, as well as, seasoned pros have come to know that blue-groove, hard-packed racing is here to stay. With that in mind, the Evil Twin tire, which was designed off of the multi-National and World Champion Square Fuzzie, demonstrates ultimate performance on blue-groove, hard-packed surfaces. Long center bars produce the forward bit needed, while reducing tire wear, therefore, increasing tire life. The pins represented on the Evil Twin also produce forward bite while managing side-to-side traction to its fullest. Pro-Line performance off-road tires…simply the best!
