JConcepts have released their Mambos wide-body RC drag racing tire in a super soft green compound for cooler days and their popular gold compound for 90º+ temps or for prepped surfaces. At the heart of this design is the 2.2 x 3.0” configuration but stretched out to create a larger contact patch. Forward traction is the name of the game and the goal of the larger area, in theory, gives a racer a slight advantage in the ‘hook and go’ department. One of the tricky aspects to drag racing rear tires is tire expansion and controlling this aspect of power and acceleration. The JConcepts design team thickened the entire carcass, added new inner sidewall ribbing on the inside and outside and then an industry first waffle inner weight reduction pattern. The waffle pattern accomplishes 2 things, weight reduction and provides some resistance to expansion to split some difference between a heavily restricted belted tire and a tire with no inner structure.
