Mounted on the all new large diameter Prism wheel. 37mm diameter rim in the front and 38mm in the rear. Fronts are trued to approximately 1.80" (45.7mm) and rear to 1.90" (48.2mm). These revolutionary tires come trued to a race-ready diameter and are available in a variety of new compounds. The best part is less rubber on the wheel means a lower price to the consumer. That's a "win-win" scenario.
Jaco, 1/12th scale tire chart. Use this chart to enhance your racing program.
Black - 40 shore: This is a low natural rubber compound. Special tire for insane traction carpet tracks. Does not get gummy like Purple. If you don't have insane traction you car will likely push with these.
Purple - 40 shore: This is a natural rubber compound. Popular front stock tire, carries good corner speed because it's firm. The foam this compound is made from gets more gummy late in a race. The more you run this compound the gummier and stickier it gets. A little more forgiving than some of the other fronts.
Lilac - 37 shore: This is a natural rubber compound. Great front tire for stock carpet or if dbl. pink is too much steering.
Double Pink - 35 shore: This is a natural rubber compound. This is the standard front tire for carpet in all classes. Its is used front and rear for 19T and Mod carpet and front and rear in all classes on asphalt.
Grey - 35 shore: This is a low natural rubber compound. It is just as hard as dbl. pink but it has FAR LESS traction. It is used to free up the rear of stock powered carpet cars for more efficiency and corner speed. This is the old standard rear carpet tire, most stock carpet racers use the Softer yellow compound now for more forward grip.
Magenta - 32 shore: This is a natural rubber compound. Its Softer than dbl pink so if you need more steering than dbl. pink use these up front. If you need more rear traction than dbl. pink use these in the rear.
Pink - 30 shore: Pink - 30 shore: This is a natural rubber compound. This tire is used in mod 1/12th on carpet and asphalt if the traction is low. If the traction is high it will lock in the rear of the car and make it push.
Yellow - 30 shore: This is a low natural rubber compound. It is the standard rear tire for Stock racing. It is used to free up the rear of stock powered carpet cars for more efficiency and corner speed.
