Drivers ask what is the best performing all around tire in most conditions, without a doubt the Crowbars are the choice.  It doesn’t matter if the track is wet, loamy, dry or blue grooved the Crowbars are safe and offer racers a confidence inspiring performance.  The heart of the Crowbar design is the center lug design which is a combination of hefty size lugs, half-height bridges and slim cuts which induce added flex and traction. 

The majority of the tire is made of precisely spaced hefty lugs which rotate out to the outer edges of the tires.  JConcepts did not miss a detail as the outer lugs have already been clipped at a convenient angle for a smoother driving feel and transition.   Crowbars are a world leading tire combination right out of the package, the unique Crowbar lug technology combined with the sticky yellow and blue compound allow the flexibility necessary to compete on even the most demanding surfaces for an extended period of time.
