The Bar Codes are a part of the JConcepts special breed of tire, designed for maximum performance when new or used as the design allows even wear all the way down to the tire body. Bar Codes in new condition excel on hard surfaces that have taken rubber with either dry or wet grooved conditions. Worn Bar Codes excel on indoor or outdoor clay tracks where a minimal dust groove has formed.

JConcepts now has the ultimate 1,2 punch by offering the V1 and V2 Bar Codes in a variety of compounds for tuning precision.
