Info on mounting the JConcepts Bar Codes:
Much work was put into the details of the Bar Code truck tire so that customers would have more than one mounting option.
After many months of testing we determined that in the rear the "Y" side bars should be mounted on the outside of the wheel. This typically results in more side bite and the truck being more stable from the rear.
We recommend that the "Y" shaped bars be mounted on the inside of the wheel in front as this provides the truck with more initial bite/turn in.
Although we tested on many surfaces/conditions, please experiment with these mounted in different directions to best suit your local track/condition.
