The CITYBLOCK was the first pin on block design tire and sparked a host of copies across the industry. This innovative approach to tread design launched a tire that is unmatched in its versatility. From loose dusty tracks to high bite hard packed tracks the CITYBLOCK will deliver consistent performance and has become the work horse of the AKA tire line. You can't go wrong with a set of these in your tire collection. Super Soft long wear is developed to work in colder conditions where the track either has an abrasive surface or a surface that gets very polished which creates lots of wheel spin and therefore more wear. This compound will be popular in the winter months where drivers are still competing on outside tracks in cold weather.
