It's all in the name: ThickSlick. The tire features a burly casing designed to withstand the roughest urban conditions, paired with a slick tread design that provides the bite you need in the concrete jungle with impeccable style. The Extra ThickSlick tread resists punctures and gets great wear life. It is a favorite of fixie riders and is now available in a multitude of sizes. The tire has twice the amount of tread rubber than standard slick road tires.
