Aggregate
The Aggregate is the optimal all-around tire for paved, hardpack, and light gravel terrain. The evenly spaced knobs speed over smoother surfaces with minimal vibration while their hexoganal shape provides predictable handling over looser conditions. That is combined with our signature Rubberforce G tread compounds for impressive grip in the dirt and the new Stage 5S Armor construction offers both supreme ride quality and abrasion resistance.

Some American Classic tires are compatible with hookless (Tubeless Straight-Side/TSS) rims. To be compatible, the following must be met:
- The tire must be a Tubeless-Ready model,
- The tire must not include Stage 3 Flat Protection or Stage 3S Flat Protection,
- The tire must be placed on an appropriate width rim,
- The rim must meet current E.T.R.T.O. standards for tubeless systems, and
- The air pressure must be below the lowest maximum pressure as listed by both the rim and the ISO recommended pressure for Tubeless-Ready tires on hookless rims.
More information on hookless compatibility can be found on our Tire and Rim Compatibility page.
