Abstract
A mold design having a non-symmetric tread ring parting line is described that forms a tread pattern that extends onto the off-shoulder area of a tire on one side. The mold has a single tread segment that forms the entire tread pattern on the tire. The tread segment of the mold is non-symmetric in that one end, a first end, extends farther downward than the opposite end, a second end. The first end of the tread segment contains a tread pattern design capable of imparting a tread design on the off-shoulder or sidewall of one side of the tire to form a non-symmetric tread pattern.
