Abstract: Tire-tread constructions may incorporate multiple circumferential asymmetries. Prime-number values are used for (a) the number of pitches (where a pitch is an individual pattern that is repeated around the circumference of the tire tread); (b) the number of segments of the mold with which the overall tire tread is formed; (c) the number of variations in the lengths of pitches; or (d) the number of variations in the lengths of the segments.

Abstract: A tire may be re-treaded utilizing a process in which a worn tread is removed from a casing. The worn tread had a first tread pattern. The casing has a tire body encapsulating at least one reinforcing belt, the at least one reinforcing belt embedded circumferentially in the tire body, the at least one reinforcing belt having lateral edges. The first tread pattern comprises a first plurality of universal bands of raised portions, where the first plurality of universal bands were situated over the lateral edges of the at least one belt. A new tread having a second tread pattern different from the first tread pattern is molded to the first casing. The second tread pattern comprises a second plurality of universal bands of raised portions that are situated in the same lateral locations as the first plurality of universal bands.

Abstract: A tubeless pneumatic tire/fluid reservoir assembly capable of being mounted upon a standard drop-center rim without deviation from standard mounting procedures for the tire alone. The tire contains an anchoring device comprising a reinforced strip having a first portion bonded and/or integral with the innerliner of the tire and a second portion that is affixed to the fluid reservoir. The fluid reservoir includes a hollow arcuate body capable of containing a fluid under pressure and capable of discharging same under coexisting predetermined conditions of pressure differential and temperature.
