An air maintenance tire assembly includes an air pumping passageway located within a tire sidewall to generate compressed air. An outlet screw assembly includes an elongate screw body residing within a profiled sidewall bore. The screw body extends through an axial span of the first sidewall to the tire cavity to conduct air from the sidewall air passageway to the tire cavity. The screw body has enlarged sectional end components to deter radial dislodging of the screw body from the sidewall bore during operation.

Outlet screw assembly for an air maintenance tire

An air maintenance tire assembly having an elongate air pumping sidewall air passageway includes an inlet air passage screw assembly inserted through a tire sidewall profiled bore to conduct air from outside the tire into a regulator positioned within a tire cavity. The screw assembly includes a screw body having at an outer end a large-diameter filter housing, a smaller-diameter midsection shank portion, and an inner large-diameter valve housing connecting to the regulator within the tire cavity. A valve mechanism seats within the valve housing and moves between an open position conducting air from the screw body into the regulator assembly and a closed position preventing a backflow of air from the regulator assembly.

Inlet air passage screw assembly for an air maintenance tire

The present application relates to a tire () comprising: a tread portion () and side walls (), said tread portion () and side walls () defining a main air chamber (); at least two auxiliary chambers () formed in the tread portion (); and an air transfer device () for transferring air between the main air chamber () and each of the auxiliary air chambers ().

Tripletube tire

A pneumatic tire having a tire tread is disclosed, wherein the tread comprises one or more tread elements and one or more grooves, the tread having a radially outer surface and a non-skid tread depth as measured from the radially outer surface of the tread and a radially innermost surface of the grooves. The tread has a radially innermost layer comprised of a base tread compound, a radially outer tread cap layer and a middle tread cap layer located between the base layer and the outer tread cap layer. Wherein the radially outer tread cap layer has a defined depth D, except that there is at least one notched areas wherein the tread cap layer extends radially inward of the defined depth D.

Tread made from multi cap compounds

A pneumatic tire having a tire tread is disclosed, wherein the tread comprises one or more tread elements and one or more grooves, the tread having a radially outer surface and a non-skid tread depth as measured from the radially outer surface of the tread and a radially innermost surface of the grooves. The tread has a radially innermost layer comprised of a base tread compound, a radially outer tread cap layer and a middle tread caplayer located between the base layer and the outer tread cap layer. Wherein the radially outer tread cap layer has a defined depth D, except that there is at least one notched areas wherein the tread cap layer extends radially inward of the defined depth D.
