Abstract
An insert for a pneumatic tire including an annular member adapted to contact at least 10% of an interior surface of the pneumatic tire and provide an outward pressure thereagainst.
Claims17
An insert for a pneumatic tire assembly comprising:
- a tire mounted on a rim, the tire having opposed sidewalls interconnected by a tread portion and the tire defining an interior volume with a width WPT and an interior surface;
- an annular member having a base portion, an outer portion and opposed side portions, wherein the annular member is inserted into the interior volume of the tire so that there is an empty space between the outer portion of the annular member and the interior surface of the tire at the tread portion and there is an area of contact between the opposed side portions of the annular member and the respective opposed sidewalls of the tire;
- wherein the annular member has a width WAM that is greater than WPT as measured prior to insertion of the annular member into the interior volume of the tire, and the annular member exerts an outward pressure against the tire over the area of contact between the opposed side portions of the annular member and the respective opposed sidewalls of the tire.
An insert for a pneumatic tire having an interior surface, a tread portion and opposed sidewalls with a width therebetween, comprising:
- an annular member having a base portion, an outer portion and opposed sidewalls, the annular member adapted to be assembled with the tire so that the annular member contacts less than 80 percent of the interior surface of the tire and provide an outward pressure against the opposed sidewalls, and
- wherein at all locations where the annular member contacts the interior surface of the tire when the annular member has been assembled with the tire, the annular member has a width that is greater than the width between the opposed sidewalls when measured prior to assembly of the annular member with the tire;
- and
- wherein the annular member laterally stabilizes the tire sidewalls.
1 more element
A tire assembly comprising:
- a pneumatic tire having opposed sidewalls with a width therebetween and interconnected by a tread portion and an interior surface interiorly of the sidewalls and the tread portion;
- an annular foam member having opposed sidewalls contacting less than 80 percent of the interior surface the thereby define an area of contact between the foam member and the interior surface when the annular foam member is assembled with the tire, and wherein a width of the foam member over the entire area of contact prior to assembly with the tire is greater than the width between the opposed sidewalls over the entire area of contact so that the foam member exerts an outwardly directed pressure against the opposed sidewalls of at least 0.1 psi.
