Abstract
A pneumatic tire includes a body, a belt package, and a tread package. The tire includes a layer of rubber disposed between the body and the tread package. The layer of rubber creates a thickness of between about 0.5 millimeters and about 1.5 millimeters between the cords in the body and the cords in the belt package. The layer of rubber is fabricated from a rubber having a stiffness greater than the rubber in the body of the tire. This configuration provides a tire having improved cornering coefficient, reduced vibrational levels, and less coarse road noise with only a small increase in rolling loss.
Claims1
A pneumatic tire, comprising:
- a body including at least one layer of body cords;
- a belt package having at least one layer of reinforcing cords;
- a tread package connected to the belt package;
- and a gage of rubber disposed between the belt package and the body;
- the gage of rubber spacing the body cords from the reinforcing cords a distance in the range of 0.6 millimeters to 1.5 millimeters;
- the body further including a pair of sidewalls;
- each of the sidewalls having a sidewall rubber layer;
- the gage of rubber disposed between the belt package and the body being integrally connected to each of the sidewall rubber layers;
- the tire having a centerline;
- the gage of rubber extending only partially toward the centerline from the edge of the tire;
- each gage of rubber being tapered;
- the tire having a maximum width;
- each gage of rubber extending from the sidewall toward the centerline;
- the gage of rubber extending two-thirds of the distance to the centerline from the sidewall.
