Measuring tire pressure in a tire mold
First Claim
1. A method comprising the steps of:
- (A) providing a bladder, a tire mold and, a green tire having a pair of annular beads and one or more plies;
(B) mounting a first pressure sensor to an inner surface of the green tire between an overlay and a belt;
wherein the first pressure sensor is a flexible printed circuit;
(C) inserting the green tire into the tire mold and closing the tire mold;
(D) shaping the green tire by expanding the bladder within the green tire against the closed tire mold; and
,(E) directly measuring the pressure between the overlay and the belt of the green tire during step (D) with the first pressure sensor.

Abstract
Pressure sensors may be used to directly measure the pressure between a green tire and a curing apparatus during shaping and/or during curing. This can be accomplished by a method including the steps of: (A) providing a bladder, a tire mold and, a green tire having a pair of annular beads and one or more plies; (B) mounting a first pressure sensor to an inner surface of the green tire between an overlay and a belt; (C) inserting the green tire into the tire mold and closing the tire mold; (D) shaping the green tire by expanding the bladder within the green tire against the closed tire mold; and, (E) directly measuring the pressure between the overlay and the belt of the green tire during step (D) with the first pressure sensor.
