Abstract: A run flat tire has a plurality of reinforcing wedges located in the tire sidewall with the hardness of each wedge generally diminishing in the radially inward direction of the sidewall. Since the bead filler is harder than the radial innermost wedge, the hardness at generally the top of the bead filler increases in the radial inward direction. The reinforcing wedges partially overlap each other and can generally have any configuration. The changing of hardness of the radial wedges results in a wedge sequence and thus a more even strain distribution throughout the tire sidewall. This strain distribution extends the run flat life of the tire and also provides a good balance with other tire performance parameters.

Abstract: A run flat tire has a plurality of reinforcing wedges located in the tire sidewall with the hardness of each wedge generally diminishing in the radially inward direction of the sidewall. Since the bead filler is harder than the radial innermost wedge, the hardness at generally the top of the bead filler increases in the radial inward direction.

The changing of hardness of the radial wedges results in a wedge sequence and thus a more even strain distribution throughout the tire sidewall. This strain distribution extends the run flat life of the tire and also provides a good balance with other tire performance parameters.
