Triangular bead construction for pneumatic tire with extended load carrying capacity |
摘要 |
<p>A pneumatic tire with an increased load carrying capacity (extended load index) but compatible with conventional, commercially available wheel rims, has a modified carcass ply line. The pneumatic tire (746) has a tread area (712) and a carcass structure (728) including two bead areas (750a,750b), at least one cord-reinforced elastomeric ply (730) extending through sidewalls (726a,726) between the bead areas (750a,750b) and the tread area (712), and a belt structure (718) between the tread area (712) and the carcass structure (728). The tire (746) has bead areas (750a,750b) containing triangular shaped beads so that the ply line (PL''') causes the bead areas to better secure the tire to the rim during high stress conditions. <IMAGE></p> |
