摘要： The tire (70) of the invention incorporates a carcass ply cord material (93) with variable modulus of elasticity to provide an active sidewall structure (82a, 82b). The variable modulus cord material is incorporated in the axially outwardmost ply (90) of a carcass (80) having two plies (88, 90) separated by elastomeric inserts (89a, 89b) in the sidewalls (82a, 82b). The outer ply cord material (93) provides an increased modulus of elasticity with an increase in elongation. The inner ply cords (91) have a modulus that substantially exceeds that of the outer ply cords (93) under normal loads in the inflated mode. Thus, the inner ply (88) dominates the structural response of the sidewalls (82a, 82b) at normal loads in the inflated mode. Under severe sidewall deflection, such as when the tire is uninflated, the outer ply cord (93) is elongated, increasing its modulus of elasticity and thus, shifting the load from the axially inwardmost ply (88) to the axially outwardmost ply (90).

摘要： A very light weight tire (10) has at least one radial ply (38) and an aramid belt structure (36), having two single cut belt layers (50, 51) covered by an overlay (59) having cords (80) selected from the group of aramid, rayon, PEN, PET and PVA. The tire (10) has a very thin or reduced gauge (t) undertead (13). The tire (10) can be made having very low rolling resistance due to the combination of casing structure and the reduced rubber mass.

摘要： A pneumatic radial ply tire (86, 104) having a tread (106), a carcass (96, 108) with two sidewalls (88a, 88b, 116a, 116b), a radial ply structure (98, 110), and a belt structure (103, 117) located radially between the tread and the radial ply structure. Each sidewall is reinforced with at least one wedge insert (89a, 89b, 118a, 118b, 120a, 120b) which comprises alternating regions (90a, 90b, 122a, 122b) of flexible material and layers (91a, 91b, 124a, 124b) of stiffer material. The layer (91a, 91b, 124a, 124b) of stiffer material constrain the lateral expansion of the wedge insert (89a, 89b, 118a, 118b, 120a, 120b) during runflat operation to provide good riding comfort during normal inflation operation and good sidewall reinforcement during runflat operation.
