First Claim
Patent Images
1. A pneumatic tire having an axis of rotation, the pneumatic tire comprising:
- a carcass including at least one continuous pressure membrane with a generally U-shaped cross section when viewed in a circumferential perspective relative to the axis of rotation of the pneumatic tire, the pressure membrane including a crown portion, a first sidewall portion, and a second sidewall portion connected with the first sidewall portion by the crown portion;
a rubber layer surrounding the carcass, the rubber layer including a tire crown with a tread; and
a belt disposed between the crown portion of the pressure membrane and the tread of the tire crown.
