Abstract
A pneumatic vehicle tire with at least two tread strips separated from each other by circumferential grooves and including belt-like reinforcements between the tread strips and the radial carcass while each tread strip has associated therewith a belt the width of which substantially corresponds to the width of the tread strips. Within the region of the belts, at least between these belts, there are provided thread-shaped strength carriers which together with the circumferential direction of the tire define an angle within the range of from 0.degree. to 10.degree..
Claims4
A pneumatic vehicle tire having a radial carcass and provided with at least two tread strips separated from each other by circumferential grooves having a width amounting to 20-50% of the width of the tread strips, which includes in combination:
- each tread strip having a belt-like reinforcement each including two fabric layers arranged radially inwardly of said tread strip symmetrically between the tread strips and said radial carcass so that each of said at least two tread strips has securely connected therewith a separate belt-like reinforcement each including the two fabric layers of which the width substantially corresponds to the width of each one of said tread strips, and thread-shaped strength carriers in a layer arranged within the region between said belt-like reinforcements and said radial carcass at least between said belt-like reinforcements radially inwardly of said grooves, said strength carriers together with the circumferential direction of said tire defining an angle within the range of 0.degree. to 10.degree. for strengthening area between said belt-like reinforcements stabilized against outward bulging due to internal tire pressure.
