Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A pneumatic vehicle tire including mounting beads and tire shoulders radially outwardly thereof which includes: a tread strip located centrally between the tire shoulders, annular pull resistant strength means arranged radially inwardly of said tread strip and extending edge to edge approximately over the width of said tread strip, and side walls having at least portions free from embedded strength members, said portions being provided with reinforcing ribs located close by to each other with spacing relative to each other corresponding approximately to rib width and located internally extending radially between respectively beads and as far as below only the edge of said annular pull resistant strength means with rib height diminishing toward opposite ends in an acute manner out of the ends thereof.
Claim 2
Dependent Claim
124 words
A pneumatic vehicle tire including mounting beads and tire shoulders radially outwardly thereof which includes: a tread strip located centrally between the tire shoulders, annular pull resistant strength means arranged radially inwardly of said tread strip and extending edge to edge approximately over the width of said tread strip, and side walls having at least portions free from embedded strength members, said portions being provided with reinforcing ribs located close by to each other with spacing relative to each other corresponding approximately to rib width and located internally extending radially between respectively beads and as far as below only the edge of said annular pull resistant strength means with rib height diminishing toward opposite ends in an acute manner out of the ends thereof.
Claim 3
Dependent Claim
24 words
A tire according to claim 1, in which the maximum height of said ribs approximately equals the thickness of the thinnest side wall portion.
Claim 4
Dependent Claim
22 words
A tire according to claim 1, In which the reinforcing ribs have a greater Shore hardness than the tire side wall proper.
Claim 5
Dependent Claim
32 words
A tire according to claim 3, in which the Shore hardness of said ribs is by from 10 to 20 Shore hardness degrees greater than that of the tire side walls proper.
Claim 6
Dependent Claim
20 words
A tire according to claim 1, in which the cross section of said reinforcing ribs varies along the length thereof.
Claim 7
Dependent Claim
40 words
A tire according to claim 1, in which the thickness of said side walls and of the reinforcing ribs therefor is so selected that said side walls together with the ribs pertaining thereto form supports of approximately uniform bending resistance.
Claim 8
Dependent Claim
15 words
A tire according to claim 1, in which said reinforcing ribs have a crescent contour.
