Abstract
Abstract A pneumatic tire having a plurality of circumferentially extending ribs with circumferentially extending grooves separating each pair of ribs. Alternate circumferentially extending grooves extend radially inwardly for only about onehalf the depth of the non-skid portion and each has circumferentially extending and circumferentially spaced apart slots in its base which extend for the remainder of the depth of the non-skid portion.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
110 words
A pneumatic tire having a non-skid portion extending circumferentially thereabout, said non-skid portion including ribs extending circumferentially about said tire and grooves disposed between each pair of said ribs and extending circumferentially about said tire and having a ground contacting surface and base, the improvement wherein a first plurality of said grooves extends radially inwardly from the ground contacting surface of the non-skid portion only part of the distance to the base of the non-skid portion and are provided with a plurality of recesses in the base thereof said recesses being spaced apart longitudinally of said first set of grooves a distance about equal to the length of adjacent recesses.
Claim 2
Dependent Claim
110 words
A pneumatic tire having a non-skid portion extending circumferentially thereabout, said non-skid portion including ribs extending circumferentially about said tire and grooves disposed between each pair of said ribs and extending circumferentially about said tire and having a ground contacting surface and base, the improvement wherein a first plurality of said grooves extends radially inwardly from the ground contacting surface of the non-skid portion only part of the distance to the base of the non-skid portion and are provided with a plurality of recesses in the base thereof said recesses being spaced apart longitudinally of said first set of grooves a distance about equal to the length of adjacent recesses.
Claim 3
Dependent Claim
18 words

Claim 7
Dependent Claim
65 words
A tire as claimed in claim 1 including a shoulder rib at each lateral edge of said non-skid portion and in which each circumferential rib other than each said shoulder rib is bounded on one side by a circumferential groove which extends for substantially the full depth of the non-skid portion and on the opposite side by a groove of said first plurality of grooves.
Claim 8
Dependent Claim
19 words
A tire as claimed in claim 6 in which said recesses are slots extending longitudinally of their respective groove.
Claim 9
Dependent Claim
26 words

Claim 11
Dependent Claim
24 words
A tire as claimed in claim 8 in which the two laterally outermost circumferential grooves extend approximately one-half the depth of the non-skid portion.
Claim 12
Dependent Claim
20 words
A tire as claimed in claim 10 in which said slots extend along the longitudinal centerline of their respective groove.
Claim 13
Dependent Claim
104 words
A pneumatic tire having a non-skid portion extending circumferentially thereabout, said non-skid portion including ribs extending circumferentially about said tire and grooves disposed between each pair of said ribs and extending circumferentially about said tire and having a ground contActing surface and base, the improvement wherein a first plurality of said grooves extends radially inwardly from the ground contacting surface of the non-skid portion to between 30 and 70 percent of the distance to the base of the non-skid portion and are provided with a plurality of recesses in the base thereof said recesses being spaced apart longitudinally of said first set of grooves.
Claim 14
Dependent Claim
104 words
A pneumatic tire having a non-skid portion extending circumferentially thereabout, said non-skid portion including ribs extending circumferentially about said tire and grooves disposed between each pair of said ribs and extending circumferentially about said tire and having a ground contActing surface and base, the improvement wherein a first plurality of said grooves extends radially inwardly from the ground contacting surface of the non-skid portion to between 30 and 70 percent of the distance to the base of the non-skid portion and are provided with a plurality of recesses in the base thereof said recesses being spaced apart longitudinally of said first set of grooves.
