Abstract
The present invention is directed to A plurality of vehicle tires having tread patterns of substantially the same outer appearance, wherein the tread patterns comprise a primary tread pattern comprising blocks and/or ribs separated by broad cut-outs and a secondary tread pattern on the blocks and/or ribs of the primary tread pattern comprising fine cuts. At least one vehicle tire has fine cuts of low depth and at least one different tire has sections of the fine cuts that have a different depth of fine cuts. The at least one vehicle tire has different driving characteristic from the at least one different vehicle tire. The advantage of the vehicle tires of the present invention is that a performance characteristic of the tire can be chosen by altering the structure of specific sections of the tire, without varying the fundamental opial appearance of the tire.
