摘要 |
The present invention relates to a pneumatic tire having a tread with a plurality of load-supporting elements placed above the circumference of the tire. The tread is characterized by a pitch sequence comprising (a) from 67 to 103 total pitches; (b) only four or five different pitch lengths; (c) a ratio of the longest pitch to the shortest pitch length not to exceed 1.58; (d) a ratio of the longer pitch length to the shorter pitch length of any two pitches which precede or follow each other not to exceed 1.43; (e) there being no instance in the pitch sequence where the shortest pitch length directly precedes or directly follows the longest pitch length; (f) there being a constant increment in pitch length in the four or five different pitch lengths as one progresses from the shortest pitch length to the longest pitch length.
