Tires with improved drainage and noise reduction performance

摘要

The present invention relates to a tread having a plurality of grooves formed on a tread to change the structure of circumferential grooves so as to allow quick drainage when the vehicle is running on a wet road surface and also to prevent a regular flow of air generated between a ground surface and a tire The purpose of the present invention is to provide a tire which can be used.;The tire according to the present invention has a plurality of circumferential grooves GR1, GR2 and GR2 having a tread pattern tread on the tread T, wherein the circumferential grooves GR1, GR2, It is also possible to form the low depth unit grooves G1 and the plurality of high depth unit grooves G2 by alternately connecting the lowermost unit grooves G1 and the lowermost unit grooves G2 and by slanting the connecting portions S of the unit grooves, So that the running stability and the noise reduction can be achieved.
