摘要： Disclosed herein is a tire including a reinforcing rib (200) formed on a groove (100) to prevent the irregular wear of a tread (10) and including an auxiliary hidden groove (110) formed in the groove (100) to enhance the capabilities of water absorption and drainage of the tire even when the reinforcing rib (200) is formed on the groove (100). The tire for preventing irregular tread wear includes a reinforcing rib (200) coupled to a first sidewall (101), which is one of both sidewalls (101, 102) forming the groove (100), and protruding toward the groove from the first sidewall, a hidden groove formed in one portion of a second sidewall which is the other of the sidewalls forming the groove, and a remaining tread part protruding toward the groove from a side surface of the hidden groove, the remaining tread part being the other portion of the second sidewall.

摘要： A tire (100) includes a radio frequency identification (RFID) system (180) and a rubber patch including a topping rubber (181a, 181b) topping the RFID system, wherein the topping rubber includes a raw material rubber and a reinforcing filler including a boron nitride. In the tire including a RFID system, since the RFID system is covered with a rubber similar to a nearby rubber, generation of a boundary therebetween is suppressed to lower a possibility of the occurrence of initial cracking at a portion where the RFID system is applied, thus increasing durability and safety, and since insulating properties of the rubber covering the RFID system are enhanced, a recognition distance of the RFID system is increased to further facilitate management of distribution and history.

摘要： A rubber composition for tire tread, and a tire manufactured using the rubber composition are provided. The rubber composition for tire tread include 100 parts by weight of a raw material rubber; 2 to 30 parts by weight of a liquid polymer containing double bonds in the main chain at a proportion of 10 mol% to 90 mol%; 2 to 30 parts by weight of a hydrocarbon resin; and 80 to 180 parts by weight of a reinforcing filler. The rubber composition can provide a tire which has the steering and braking performance on a wet road surface and an icy and snowy road surface simultaneously improved and in which the occurrence of lamination cut-chip is prevented.

摘要： The present invention relates to an ultra super single tire for heavy duty. The ultra super single tire for heavy duty of the invention includes a tread (110) that contacts the road surface; a carcass (120) that constitutes the skeleton of the tire; and a belt layer (130) that is disposed between the tread (110) and the carcass (120), in which the belt layer (130) is composed of a first belt to a fourth belt that are laminated sequentially from the carcass (120) toward the tread (110), the first belt (131) includes an extender belt (131b), and the second belt (132) is a wide spiral coil belt. The present invention exhibits effects of preventing an excessive increase in weight, the occurrence of excessive heat generation, and deterioration of durability, further enhancing the ground contact length at the ground contacting center, and further enhancing the durability at belt layer edges, by means of a wide spiral coil belt having a four-layer belt structure, in which the order of lamination of the helical coil has been changed and the width has been increased, and by means of an extender belt.

摘要： Disclosed is a pneumatic tire for reducing noise that can more effectively reduce cavity noise energy, which is generated by vibration of air filling the tire upon rotation of the tire resulting from car driving, and a frequency generated thereby.
Provided is a pneumatic tire with reduced cavity noise including a porous sound-absorbing material adhered by an adhesive agent layer to an inside surface of an inner liner disposed in a tread layer in the tire,
wherein the sound-absorbing material is continuously extended in a circumferential direction in the tire and is disposed such that an adhesion starting point finally contacts an adhesion end point, or is spaced from the adhesion end point so as to face each other, the sound-absorbing material has an open cell on a surface thereof, a volume of the sound-absorbing material is 14% to 26% with respect to a total volume of the tire, wherein the total volume of the tire is defined as a volume of an area extending from a bottom surface of a tread to under a rim, and a maximum width of the sound-absorbing material is 35% to 60% with respect to a width of the tire tread and a surface area of the sound-absorbing material is 10% to 50% with respect to a surface area of the rim of a wheel on the surface of the inner liner to which the sound-absorbing material is adhered.
In accordance with the present invention, there is an advantage of more effectively reducing noise in tires by changing a noise energy causing resonance and a frequency generated by the energy.-
