20090048400 | Method for Making Tire with Black Sidewall and Tire Made by the Method - The present invention is directed to a method for maintaining the black sidewall appearance of a tire, comprising the step of fabricating the tire with a rubber sidewall compound comprising 100 parts by weight of at least one diene based rubber; from 10 to 70 parts by weight, per 100 parts by weight of diene based rubber (phr) of a rubber process oil selected from the group consisting of aromatic, paraffinic, naphthenic, vegetable oils other than castor oil, and low PCA oils including MES, TDAE, SRAE and heavy naphthenic oils; and from 0.5 to 3 parts by weight, per 100 parts by weight of diene based rubber (phr) of a triglyceride derived from fatty acids comprising at least 80 percent by weight of at least one of ricinoleic acid and 12-hydroxy stearic acid. | 02-19-2009 |
20100116388 | TRUCK RACING TIRE - The invention is directed to a pneumatic radial ply truck tire having a tread with a tread depth D, at least two circumferential grooves dividing the tread into at least a first shoulder circumferential rib, an intermediary circumferential rib, and a second shoulder circumferential rib, the tire being characterized by the tread having a base region disposed at depth D and a cap region over the base region, the base region and the cap region adjoining along a boundary, the cap region comprising a cap rubber composition having properties measured at 23° C. of: elongation of 400 to 500%, true tensile of 77 to 83 MPa, 300% modulus of 9 to 11 MPa, tensile strength of 14 to 15 MPa, shore A hardness of 63 to 68, rebound of 20 to 25%; and the base region comprising a base rubber composition having properties measured at 23° C. of: elongation of 470 to 520%, true tensile of 135 to 150 MPa, 300% modulus of 13 to 15.5 MPa, tensile strength of 22 to 25 MPa, shore A hardness of 63 to 67, rebound 50 to 55%. | 05-13-2010 |
20120136110 | PREPARATION OF RUBBER CONTAINING SILICA AND CARBON BLACK REINFORCEMENT, RUBBER COMPOSITION AND TIRE WITH COMPONENT - The invention relates to preparation of a rubber composition containing silica and carbon black reinforcement, the resultant rubber composition and tire with component comprised of such rubber composition. | 05-31-2012 |
20130030658 | ADJUSTABLE TIRE PRESSURE SYSTEM AND METHOD - A tire adjustment system and utilization means therefor includes a vehicle having at lone or more electronic vehicle control systems such as an anti-lock brake system; steering wheel control system, electronic stability system; suspension control system; global positioning system. An electronic valve system is mounted to operatively adjust on a tire-by-tire basis the inflation pressure within each tire cavity responsive to an electronic input signal from at least one of the vehicle control systems. The inflation adjustment of each tire alters the tire tread footprint configuration to optimally correlate with one or more identified current road condition(s) traversed by the vehicle. | 01-31-2013 |
20130153101 | TRUCK TIRE WITH RUBBER TREAD - This invention relates to a tire with a circumferential rubber tread comprised of a rubber composition for promotion of reduced internal heat build-up. The invention particularly relates to truck tires. | 06-20-2013 |
20130163368 | APPARATUS AND PROCESS FOR MIXING RUBBER COMPOUNDS - A mixing apparatus for manufacturing a rubber compound is disclosed. The mixing apparatus comprises a plurality of multiple shaft extruder devices, each comprising at least one inlet for receiving a plurality of materials to be fed into the extruder device and an outlet for discharging a mixed material extruded by the extruder device. The multiple shaft extruder devices are either arranged in such a way that operatively the extrudate of at least one of the plurality of multiple shaft extruder devices can be fed into the inlet of at least one other of plurality of multiple shaft extruder devices, or are arranged to operate in parallel in such a way that operatively the extrudates of the plurality of multiple shaft extruder devices can be fed together into the inlet of at least one further mixing device. | 06-27-2013 |
