Patent number: 6834696Abstract: A runflat tire is provided that may be used in applications currently requiring a large aspect ratio tire. The runflat tire of the invention may be substituted in these applications while providing desirable ride characteristics. The runflat tire includes a sidewall with a radial portion and a cantilever portion. The cantilever portion may be fabricated by extending a sidewall insert in the axially inward direction or by extending the bead filler in the axially outward direction. In other embodiments, the cantilever sidewall portion is formed by a combination of the sidewall insert and the bead filler. The resulting runflat tire has desired durability in the uninflated operating condition while having desired ride characteristics in the inflated condition. The sidewall structure allows the tire to be used in applications presently requiring a tire with a high aspect ratio.Type: GrantFiled: June 29, 2000Date of Patent: December 28, 2004Assignee: Bridgestone/Firestone North American Tire, LLCInventors: Martin A.

Patent number: 6769294Abstract: The invention provides a tire and a method for analyzing the temperature exposure to the tire. The tire and the method allow an investigator to determine the maximum temperature the tire experienced during its operation. This information offers a potential cause for the tire failure by allowing the investigator to determine a maximum temperature experienced by an area of the tire by reviewing a non-reversible, temperature-indicating label positioned at a location in the tire. The information may be used to identify a potential cause of a tire failure after the failure has occurred. The information may also be used to identify a damaged tire before the tire fails.Type: GrantFiled: September 7, 2001Date of Patent: August 3, 2004Assignee: Bridgestone/Firestone North American Tire, LLCInventors: Martin A. Yurjevich, James M. Kirby, Charles D. Spragg, Andrew K. Reinhart

Patent number: 6546791Abstract: Method and apparatus for conducting indoor hydroplaning tests on a tire. A tire is supported by a frame above a test surface and a load is applied to the tire tread against the test surface. A stream of high pressure fluid is discharged from a nozzle against an area of contact of the tire tread and the test surface. A device detects a change in the loaded contact of the tire as the pressure of the fluid stream increases which provides an indication that hydroplaning is beginning to occur in comparison with a previously tested tire under actual driving conditions.Type: GrantFiled: August 8, 2001Date of Patent: April 15, 2003Assignee: Bridgestone/Firestone North American Tire, LLCInventor: Martin A.

Patent number: 6155110Abstract: A method of testing a tire for rain groove wander is provided which allows a tire to be objectively tested in a laboratory wherein the objective test results closely correlate with subjective field analysis type data, thereby allowing for the subjective tire performance to be predicted while precluding the need for subjective field analysis of the particular tire. The method also allows objective testing of a single tire size by varying the radial loading in the laboratory test set, thereby precluding the construction of multiple tire sizes each having the same tread design. The method simulates rain groove road conditions and correlates objective analysis data obtained via the laboratory test methodology with subjective field analysis data of rain groove wander tire performance of other tires, thereby providing a substantially accurate technique for identifying the subjective performance of the tire without having to conduct the field testing to obtain such subjective field analysis data.Type: GrantFiled: April 24, 1997Date of Patent: December 5, 2000Assignee: Bridgestone/Firestone, Inc.Inventors: John G.

Patent number: 5448910Abstract: A portable machine for testing on site the uniformity of a tire or other components of a tire/wheel assembly. A compact rigid frame has a base formed by a plurality of longitudinal and transverse frame members for supporting the machine on a planar surface. A box-like subframe is mounted on the base and supports a mounting plate for the tire/wheel assembly. The mounting plate is slidably mounted on a pair of slide rods extending upwardly from the subframe. A road wheel and drive motor are mounted on the base, with the motor being mounted within the subframe and the load wheel being located beneath the tire/wheel assembly mounting plate. An air spring raises and lowers the mounting plate for placement and removal of a tire/wheel assembly thereon. A loading mechanism applies a force on the tire/wheel assembly mounting plate to forceably move a tire into contact with the road wheel, and is measurable by a first load cell.Type: GrantFiled: March 7, 1994Date of Patent: September 12, 1995Assignee: Bridgestone/Firestone, Inc.Inventors: Martin A.
