By a News Reporter-Staff News Editor at Journal of Transportation -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors KUNISAWA, Tetsuya (Kobe-shi, Hyogo, JP), filed on November 17, 2015, was made available online on September 28, 2017.

The assignee for this patent application is Sumitomo Rubber Industries, Ltd.

Reporters obtained the following quote from the background information supplied by the inventors: "In view of the increase in concern about environmental issues as well as economic efficiency, the demand for fuel efficient automobiles has been increasing in recent years. A need also exists for automotive tires excellent in fuel economy. Fuel economy is improved by reducing the amount of filler such as silica or carbon black to reduce rolling resistance. However, this technique tends to reduce wet grip performance and abrasion resistance. Automotive tires are also required to have handling stability, fatigue resistance, and tensile strength. Therefore, there is a need for techniques that achieve a balanced improvement in fuel economy, wet grip performance, handling stability, abrasion resistance, fatigue resistance, and tensile strength.

"The following methods have been proposed to date: a method of using an appropriate combination of a specific rubber component, silica, and inorganic powder such as aluminum hydroxide to simultaneously obtain performance on wet roads, abrasion resistance, and low heat build-up properties (see, for example, Patent Literature 1); a method of using an appropriate combination of a specific rubber component, a specific inorganic compound powder, and a specific carbon black to improve grip force on wet roads and semi-wet roads and workability (see, for example, Patent Literature 2); and a method of using an appropriate combination of a specific rubber component, a specific inorganic compound powder, a specific silica, and a specific carbon black to improve grip force on wet roads and semi-wet roads without impairing abrasion resistance (see, for example, Patent Literature 3). Unfortunately, these methods still leave room for improvement to achieve a balanced improvement in fuel economy, wet grip performance, handling stability, abrasion resistance, fatigue resistance, and tensile strength."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Technical Problem

"The present invention aims to solve the above problems and provide a pneumatic tire that achieves a balanced improvement in fuel economy, wet grip performance, handling stability, abrasion resistance, fatigue resistance, and tensile strength.

"Solution to Problem

"The present invention relates to a pneumatic tire, including a tread formed from a rubber composition, the rubber composition having after vulcanization rubber properties satisfying all the following relations (1) to (7):

"(tan .delta..sub.1/tan .delta..sub.2).gtoreq.4.38 (1)

"(E*/tan .delta..sub.2).gtoreq.21.88 (2)

"3.5.ltoreq.E*.ltoreq.6.0 (3)

"tan .delta..sub.2.ltoreq.0.16 (4)

"tan .delta..sub.1.gtoreq.0.70 (5)

"EB.gtoreq.600 (6)

"TB.times.EB.gtoreq.12000 (7)

"where tan .delta..sub.1 in relations (1) and (5) represents a tan .delta. at 0.degree. C. determined by viscoelastic measurement at an initial strain of 10% and a dynamic strain of 5%;

"tan .delta..sub.2 in relations (1), (2), and (4) represents a tan .delta. at 30.degree. C. determined by viscoelastic measurement at an initial strain of 10% and a dynamic strain of 2%;

"E* in relations (2) and (3) represents a dynamic elastic modulus (E*(MPa)) at 30.degree. C. determined by viscoelastic measurement at an initial strain of 10% and a dynamic strain of 2%;

"EB in relations (6) and (7) represents a tensile elongation (EB (%)) determined in accordance with JIS K 6251; and

"TB in relation (7) represents a tensile strength at break (TB (MPa)) determined in accordance with JIS K 6251.

"Preferably, the rubber properties after vulcanization of the rubber composition further satisfy the following relation (8):

"57.ltoreq.Hs.ltoreq.67 (8)

"where Hs represents a hardness (Hs) at 23.degree. C. determined in accordance with JIS K 6253.

"The rubber composition preferably contains at least one silica.

"Advantageous Effects of Invention

"The pneumatic tire of the present invention includes a tread formed from a rubber composition which has after vulcanization rubber properties satisfying all the above relations (1) to (7). Such a pneumatic tire can achieve a balanced improvement in fuel economy, wet grip performance, handling stability, abrasion resistance, fatigue resistance, and tensile strength."
