USTMA members strive to increase the use of sustainable materials in the tires we manufacture

Tires contain many rubber compounds and other materials because they are required to safely perform in the face of a wide range of demanding conditions. Compounding–the process of selecting and combining materials for a specific tire component–is complex.

The specific makeup of each tire compound is dictated by how and where it will be used within the tire — tread or sidewall, structural plies or stabilizing bead — and the specific safety and performance attributes desired. Improved sustainability performance must complement these essential attributes, an opportunity and a challenge USTMA members have embraced.

USTMA members work to incorporate more sustainable materials into tires, enhancing biodiversity and reducing dependence on non-renewable feedstocks.

Bridgestone, Cooper and Pirelli have conducted major research on the commercial potential of guayule, a shrub native to the U.S. Southwest that contains natural rubber within its cellular structure.

Cooper and Goodyear participate in a consortium known as the Program of Excellence in Natural Rubber Alternatives (PENRA) with several partners, including The Ohio State University, to investigate the potential of alternate rubber plants including Taraxacum kok-saghyz, a type of Russian dandelion, as a domestic natural rubber source. 

Continental is working with the Fraunhofer Institute for Molecular Biology and Applied Ecology, Julius Kuehn-Institute and EKUSA, to produce, test and develop tires with tread made from 100% dandelion-derived rubber.

Bridgestone is shifting toward more sustainable mobility solutions by replacing petroleum in Firestone Ag tires with renewable soybean oil. Today, various percentages of soybean oil are in the Ag tires produced in the Bridgestone Des Moines, Iowa plant.

Goodyear’s breakthrough in applying soybean oil in the tread compound of tires as a replacement for traditional petroleum oil was commercialized in its Assurance WeatherReady™ consumer tire line in 2017, the Eagle Enforcer All Weather police tire in 2018, and the Eagle Exhilarate in 2019. 

Goodyear and Pirelli use silica derived from rice husks, which are inedible and might otherwise be thrown away, to produce tires with improved rolling efficiency. 

Hankook utilizes vegetable oil resin extracted from conifers to manufacture tires specifically designed for electric vehicles. The Hankook Kinergy AS EV tire, made with vegetable oil resin, provides electric vehicles improved wet road performance as well as general handling and braking.

Michelin and Bridgestone incorporate ground rubber derived from used tires as a closed-loop sustainable compound to produce new high-performance tires and tires for agricultural and off-road applications.

USTMA members strive to manufacture tires that reduce greenhouse gas emissions throughout a tire’s useful life.

Tire manufacturers recognize they play a role in reducing greenhouse gas (GHG) emissions, both by reducing manufacturing-related emissions including those from energy production and by designing tires with greater rolling efficiency, which improves fuel economy. Reduced fuel consumption equates to reductions in vehicle emissions.

Rolling Efficiency

Rolling efficiency measures the energy required to maintain forward movement. Improved rolling efficiency is the primary way tires in use contribute to reducing CO2 emissions through improved vehicle fuel economy. Low rolling resistance tires are tires with improved rolling efficiency, one of many factors that can improve vehicle fuel economy.

Improvements in modern tire materials, including the introduction of silica, have revolutionized the tire industry, drastically reducing older and less efficient compound materials and manufacturing methods. Today’s modern tire is a highly engineered marvel that delivers greater fuel economy while also maximizing safety, performance, handling and durability.

Rolling efficiency doesn’t just lower GHG emissions, it can also increase your bank account! A 10% improvement in rolling efficiency, for instance, can reduce consumer fuel costs by up to $36 a year (assuming fuel is $3 a gallon). Considering the U.S. Department of Transportation’s estimate of 263 million vehicles on American roads, that may mean more than 1.5 billion fewer gallons of gas are used for a total cost savings of nearly $9.5 billion.

Today, roughly 56 million scrap tires are contained in stockpiles, down from almost 1 billion in 1990. USTMA continues to work with state legislators and regulators on programs to help eliminate stockpiles.

The bulk of the remaining stockpiles are concentrated in eight states:

  • Arizona*
  • Colorado*
  • Michigan*
  • New Jersey
  • New Mexico
  • Texas
  • Virginia
  • Washington*

*have ongoing abatement programs
