The road to safer, more energy-efficient “green” tires

In the 1990s, tire engineers discovered that if they used silane-treated silica instead of carbon black as a reinforcing filler in tread compounds, tire rolling resistance was reduced. The tires also gripped better on slippery roads.

Studies have shown that silica-reinforced “green” tires can reduce tire rolling resistance by up to 20 percent, which can reduce vehicle fuel requirements by as much as 5 percent. Widespread use of these green tires could save millions of barrels of oil per year and reduce carbon dioxide (CO2) emissions significantly.

Additionally, silica-reinforced tires are more resilient than traditional tires. This gives them better traction on wet and icy surfaces and can reduce stopping distances by as much as 15 percent, making the roads safer for everyone.

In the past, the cost to manufacture the silane coupling agents used to produce silica-reinforced tread compounds made these tires too costly for many consumers. However, a recent breakthrough in silane production technology is making the production of silica-reinforced green tires more affordable.
