[Rubber Innovation] Tires Will Now Have "Energy Labels"! 2026 Tire Efficiency and Fuel-Saving Tech
Just like home appliances, tires will soon require "energy efficiency ratings"! To improve fuel efficiency, reduce carbon emissions, and ensure driving safety, the Bureau of Standards, Metrology and Inspection (BSMI) has officially mandated: Starting July 1, 2026, all passenger car and light truck tires sold in the market must pass inspections and display a "Tire Energy Efficiency Rating."
Evaluating a tire's energy efficiency mainly depends on three key indicators:
-
Rolling Resistance: This is the friction between the tire and the road while rolling, accounting for about 15% to 30% of a vehicle's overall energy consumption. The lower the resistance, the more fuel or battery power is saved.
-
Wet Grip: The accident rate on wet roads is twice that on dry roads. Therefore, while reducing resistance, maintaining high wet grip is crucial for braking and driving safety.
-
Coasting Noise: When vehicle speed exceeds 60 km/h, the friction noise between the tires and the road often surpasses wind noise, making this an essential evaluation metric.
The Tech Behind the Scenes: Who Introduced the Resistance-Reducing Tech?
Facing stricter regulations, car manufacturers are urgently seeking solutions. At the Tire Technology Expo in Germany in March 2026, a breakthrough technology for "natural rubber" sparked intense discussions. Many wondered which tire brand produced this new product. In reality, the driving force behind this technology is the world-renowned specialty chemicals giant—Nouryon.
Nouryon unveiled a patented formula that, by adding a small amount of "novel organic peroxides" during the tire manufacturing process, alters the bonding structure of rubber and carbon black at the molecular level. This significantly reduces energy loss when the tire rolls (known in physics as the Payne effect). This raw material technology will be supplied to major tire manufacturers worldwide, helping them produce next-generation tires that comply with the new 2026 regulations and allow EVs to travel further!
[Editor MARS's View] Regulations Provide the Push, but Material Innovation is the Real Power!
Seeing that Taiwan will fully implement tire energy efficiency labeling in July 2026, Editor MARS believes this is an absolute cure-all for driving industry progress! In the past, people only cared about durability and price when buying tires. In the future, the market will compare whose tires save the most fuel and electricity.
This explains why international chemical giants like Nouryon are working tirelessly to develop new peroxide technologies. Global tire manufacturers are now desperate to find the secret weapon to "reduce rolling resistance." From the perspective of the rubber processing and recycling industry, once environmental regulations are enforced, upstream material formulas face a massive reshuffle. Whoever masters the chemical technology to make traditional natural rubber smarter and more energy-efficient will secure the largest orders in the future green supply chain!
