Tomorrow’s market leaders will be the tire manufacturers who are able to overcome the challenges of long-term in-use tire performance while optimizing the costs. To accomplish this, it’s important to design a tire, therefore its innerliner, that maintains proper inflation pressure utilizing materials that demonstrate proven air retention performance.
Precious pressure. While driving a car, optimal pressure of the tires is crucial for ensuring the traveler’s safety and improved tire life. For the end users, tire life is important as it leads to lower cost-per-mile driven and less tire maintenance. What’s more, keeping the tire’s pressure at its best state leads to consistent in-use rolling resistance. This is valid for both Internal Combustion Engine (ICE) vehicles and EVs, respectively to mitigate fuel consumption and therefore CO2 emissions and enable longer vehicle battery range.
With the right halobutyl grade, the tire air retention of your vehicle will be improved, making a substantive enhancement in in-use rolling resistance - which remains consistent - durability and overall tire performance.
Better tire performance starts with optimal innerliner air retention. Conventional innerliner compounds include bromobutyl and chlorobutyl polymers. By designing effective innerliner systems, air loss and therefore “in-use” rolling resistance, can be minimized. This allows for better fuel efficiency - which is directly connected with CO2 emissions – and longer lasting battery range to be achieved.

Exxon™ butyl rubber (IIR) ensures excellent air-barrier, weathering resistance, aging resistance, vibration damping and good compression set.
Exxon™ chlorobutyl rubber (CIIR) provides an improved compression set and better resistance to heat, ozone and flex fatigue compared with regular butyl rubber, while maintaining the same excellent air-barrier properties.
Exxon™ bromobutyl rubber (BIIR) provides faster and more stable cure through additional carbon-carbon cross-linking compared with regular butyl rubber, while maintaining the same excellent air-barrier properties.
Electric vehicles with underinflated tires lose battery range, so retaining air is key. Learn about an existing easy solution, powered by Exxon™ halobutyl rubber.
Not all tires keep air inside in the same way. Learn more about how tires with Exxon™ halobutyl innerliners maintain proper tire pressure, and better air retention brings consistent performance.
