Goodyear’s own test results show that its new EfficientGrip summer tire provides 15% lower rolling resistance.

Tire manufacturer Goodyear introduced a new high-performance summer tire at the Geneva Motor Show. The tire is said to offer lower fuel consumption, long service life, and good wet braking performance.

Goodyear’s own test results show that the new tire provides 15% lower rolling resistance, braking distances reduced by 3% in the wet, and 3% better wet handling characteristics. The company claims that the tire will also offer up to 25% greater mileage.

The EfficientGrip tire incorporates Goodyear FuelSaving Technology, which consists of a number of developments that reduce the tire’s rolling resistance. These include a lightweight structure, reduced heat generation, advanced compound materials, and new manufacturing techniques.

Goodyear reports weight reductions of around 10% for the tire compared with its predecessor. EfficientGrip features a lower polyester ply end and less material in the sidewall. Lower heat regeneration results from Goodyear’s patented CoolCushion Layer. This involves the use of a new thermoplastic ingredient used as a reinforcing agent, which is a partial substitute for carbon black.

EfficientGrip compounds are produced using the latest generation of polymers. These feature improved energy dissipation characteristics, helping to reduce rolling resistance. The tread pattern includes a set of four wide grooves around the circumference. The shape and position of these are said to deliver better water dispersal characteristics and reduce the possibility of aquaplaning.

To date, Renault has specified the new tire as original equipment for the Megane 3, and Mercedes-Benz has specified it for the E-Class. EfficientGrip is available in a range of sizes from 14- to 18-in diameter.
