As the only link between the car and the road the tire plays a key role in the overall performance of the car to offer a worry-free ride.
A number of our research work and technologies focus on optimizing the tire performances in all kind of conditions as external parameters such as road and weather conditions can influence the overall performance of a tire.
Winter tire technology
Driving in winter conditions can be quite challenging. This is why we develop winter tires tires that help drivers to maintain control in adverse weather conditions, when grip can be reduced, and sometimes can feel non-existent. A winter tire has to perform efficiently in all conditions, from a dry road to an icy surface. Winter tire technology not only enhances road safety and mobility in snow and ice but also enables vehicles to perform better in handling, braking, cornering and accelerating in cold weather conditions when temperatures fall below 7ᵒC.
As one of the leaders in winter tire development, Goodyear and Dunlop introduce new winter tires every 2 to 3 years and the development process includes:
- distinctive tread design including special grooves and multi-dimensional sipes
- types and composition of the tread
- softer and more flexible polymer compounds
- special sipe technology
- shape of the contact patch:
For summer driving and warmer temperatures the use of standard tires is recommended, as they offer the optimal performance on dry and wet roads under these conditions.
Goodyear's Air Maintenance Technology (AMT)
The correct tire pressure is key for the tire to perform at its best and contributes fuel efficiency, reduced emission, increased mileage and handling of the vehicle.
The Air Maintenance Technology (AMT) of Goodyear consists of a self-inflating tire system, this means it conserves the correct tire pressure within the tire without any help of external pumps, electronics or intervention of the driver.
SoundComfort : Foam in Tire technology
A rolling tire generates some of the noise that is heard inside the vehicle. A very specific tire-noise is “cavity resonance.”
The air inside the tire can be compared with the air inside an organ pipe. The air starts to vibrate when it’s activated…in the case of a tire, the activation happens through irregularities roughness when the tire is rolling down the road. This vibration is transmitted into the vehicle and is heard as a noise.
By attaching a strip of foam to inside of the tire we can reduce the noise intensity by a factor 2 inside the vehicle, without having any impact on other key performances of the tire. This represents a very significant improvement of the overall comfort level inside the vehicle, especially for EVs and high end hybrid cars.
Radio-Frequency Identification (RFID) Technology
RFID technology allows each tire to be quickly identified, offering commercial fleet owners time savings.
The technology consists of a built-in small chip for truck tires that communicates with Goodyear’s online tire management interface, FleetOnlineSolutions with the help of a specialized scanner that gathers and registers the tire information accurately far more efficiently than done manually.
