The summer tire for SUVs and crossovers Goodyear EfficientGrip SUV is characterized by a number of key features, some of which significantly limit its scope of application, while others advantageously distinguish it from most similar tires from competing brands. This model is designed for use primarily on paved roads, where it demonstrates its most significant advantages. Most of them are the result of the use of FuelSaving Technology in its design. It, in turn, represents a complex of technical solutions aimed at achieving maximum fuel efficiency and extended tire life. To a greater or lesser extent, they affected all components of its design, from the carcass to the tread compound and its design.
Lightweight carcass
The basis of the design of this model is a carcass that, taking into account the above-mentioned characteristic features, differs in reduced weight. The savings were achieved due to the wider use of synthetic materials. Moreover, the carcass is made entirely of them. At the same time, the number of cord layers was reduced, as was the thickness of the sidewalls. In combination with the use of "seamless" winding technology, this made it possible to reduce the weight of the tire by more than 10%.
The heat generation and rolling resistance changed accordingly, which had a positive effect on fuel efficiency.
Shorter braking distance on dry and wet roads
Another "point" that was given maximum attention during the development of this model is ensuring maximum efficiency when braking. To do this, it was necessary to use several technical solutions that affected both the tread design and the composition of its rubber compound.
The shoulder areas of the tread contain many wide crosswise blocks, each with several straight lamellas cut into them. At the same time, they are connected by a thin longitudinal rib, which provides a rigid connection between them. During movement, the blocks and the lamellas cut into them form many transverse edges of adhesion. The connecting longitudinal rib and the massive size of the blocks themselves give the adhesion properties stability and reliability, which significantly reduces the braking distance. In turn, the tread compound "helps" to slow down more effectively due to special polymeric compounds that provide its more dense contact with the road surface.
Long service life
The tread compound has no less significant influence on the duration of its service life. The above-mentioned polymeric compounds at the molecular level increase its resistance to breakage. On the one hand, this improves the durability of the tread to any type of wear, and on the other hand, it ensures its integrity when driving at high speeds and high-temperature effects.
Another important factor determining the long service life of the tread of this tire is the design of its pattern. All its elements are arranged in such a way and have such sizes and shapes that ensure the most uniform distribution of the load over the contact patch. This feature significantly reduces the likelihood of premature wear of the tread.
Easy vehicle handling
A characteristic feature of the tread of this tire is that all five longitudinal ribs it contains have a solid, uninterrupted structure. This gives them excellent resistance to deformation. The constancy of the forms and sizes of these tread elements provides the Goodyear EfficientGrip SUV tire with a number of important advantages. The main one is the speed and accuracy of its reactions to steering wheel turns. In combination with stable and very stable behavior at high speeds, this creates a feeling of ease of handling for the driver, which, thanks to such a design, demonstrates very fast and accurate reactions to his actions.
Main features of the Goodyear EfficientGrip SUV tire
