The summer tire Yokohama Y870 is a specialized tire designed exclusively for use as a "spare". The model is focused on simplicity, minimalism, and low cost, offering stable traction on dry and wet surfaces at speeds up to 80 km/h.
The tire's tread stands out with a narrower width than standard tires. It has a sufficiently developed pattern with a large number of elements. First and foremost, these are longitudinal grooves, which, due to their increased size, effectively prevent the formation of a continuous water film between the tire and the road surface. An important feature of the tread pattern is the presence of massive blocks along its edges. These elements provide more stable traction when maneuvering, increasing the accuracy of control in such conditions. Another notable difference is the tire's carcass. It is a multi-layer synthetic cord that uses progressive winding technology - the fibers are arranged in a spiral, without any joints or seams. As a result, the carcass is characterized by extremely low weight, combined with high stiffness and resistance to deforming influences, which positively affects both the reliability of the tire and its resource. Other important features include the tread profile. It has an optimized shape, which significantly increases the size of the zone directly contacting the road surface. This substantially improves the traction properties, both when driving in a straight line and when maneuvering.
Key features of Yokohama Y870:
- enlarged drainage grooves provide reliable traction on wet surfaces;
- optimized carcass with spiral cord winding is characterized by low weight and increased stiffness, reducing rolling resistance and tire mass, improving traction stability;
- special shape of the tread profile increases the tire's contact patch with the road surface, providing improved driving characteristics.
