Yokohama has just launched two new tires. We’ve talked about it on Blackcircles.ca. But like all journalists in the world, I’d like to believe the manufacturers … but I also like to put things to the test myself.
The next few weeks will see an extended test of Yokohama ICEGUARD G075 winter tires, new tires unveiled and designed for SUVs around the world. A major part of market, considering that over 72% of new vehicle sales in Canada are light trucks and sport utility vehicles.
In my case, the test will be done behind the wheel of a Dodge Durango, a little more than 10 years old. It is a utility vehicle in the purest sense of the term, since it is used mainly for the transportation of goods and passengers. But when the dimensions require it. In other words, it dates a little, has a flawless mechanics, a body a little less spectacular, but has the precise mission to act as a practical and versatile vehicle.
The winter test will be even more demanding, since not only is the vehicle used extensively in the streets of the city. But it circulates a lot, fully loaded, in the country roads where snow removal is more randomly completed.
YOKOHAMA ICEGUARD G075
But why the G075? Because Yokohama promises that they are significantly better than the older versions of winter tires. Of course, the sole pattern of the G075 is designed to ensure good circulation in heavy snow, clearing collected flakes and slush. Lateral grooves also bring out more water, providing better grip on ice.
This better circulation is possible because of the new directional sculpture that increases the contact area and optimizes the edge effect on icy / snowy surfaces. The tread pattern has zigzag-shaped main and intermediate grooves, a broad center band, micro diagonal grooves, and triple-sided 3D sipes. In a few words, the layout of the soles allows for improved evacuation.
Two other elements also distinguish this tire: the rubber compound, of greater density, ensures a greater rigidity of the rubber blocks of the tire, guaranteeing once again a better contact with the road. And the fact that this compound diffuses heat better, which gives a lower rolling resistance.
Obviously, these last explanations come directly from the manufacturer. It will be necessary to wait a few weeks, when the snow seriously hits our roads, to confirm this ourselves.
