The tread pattern of the MICHELIN Pilot Alpin 4 tire may differ from the one shown opposite. Depending on the size, the tread can be asymmetrical or directional.
Why do you use asymmetrical and directional tread patterns?
Indeed, the new MICHELIN Pilot Alpin 4 tire exists with 2 different tread patterns. MICHELIN worked simultaneously on these two solutions: the first was produced in collaboration with Porsche, the second in a more generic development. Both solutions have produced excellent results. Each of the tread patterns respects the "Ridge'n'Flex" philosophy and uses the same elements in slightly different combinations.
Traditionally, asymmetrical treads are perceived as offering better handling. What about the behavior offered by the MICHELIN Pilot Alpin 4 with directional tread?
Indeed, using an asymmetrical tread pattern is one solution to improve handling, but it is not the only one. As you know, a tire is a product with many elements. By combining them in different ways, you can obtain excellent behavior, whether the tread is asymmetrical or directional. One example is the new MICHELIN Pilot Alpin 4 directional tire approved by Porsche for its 911 and Boxster models.
Does this mean that the Michelin Pilot Alpin 4 directional tread tire is reserved for Porsche vehicles?
No, not only.
You might think so, because we started with sizes for Porsche vehicles, but we can make directional tread tires for other vehicles to better meet the demands of manufacturers.
Today these sizes are available in two versions: V and W (with or without specific marking for Porsche).
