Tire siping

they also wear quicker so no one wants it.

 

I'm going to go with it being more profitable to sell you a tire. It seems like it's really only small outfits that groove tires for themselves.

 

Look at the michelin xdn2 drives. I run them in the winter great grip. Tread full of sipes

 

Cars and trucks are totally different animals. It also makes the tire softer and increases rolling resistance. It only takes a few minutes with Google to read the many articles.

Here is one of them

In 1923, a slaughterhouse worker named John Sipe took a sharp knife and cut a series of small slits in his rubber-soled shoes. Finding that these cuts in the rubber gave his shoes much better traction on wet slaughterhouse floors, he went down in history as the inventor of docksiders. And siping.

Some years later, Goodyear decided to try the same thing on their tires. Even though tires had grooves and channels to evacuate standing water from under the tread, there still remained a very thin and slick layer of water that interfered with sure grip. But when the tread blocks were cut with small sipes, the cuts opened up as the tread block flexed, creating an area of low pressure that sucked up that last tiny bit of water under the tread, allowing for much better grip. These “rain sipes” soon became a standard throughout the industry.

The next major advance in siping technology came from Nokian, which developed a zigzag siping pattern for winter tires. This “Hakka Sipe” allowed the tread block to flex much more than rain sipes, and created hundreds of angled biting edges that produced extraordinary grip in snow and ice. Nokian’s siping pattern was quickly copied onto nearly every winter tire in the world.

The disadvantage of siping patterns, however, lies in the fact that the denser the pattern of sipes that you cut into your tread blocks, the more they allow the blocks to flex, which leads to squishy handling and much faster wear. From this disadvantage has come the latest revolutionary advance in siping technology: 3-D Self-Locking Sipes.

Although known by many tiremaker trade names, all share the same basic concept. Three-dimensional sipes are cut with an internal topology designed to lock the sipes together and prevent too much flex. This allows for very dense siping patterns while keeping the tread blocks stiff for good handling and substantially reducing treadwear.

Wouldn't run a tire that wasn't siped
