Tire siping is the “secret sauce” to take your tire performance to a higher level at a very minimal cost. Here’s a simple explanation of the process and benefits of siping

The tread surface on your tire is made up of many smaller surfaces known as “Tread Blocks”. The reason for so many surfaces is especially important when it comes to icy or wet road conditions. The Tread Blocks get their gripping power not from their many smooth surfaces but from the even more numerous sharp surrounding edges. Siping improves the job started by your tire manufacturer by providing more of these gripping edge
Siping extends the window allowed for maximum braking power by giving the existing tread a helping hand. Take a close look at the photo above and notice how the Siped tire has dozens more gripping edges.
Siping gives your tires Micro-Flexibility reducing the wear on your tire’s carcass and sidewalls. This effect not only increases tire life, but will result in a smoother ride.
Heat generation is a common cause of rapid tire wear and even tire failure at times. While heat may be a natural result of friction, the effect it has on your tire can be undesirable. Siping reduces the heat and its effect on your tire by allowing it to cool. Much like your cars radiator, heat is isolated into small groups and air passes between these areas triggering a natural cooling effect.
Siping is done by placing your tires (new or used) on a specially designed machine that rotates your tires while making small virtually invisible 90 degree cuts in your tread. Although the process is actually cutting your tread – don’t be alarmed, it does not hurt your tire in any way, it improves on it. Only under very close inspection can the Sipes even be seen, and you’re more than likely to tell by your improved driving experience than by visual inspection. Siping will not adversely affect your tire’s performance in any way. The tread on your tires retains all of its strength due to the patented spiral cutting process. This process leaves uncut areas known as Tie Bars – keeping your tread strong.
