Never heard of it...do you all think it works?

http://discounttire.com/dtc/brochure/tire/tireSiping.jsp

It does not mention if it is good for the life of the tire...although the illustrations give the indication that it does work.

Sorry if it is a repost.

Tire Siping


Discount Tire Co./America’s Tire Co. offers the revolutionary tire “Siping” procedure. Here's how siping works:

Siping Detail Saf-Tee® siping cuts slits, called sipes, at 90° angles across the tread, providing thousands of gripping edges for better traction and stopping power. Wear-robbing heat and hydroplaning are also minimized.

Check out the information below to find out how you can improve your traction in poor weather driving environments.

Improved Braking
Research has shown that the most effective braking power occurs immediately prior to losing traction. Siping extends the window allowed for maximum braking power by giving the existing tread a helping hand. In the examples below notice how the siped tire has dozens more gripping edges. These micro edges reduce the distance needed for braking on wet and icy roads.

Better Traction
The tread surface on your tire is made up of many smaller surfaces know 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 more numerous sharp surrounding edges. Siping improves the job started by your tire manufacturer by providing more of these gripping edges.

Smoother Ride
New asphalt is relatively smooth but time and wear exaggerates the coarse texture of the road's surface causing your tires to absorb most of the impact. Siping gives your tires a Micro-Flexibility reducing the wear on your tires' carcass and sidewalls. This effect not only increases tire life but will result in a smoother ride.

Scientific Tests Confirm It


Improved traction up to 200%! An independent company tested the siping effect on starting, stopping and driving traction while driving on medium snow pack.

Repeated tests proved that siping increased starting, stopping and driving traction by as much as 200%!

The Goodyear Eagle LS (all season tire), and the Michelin Pilot Sport (high performance tire), were chosen for testing. The traction of the industry-standard all-season tire (the Uniroyal Tiger Paw) was also measured to set a base amount for comparison.

The unsiped Goodyear Eagle LS traction measured 101% of the base tire; the siped Goodyear Eagle LS measured 134% of the traction of the base tire.

The unsiped Michelin Pilot Sport read only 35% of the base all-season tires' traction. Siped traction improved by 200% - surpassing the traction of the 'All Season Tire'.

For complete technical data regarding these tests, please visit http://www.sipers.com/sipers/siping_tests.asp.

How is Siping Done?
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. Don't be alarmed! Although the process is actually cutting your tread, it doesn't harm your tire in any way, it improves on it. Only under very close inspection can the sipes even be seen, and you're more likely to tell by your improved driving experience than by visual inspection.
Will Siping Adversely Affect My Tires Performance?
Siping will not adversely affect your tires 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.
Why Don't My Tires Come Siped From the Manufacturer?
Our siping process doesn't remove ANY rubber from the tread allowing the individual sipes to support each other. A molded sipe leaves vacant gaps in the tread. Siping creates edges without gaps. To sipe (in mass production) after the molding process would be too expensive and time consuming for the manufacturer.
Where Can I Get My Tires Siped?


Many of the Discount Tire Co./America's Tire Co. stores provide siping services. Contact a store near you to find the closest authorized siping center.

lemme ask you this...

if it's so great, why don't tire companies do it after spending millions on tread pattern development?

'Cause Discount Tire is smarter? :D Jking...I'm not that slick on these things, and I know it is a new thing for discount tire...just checking it out. I personally don't see how it would not affect the life of your tire.

The only benefit I could see, is that you could buy a cheap, hard tire, get that done and have a somewhat stickier tire cheap. I seem to recall people knicking up their tires at the Mason-Dixon drag strip....so I thought this might be a profession knicking job. haha

Take care,

It is not new from discount tire they have been doing it for at least 6 years now. Also lots of the high mileage tires come from the factory with siping. It only helps for traction in the rain and it is really good for tires that you use on a family four door car. It helps the tires not get so hot when on road trips and keeps them lasting longer. You dont want to use it on high performance tires. That is why they dont sipe the high performance tires. They slits will help squeegie (sp) out water when it is wet out side.

i bought my michellin tires from discount tire, for my tahoe, and they kept pointing out all of the "siping" or whatever...i was in too big of a hurry to fully listen to the crap that was rolling out of his mouth, though, so i just shook my head and drove off...all i remember was that he kept telling me how good they were because they had all of those little slits in the tread...it seems kind of cheesey, but who knows...

Yeah, actually some of the tires come with them already. Michelin tires have full depth sipes already. Meaning that when the tread gets low, the sipes are still there. Some only have 1/3 depth or 1/2 some have none. They actually do work.

sipes do work, like above, some brands come siped. however, it isn't anything id pay to get done. if you can find a way to get it done for free, sure go ahead. at work we actually got rid of our sipe machine because it just wasn't worth it.
