sipping tool(hot knife) you can buy for at least for $200.00 w. 2-3 different blades. i did my tsl years ago. & loved them. they were used for rock crawling.
i dont think sipping the tires will make them last longer. it will shorten the life even driving on the road. |

| I just want to do it so I don't have to buy tires for the winter as the truck is pretty much my daily driver |

2500guy - about 10 years ago, we did a tech article (actually, it was our first, believe it or not) on siping tires. We had all tires siped on both an '87 Blazer and a '77 CJ5.
See article: http://www.4x4review.com/tech/siping.asp
We found that tires did indeed last about 25% longer (which included a lot of street use, lots of hard-core off-roading, trail usage, etc.). When we were rock crawling, we really felt that we got a good amount more traction too.
We compared the differences between similar vehicles in many areas, and found that the claims for siping tires were indeed true.
You don't see a lot of shops siping tires, unfortunately. This is probably because many tires come siped from the factory already. The TSL SSR tires became so famous because of their siping.
The other benefits we saw were increased traction on wet roads. We weren't able to test our siped tires in the snow or ice, because we were testing in Arizona, but in speaking with other people, it does help a lot.
The article explains why, how, etc.
Hope that helps.

WOW!!!!!!!1 i would really think it would have more tire wear.
it did for me. my old blazer wa a trailer queen. i would lose lugs that were sipped due to traction(good traction). it would tear off lugz. |

It was probably siped too deeply then. A friend of mine did his own siping and made the grooves really deep. This screwed things up really bad and he'd have chunks come off of his tires. I don't know off of the top of my head how deep the sipes are supposed to be, but I think it's only about 1/4 to 3/8" deep.

basically when you sipe, you do not want it any deeper than main tread depth and actually a bit less. (sipes wear clean of before tread does) if you do it too deep, the lug can rip off. Proper way to do it too is with a hot knife not a cold one. |

That works fine for street tires and moderate "All Terrain" tires, but not for mud terrains or tires like TSL's, MT/R's, Boggers, etc.
The tread depth on those is 3/4 - 1" deep. When I sipe my tires, I go about 1/4" deep is all.

In that case I would go about 1/2 inch deep. 1/4 inch is too little for best effect here. |

Not for rockcrawling it isn't. For all-around stuff, I would agree - you need a more overall seperation effect.
With rockcrawling and hardcore trail running, you start ripping the lugs apart (sheepishly, I've been there, done that). ;) |

2500guy - call a few tire stores and see if they sipe. If they don't, ask them who in town does.
It's often pretty cheap, as they don't have to break down the tires. Sipe the whole darn tire (from edge to edge)... don't just sipe the middle.

| Of course you could stud your mud snows too like I do and skip the siping. I run 4 studded bias plied truck type mud snows on my plow trucks in winter. They are awesome. |

| Check your local laws about stud tires though first... Last I heard, you can't write tickets off as a snow-plowing business expense. [:D] |

Studs are quite legal here 5 months a year (Nov 15 to Apr 15) and have been as long as I can remember |
