    i have 39.5x15x15 TSLs and am considering siping them. A local shop does it cheap. Question: will siping help with off-road performace in any way? these tires never see asphault... so I aint worried about on-road benefits... Im interested to know if its a good thing for offroad stuff. any thoughts/input would be appreciated. /forums/images/graemlins/laugh.gif

    siping lets the tire carcass flex more... more footprint...

    <font color="green"> Be aware that when shops do the siping they use a machine, which will make the sipes real close to the edges of the lugs so you'll end up chunking the edges of the lugs off. It's a better idea to do it by hand and keep the sipes at least 1/2" from the edges of the lugs, and only do the middle ones.</font>

    I've siped all my swampers with a carpet knife, seems to help out noise and wear and ride wise, but I know for a fact it sure helps on the ice

    I hand siped my Q78's and really liked it. Better traction in most situations, especially we slick rocks, snow and ice, and even some increase in bite on dry rock. I'd do my 42's now but don't have the right iron anymore. Figures, we get the kick butt groovin iron and it still won't do everything I want.

    definitely do it by hand, the machine can't do it right.

    <font color="green"> The width can be set, but it still just rolls them on so on alot of the lugs you'll end up with sipes real close to the edges. </font>

    I have had two sets siped. It does'nt help wear or melting of the rubber on road but it sure helps in rain and ice. When I do it again I will not go all the way to the edge because it does chunk the lugs real easy. Like others have said. I only get three years out of my TSL's but they are on the highway all the time. I drove from Alaska to Georgia and covered all types of terrain, I will do it again. /forums/images/graemlins/burb.gif

    I was under the impression that there were TWO different tecniques: Siping and Grooving:


    Siping: cutting across the tread using a very thin blade (and not removing any material) to create small slices that give better bite in snow/ice conditions. IIRC, this can also help make the tire somewhat quieter on the road. It does nothing to improve tire carcass flex, since it does not remove rubber.

    Grooving: The process of removing significant amounts of rubber from the treadblocks to make them smaller and more flexible. This has the effect of allowing the tire carcass to "wrap around" rocks when aired down, and provided better traction. IIRC, this creates more heat in the tire on the highway, and makes it noisier since there are now more "voids" to resonate???


    Anyway, just thought I'd compare my "memory" with reality! /forums/images/graemlins/grin.gif

    ResJoe, Carpet knife?? /forums/images/graemlins/confused.gif
    Can you shed some light on this for an ignoramoose like me?
    I'd like to add siping to my tires but don't want to spend big $$$, or even small$$$ for that matter, on a grooving iron that in my claws might make my tires worse than before.
    thanx

    1. Take a carpet knife

    2. Cut lines however you want at nominal depth all over the tread

    3. Get hand cramps

    EASY!!!

    It's really hard to cut TOO deep unless you want to spend 10 seconds a cut (400-1200 cuts total!), I usually end up goes WHAKC WHACK WAHCK randomly

    Here's Some Pics

    Use a dremel cut off disc, the sipes would be a little bit wider but it would be so easy to do.

    Id think those little discs would break, they're picky lil sumbitches

    I know of a guy who did grooving with a circular saw /forums/images/graemlins/shocked.gif

    For the outer lugs you could do the sawzall thing or the welder thing

    I'm gonna try the welder thing someday when I'm bored

    Good luck everyone
