    Siping Tires

    Found this article... anyone have any experience or advice with siping
    tires? Any bad side-effects?

    Personally I would not subject my tires to change from manufacturers specs.
    At minimum it could void the warranty.
    I'd buy the tires I need and forget about this.

    This is a phrase the Les Schwab Company has lived by for many years.... they
    are the ones who sold me these tires and they are the ones who sold me on
    siping the tires. I'm sure that if there were any problem at all, they
    would certainly guarantee what they sold me. I've heard no complaints
    about siping tires nor that siping voids any warranty.

    Michelin Arctic Alpins are already siped by the manufacturer.

    Here's a little pic of the process (via Google).

    Any decent snow tire will come siped from the manufacturer. If snow
    performance is important, I'd advise getting snow tires. I would always
    advise against siping all-season tires for use in the winter.

    Some might think they're going to save money, but I don't believe they will:
    By siping all-season tires you dramatically reduce the tread life of the
    tire. If this tire is then used year-round, it will need to be replaced
    much sooner, increasing long-term cost. If it is only used in the winter
    time, then you really haven't saved much money over buying dedicated snow
    tires.

    I'm don't think that siping all-season tires is necessarily dangerous in any
    way; I'm just not convinced that there's a practical reason to do it.

    they 
    I've seen discussions where it could void warranty. It may aid traction but
    I find it hard to believe that it would extend tire life and think it may do
    the opposite. Prices I've seen - ~$10/tire/year - would tend me to believe
    you would be better off to put this investment into original tires. One
    discussion group also said that need for siping was greater in the past when
    tires were not designed as well as they are today.

    If it does, I will go after the dealer who sold it to me.
     

    I absolutely agree that it seems far too good to be true... however
    everything I've read about siping says otherwise. It does make some sense
    that these slits help to keep the tire cooler, therefore less tread wear. I
    can't find anything that says otherwise.

     

    $11.50 each tire and no need to perform the siping every year, siping is
    good for the life of the tire from what they told me. Makes it unnecessary
    to switch out tires every year, so saves $$$.

     

    These Toyo ultra 800's I purchased last year had no siping. I'm guessing
    that siping is not done on many of the tires today because not everyone
    needs it... not everyone drives in icy conditions. I'm also guessing that
    siping would add to the cost of manufacturing a tire, so it probably makes
    marketing sense to just sell tires cheaper without the siping.

    All I really know for sure is that my OBW seems to be responding much better
    now in slippery conditions. Hope it stays this way for the life of the
    tires.

    I'm just speculating of course but heat problem in radial tires is in side
    wall due to constant flexing.
    Tread wear in tires is most rapid in the beginning because of low modulus
    rubber's friction on the road.
    Seems to me the slits would make the tread even more squirmy leading to
    higher wear.
    The tire folks used to screw you on the warranty by measuring treadwear as
    if it were linear and prorating refund on this basis.
    My Googling gave lots of discussion on siping but none by the actual tire
    companies so it is hard to make real judgements.
