    Armorall on your bike tires

    Yesterday when doing some routine maintenance on my bike, I noticed the sidewalls on my rear tire beginning to crack. It's getting pretty worn, so it's going to get down to the casing fairly soon anyway, but I was pretty surprised to see this since it's a good tire and not all that old. Anyhow, what I'm wondering is if using something like Armorall on your bike tires will help preven this sort of thing from happening, or at least delay it a bit. Now that I've learned to ride in such a way that I'm not skidding through a rear tire every six weeks, I'd like to keep them from disintegrating in the sun while locked up outside at work.

    Thoughts?

    I wouldn't do it. Bicycle contact patches are already small, and adding what is effectively a lubricant to that surface seems ill advised, at least if you value your skin over your skinwalls...

    I have wiped my sidewalls with Armorall with no adverse reactions. Be carefull not to get on your braking surface on the rims though.

    Me, I'm moe concerned with have no brakes than with a contact patch as the tire will scuff itself off in a few revolutions when on a nasty road surface.

    I'd be concerned however if I tried riding around on a linoleum floor. That's one of those "kids don't try this at home" things.

    it'd just be going on the sidewalls, rather than the whole tire. No point in putting it on the tread.

    The problem with most of those sidewall cleaning products is that they'll tend to migrate out to the tire surface anyway

    are your tires inflated enough?

    Sometimes if you do not inflate your tires enough your sidewalls will crack quickly.

    Be careful about using armor-all. I work in the automotive industry, and we use it to test materials for environmental stress crack (chemical+heat and/or time+flexing or stress=cracking and fracture). It has some pretty powerful ingredients in it that weaken a lot of stuff.

    Probably buying a product that is a tire conditioner would be safer and yield better results.

    I'll check that out. Any products in particular spring to mind? I just figure there's got to be something to help keep your sidewalls from cracking.

    any product that is intended for tires only... mothers makes one, eagleone does also. armorall is notorious for being really ****ty. i'd be a little worried about using that though, on car tires its usually safe because the tire construction is completely different (no rounded profile).

    silicone is a really excellent lubricant, and really hard to get off once it's on. Armorall and WD-40 are both high in silicone. would you put WD-40 on your tires?

    Incidentally silicone is verboten in paint shops, because once silicone gets on a surface, paint won't stick. You can't even sand it off. It makes a big mess. don't use Armorall anywhere near any metal surface you think may need paint work in the next 6 months. and I certainly wouldn't get it anywhere near bicycle or motorcycle tires. like not even in the same room.

    There os a product somewhere for treating bicycle sidewalls. It's pretty old school, but I know I've seen it somewhere. as far as I'm concerned when skinwalls start to get dried out, they aren't long for this world.

    Alright, Armorall = definite no. This is why I ask about things like this before I try them.

    Let the Armor All bashing begin.

    If you search the internet newsgroups (ie google groups) you can find a lot of armor all discussion in rec.autos.tech. One excellent post that illuminates the nature of how armor all works goes as follows:

    "OK, if you want a detailed chemical explanation, here goes.
    Soft vinyl plastics (as opposed to things like PVC pipe)
    contain a large amount of plasticizers. The one that is
    almost universally used is dioctyl phthalate. It is a
    relatively high molecular weight, water insoluble, nontoxic
    compound. Over the course of time, the plasticizer will
    vaporize and leach out of the vinyl causing it to become
    stiff and brittle, which is when it cracks.

    ArmorAll is an emulsion of dibutyl phthalate in water.
    Dibutyl phthalate has a lower molecular weight than the
    dioctyl phthalate in the factory soft vinyl. While it will
    plump up and soften the plastic (good) the lower molecular
    weight means that it is more volatile and more water soluble.
    Therefore it will be lost more quickly to the environment
    via vaporization and leaching. A nasty side effect is that
    it will take the original plasticizer with it as it is lost.

    What this means to the end user is that if you start using
    ArmorAll you had better continue to do so, or your vinyl
    will degrade much faster than if you had done nothing. "
    http://groups.google.com/group/rec.a...a81025475ac008

    Now, I understand that vinyl is a very different material than rubber, but I think the same idea applies. I'm guessing it will make rubber dry out faster unless you continue to use it regularly.

    i thought my sidewalls were cracking from over-inflation. under-inflation does it too?

    Armor will actually cause your tires to crack if you don't use it religiously. If you are near any higher end car accessesory shops, look for either zymol or einzeitt (1z). They are both kinda pricey, but really good tire conditioners.
    I'd rather have a bottle in front of me than a frontal lobotomy.

    If your sidewalls are cracking, then its time to get new tires.

    The point being that they're cracking earlier than they seem like they should. It doesn't seem unreasonable to ask that a bike tire go six months without starting to crack, you know?
