Okay Guys anybody have any ideas about what to do with old tires? I really dont want OCD,but I would like good ideas from an economic standpoint,that would handle most of the problem-Kevin ---

Well I think they do,but I’m never around when that happens,actually I think they accept tires at the transfer station(they actually need a certain amount to meet a recycling quota I believe)doesnt really bother me to pay a reasonable disposal fee. But hear this, when you could leave tires with abandon at a largely unmonitored transfer site,there was this cat who would dipose of tires from a neighboring county(they had a disposal fee) He would bring them when no one was around and dump them at our site and make money doing it,so I guess He spoiled it for everyone. Well from what I have been reading,the old tires make cleaner boiler fuel then coal,so whats not to like?I guess thats were OCD comes in on the Green Folks behalf.Dont get me wrong,I’m all for clean and green,but when there is a good solution that dont quite fit some Folks ideas of how it should be done,I look askance-Kevin ---

Tires here are just turned into the local recycling operation for $1-2 each. Then they are sold, ground up, recycled, used for fuel, roads, etc. That’s someone else’s problem. Don’t leave old tires laying around though. The water collects in them and is a perfect haven for disease carrying mosquittos. Get rid of them or drill holes in them to drain the water. ---

Thanks Fellas,I believe part of the the problem with old tires is they are a type of thermosetting plastic and you have to break the bonds of vulcanization to remold the rubber’ Anyway,I want to ask again,where are my tweels?-Kevin ---

Kevin, FYI, tire rubber is permanently chemically “cured”, so there is no way to “remold” it. It can only be ground up into “crumbs” for use in roads, etc, or burned for fuel. ---

@kevin, here’s a summary of how tires are made: > **[Tire manufacturing](https://en.wikipedia.org/wiki/Tire_manufacturing)** > > Pneumatic tires are manufactured according to relatively standardized processes and machinery, in around 455 tire factories in the world. With over 1 billion tires manufactured worldwide annually, the tire industry is the major consumer of natural rubber. Tire factories start with bulk raw materials such as synthetic rubber (60% -70% of total rubber in the tire industry), carbon black, and chemicals and produce numerous specialized components that are assembled and cured. This article de The tire... @keith corrected my incorrect terminology earlier. Tires are made by a “thermosetting” polymerization of polybutadiene in combination with other materials. > **[Thermosetting polymer](https://en.wikipedia.org/wiki/Thermosetting_polymer)** > > A thermosetting plastic, also called a thermoset, is a plastic that is irreversibly cured from a soft solid or viscous liquid prepolymer or resin. The process of curing changes the resin into an infusible, insoluble polymer network, and is induced by the action of heat or suitable radiation often under high pressure, or by mixing with a catalyst. Thermoset resins are usually malleable or liquid prior to curing, and are often designed to be molded into their final shape, or used as adhesives. Othe... The resulting rubber compound breaks down under heat so it can’t be melted and reformed, as opposed to a thermoplastic which can: > **[Thermoplastic](https://en.wikipedia.org/wiki/Thermoplastic)** > > A thermoplastic, or thermosoftening plastic, is a plastic material, a polymer, that becomes pliable or moldable above a specific temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The polymer chains associate through intermolecular forces, which weaken rapidly with increased temperature, yielding a viscous liquid. Thus, thermoplastics may be reshaped by heating and are typically used to produce parts by various polymer processing techniques such as injectio... The last paragraph here describes why tire rubber can’t be “unvulcanized:” > **[Vulcanization](https://en.wikipedia.org/wiki/Vulcanization)** > > Vulcanization or vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials by the addition of sulfur or other equivalent curatives or accelerators. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains. Vulcanized materials are less sticky and have superior mechanical properties. The term vulcanized fiber refers to cellulose that has been treated in a zinc chloride solution to cross-li Although... On a side note, many solid rocket propellants use a tire rubber component (hydroxyl terminated polybutadiene, or HTPB) as a binder/fuel in combination with an oxidizer like ammonium perchlorate. The resulting compound has the consistency of a pencil eraser and burns vigorously. ---

And to think that when I was a little kid in the early 60s the old tires were used to get the brush piles burning good. My dad would get permission from someone to cut firewood along a river during the winter when the ice was thick. We’d drag all the brush to the middle of the river and throw an old tire on the pile…douse it with deisel and lite er up. And you saved all the drain oil in a 5 gallon bucket. When the gravel driveway got too dusty in the hot summer, you would carry the bucket down the driveway and using an empty large coffee can…with holes punched in the bottom…you would sprinkle the oil on the driveway. It never dawned on us in the 50s and 60s that we were poluting. It was just one of those things that you did to maintain the place…just like having a burn barrel!!! ---

Yeah we used to dump the used oil on the driveway too, and of course buried the dead cats and fish in the ground too. I think you need a permit for that now so maybe they’ll come and dig my dog up. ---

Talk about hazards, they used to use dioxin to control road dust! I seem to recall they used it in the north woods of MN for the same purpose decades ago, looking for verification. “The children of Times Beach loved sliding around in Bliss’ purple-tinted goo, and no one gave the substance a second thought until animals (particularly horses, who had contact with Bliss-sprayed roads and barn floors and riding rings every day, all year round) started dropping dead. Soon people started to get sick, too. In 1979, the EPA came to town and took soil samples, and in 1982 the agency announced that the levels of dioxin–“the most potent cancer-causing agent made by man,” the newspaper said–in Times Beach were off the charts. The agency evacuated the town just after Christmas. In all, the agency spent $250 million and incinerated 265,000 tons of dioxin-tainted soil.” ---

@kevin, Shuttle solid boosters used PBAN polymer as a fuel, similar to HTPB. Yes, powdered aluminum was also a component of the propellant. But the exhaust wasn’t really toxic. Aluminum oxide is harmless. > **[Polybutadiene acrylonitrile](https://en.wikipedia.org/wiki/Polybutadiene_acrylonitrile)** > > Polybutadiene acrylonitrile (PBAN) copolymer, also noted as polybutadiene—acrylic acid—acrylonitrile terpolymer is a copolymer compound used most frequently as a rocket propellant. This was the binder formulation widely used on the 1960s-1970s big boosters (e.g., Titan III and Space Shuttle SRBs). It is also sometimes used by amateurs due to simplicity, very low cost, and lower toxicity than the more common hydroxyl-terminated polybutadiene (HTPB).
