Tire
* All tires lose air over time.
* Most tire wear particles in the environment end up in surface waters
  - tires have friction
* Some tires conduct electricity
  - have a variation in stiffness that can cause a vibration
  - provide centripetal forces
* are THE control of a vehicle.
* are a common place for mosquitoes to breed
  - prime habitat for mosquitoes to breed
  - very precisely engineered product designed for specific applications and use
  - basically petro-chemical products
  - black
  - circulars
  - difficult to landfill because of their size and shape
  - electrical insulators
  - flexible and move toward the surface
  - good enough conductors to allow electrical charge to escape to ground
  - highly complex engineered products
  - hoops
  - life limited as the rubber ages and deteriorates with time
* are located in airports
  - cars
  - garages
  - repair shops
  - trucks
  - trunks
* are made of different types of rubber
* are part of automobiles
  - the most important safety item on a car
  - very flammable and emit toxic fumes and liquid by-products if they catch fire
  - wheels
* bleed air over time, often becoming flat by the spring.
* burning at landfills generate huge amounts of noxious air pollution.
* can make a big difference in how a car behaves
  - provide breeding grounds for mosquitoes and vermin when stored
* cause tires.
* come in many different sizes, widths and tread patterns.
* contain less ash than most types of coal and less sulfur than bituminous coals.
* deform, adding to their friction.
* depend on good tread condition to maintain traction and to shed water on wet roads.
* deteriorate over time.
* develop wear patterns as they age.
* do have a shelf life.
* emit toxic smoke when burned.
* features Describe the basic construction features of tires.
* fill with air.
* get extremely hot when burned.
* have effects
  - infinite friction
  - little effects
  - round shapes
  - spots
* includes sections.
* leave marks as a result of movement during a collision.
* lose air normally through the process of permeation
  - pressure naturally through the process of permeation
* play a major part in any vehicle's handling.
* provide protection.
* suffer from sunlight, ozone, and aging deterioration.
* wear differently over time, depending on which corner of the car the tire is on
  - particulate matter is generated by the movement of motor vehicles on the road
+ Tire, Construction: Auto parts :: Polymers
  * Tires are made of different types of rubber. Softer rubber is used in summer or when the tires need better traction, for example, in auto racing. Tires made of harder rubber are made for long lasting performance, like long-distance truck carriers. There are many different types of tires. They come in different sizes and have different tread patterns.

### tire:

Bike tire
* are more susceptible to flats than car treads.
* wear out just like automobile tires, only faster.

Car tire
* Most car tires fill with air
  - have two body plies
* Some car tires conduct electricity.
* are auto parts
  - automotive products
* pose a hazard when they end up in the landfill because they trap gases.

Old tire
* are a low cost material often used.
* are located in garages
  - one of the most common mosquito breeding sites
* laying in yards are a significant breeding site for mosquitoes.

Overinflated tire
* cause poor handling and uneven wear.
* have smaller footprints and produce less traction.

Radial tire
* are heavier than bias-ply tires of equal size, partly because of higher lugs
  - the traditional tires found on most cars
* rely on steel belts for strength.

### tire | radial:

Radial keratotomy
* form of incisional refractive surgery.
* is eye surgery
  - used to treat nearsightedness and some forms of astigmatism

### tire | rubber tire:

Retread
* are car tires.
