Every year, about 290 million tires are discarded; of those, about 233 million are recycled in one way or another. Shredded tires can be used for playground surfaces, welcome mats, hot-melt asphalt, bark mulch and even made into building material for “green” construction.
But what can you do with your old tires? Here are some ideas:
--Fill a tractor tire with sand to make a great sandbox for kids
--Hang a tire from a rope as a tire swing
--Stack a couple of tires on top of each other, bolt them together and paint them a cheerful color, then use them as a planter
--Lay two rows of tires next to each other, somewhat staggered, and use them for broken-field running as part of football conditioning
--Bolt two tires toget ...[more]
Ever think about all the different vehicles that use rubber tires? Tractors, industrial equipment, everything else that rolls on rubber?
Each specialized type of tire requires a specialized design for its specific purpose. Aircraft tires, for instance, have to be very robust and handle a great deal of weight and stress, but for only a short period of time. Aircraft tires are often filled with an inert gas such as nitrogen, for more stable inflation levels, and are designed with specialized fusible plugs which provide a safer failure mode (rather than a sudden, catastrophic tire explosion).
Off-the-road tires, for vehicles such as graders or mining equipment, operate at low speeds but have to be able to withstand severe service conditions while h ...[more]
You know that winter and bad weather are coming. Is your car ready? Here’s a quick checklist of things to get up to speed on:
Motor oil: Motor oil has a tendency to thicken in cold weather, making it harder to circulate to upper engine parts at startup. If you haven’t ever used synthetic oil before, this might be a good time to start. The flow properties of synthetic oil are a lot more consistent, meaning it doesn’t thicken in sub-freezing temperatures or thin out when it’s hot outside.
Wipers: Even the best windshield wipers only last about a year. If your wipers are showing cracks or chips or losing strips of rubber, go ahead and replace them. Don’t forget to refill your washer fluid reservoir…you’ ...[more]
