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 togeth ...[more]
Nobody ever looks forward to a flat tire, and nobody ever says "well, that was a really good time" after having one. You can at least minimize the damage to your tire and danger to yourself, though.
Flats vs Blowouts
If you get a blowout, you'll know about it right away. Sometimes the tire can fail dramatically, with a bang as loud as a shotgun going off. Other times, it might just be a loss of air and a sudden change in your car's handling, followed by vibration, noise and a pull to one side. If it's a front tire that fails, your car might be a real handful to drive until you can get to a stop.
In either case, your first job is to pull off the road as quickly (but safely!) as you can. Don't jam on the brakes or make any sudden mo ...[more]
At one time, there were only a couple of choices for motor oil. Today, that is no longer the case, and hasn't been for quite some time. Here's a quick breakdown of what you need to consider when it's time for an oil change:
- Viscosity: Viscosity is how thick your oil is, and how it retains its pour properties at various temperatures. In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. Check your owner's manual -- many newer models require a thinner, lower-viscosity oil, which also helps the engine run more efficiently. Viscosity is expressed as a numerical value -- the lower the number, the thinner the oil. Many are designed to work a ...[more]
When it comes to your car, oil isn't the only thing there's a finite supply of. Rubber has its limits too, and it's estimated by 2020, the supply of natural rubber in the world may be outstripped by demand. And of course, tires require a great deal of oil to produce as well. Tire manufacturers are constantly looking for ways to innovate and conserve resources in tire production. Here are some recent advances:
- Dandelions: Yes, those humble yellow flowers you try to eliminate from your yard. Dandelions actually contain a minute amount of latex in their milky oil, and research shows they can actually produce about as much latex, pound-for-pound, as rubber plants. German scientists have cultivated 1-foot-tall dandelions for just this purpose. This isn't a new development, either -- in WWII, Amer ...[more]
Driving around on underinflated tires is just a bad idea all the way around. Underinflated tires increase a car’s rolling resistance, meaning a drop in fuel efficiency since it takes more energy to move the vehicle down the road.
A single tire that’s down by ten pounds of air means a 3.3 percent drop in fuel economy…multiply that by all four tires, and you can figure on giving up ten percent of your gas mileage. The added friction and rolling resistance also means more heat is generated, and heat is the enemy of the internal structure of a tire. That heat will damage a tire to the point of failure. Studies show that underinflated tires are a full 25 percent more likely to fail, and at least half of one-car accidents involve a tire problem as a factor. And still, it’s estimated ...[more]
Often, drivers are mystified by how their cars actually work. It’s to be expected. Even an older car is a complex machine with many sub-assemblies that all work together to move it down the road.
As a result, drivers tend to be a little intimidated by auto repair and often tend to not inform themselves by asking the necessary questions of a tech or a garage. Too often, that ends up being a big mistake. Here are some examples of the kinds of things you really should know before any auto repair work starts:
- Does your shop work on any kind of vehicle? Of course, most shops can service a product from GM, Ford, Chrysler, Nissan, Toyota and the other leading makes. Some makes, however, require a lot more training and experience, o ...[more]
