There are so many tire designs on the road -- all-season, high performance, touring, light truck -- and even within a specific tire design, there may be several choices of tread patterns. What differentiates them, and what are the pros and cons of each tread design?    -- Directional tread has a pattern of grooves and chevron shapes, all pointed in one direction. This design makes it easy to direct water away from the tire's contact patch and prevent hydroplaning in wet weather, and also ...

For some, the idea of an "organized car" is almost blasphemous, but having your vehicle set up so you can actually find things can be pretty nice. The bigger the vehicle -- minivans, SUVs -- and the more people they haul, the more disorganized they can get. Don't let your minivan turn into a rolling dumpster -- here are some great ideas for keeping it organized.    -- While newer vehicles have come a long way in terms of driver and passenger ergonomics and an abundance of cubbies and cuph...

The tire is such a commonplace item -- it's on every car, every truck, every bicycle, every aircraft. It's easy to not give the tire a second thought, but like every other technology, the tire has an interesting history of advances and failures.    In the 19th century, carriages and wagons used steel strips for "tires" on their wheels, with the punishing sort of ride that you'd expect. In later years, they were shod with strips of natural rubber, which was an improvement but was still pro...

You go out to your car, start it up, pull out of your parking space and see a puddle of...something...where you were parked a moment ago. This is never a good feeling. What could it be?    Fortunately, some automotive fluids are dyed different colors to make this a little easier to narrow down.    Does it appear to be water? Were you recently running your A/C? Chances are that's just condensation from the A/C system, which drips out through a rubber tube and is perfectly normal. No wo...

Believe it or not, the A/C system in your vehicle is fairly simple in principle and design. Like your refrigerator, it operates on a cycle of compression and expansion of a gas, known as refrigerant. The compressor turns the gas into a liquid, and as the gas evaporates it provides cooling. Like your refrigerator, its main components are:    Compressor Condenser  Receiver/dryer Thermostatic expansion valve Evaporator Refrigerant Blower  The good news is mos...

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 ...

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 specializ...

Buying a used car is somewhat less of a crapshoot than it was at one time. You can get detailed information on a vehicle's history via the CARFAX report, and a technician can use onboard diagnostics to get a good picture of what's going on under the hood and what problems might be coming up.    It's always a good idea to get a mechanic to look over any prospective purchase, but there are things you can get a look at yourself before you spend the money for a professional inspection. These ...

So you got a new set of wheels – congratulations! You’re going to want to hang onto it as long as possible, so you’ll want to keep it maintained as well as you can. Here are some suggestions: First, read the owner’s manual carefully and stick to manufacturer’s recommendations for service intervals. There are certain things that are critical enough that failure to adhere to recommendations can void a new car warranty. Don’t let that happen! For instance, just about every manufacturer...

Head into the showroom at any tire retailer and you will find a dizzying array of tire types, sizes, tread patterns and other variables that can have you turning right back around and heading the other way.  The good news is a step-by-step approach to choosing the right tires for your car, truck or SUV with a little knowledge can make the process much simpler and give you great results. The type of tire you need depends on what kind of vehicle you have, your driving style and the type of we...
