Since then, four wheel drive vehicles are a popular car, truck, and SUV of choice, especially if you live in a part of the United States that has snowy winters. The term "four wheel drive" means that all four wheels on the vehicle are being powered by the engine at the same time. It's also known as "4WD" or "4X4".
There are basically two types of 4X4 drive systems: (1) fulltime or all of the time - which means that the vehicle is permanently in this mode. (2) Part-time four wheeled drive means that you can manually change it to two wheel or four wheeled drive.
One advantage of this type of vehicle is that if one or two wheels are spinning on ice or snow, one or two of the other wheels can still have traction and enable the vehicle to move. Cars, trucks, or SUV's that are equipped with only "two wheel drive" have a definite disadvantage in this respect. If both wheels lose traction and are spinning on ice or snow, the vehicle cannot move.
Some four wheel drive owners still put chains on their tires when the weather in their area turns nasty, though. The reason for this is that the chains provide additional traction when they bite into the snow and ice.
And as far as tires and tread go, large, wide tires can put more rubber to the pavement. But when the roads are covered in deep snow, these same tires can ride on top of the snow. This is known as the "Snowshoe Effect." This effect might cause you to lose the ability to steer, brake, and handle your vehicle on the slippery snow. Thinner tires, on the other hand, have a tendency to dig through the snow and provide better control.
If you have a 4X4 truck, you might want to add bags of sand or kitty litter to the bed too. This extra weight will help to add traction to the rear wheels.
But, you may be asking yourself, if I drive a four wheeler, why would I need chains or extra weight?
One mistake that drivers make - especially the green ones - is to assume that since their four wheel drive vehicle can go, that it can also stop on snow or ice. But when it comes to stopping in wintry conditions, a four wheel drive can be just as much of a two ton "pig on ice" as any other vehicle. Why? Because, if all four wheels are on slippery ice, for example, what's going to help the vehicle when you hit the brakes? It doesn't matter if it's four wheels or two, it's still just rubber on ice. And that combination can mean sliding out of control. Again, this is why some owners of four wheel drive cars, trucks, and SUV's put chains on all four tires in the winter time.
So, if you're the proud owner of a four wheeler, keep in mind that your vehicle does have the advantage of having power to all four wheels. This can provide better traction when you are driving in the snow. This is probably the biggest reason that you decided to purchase this type of vehicle.
But, you must also keep in mind that your four wheel power isn't going to provide any better stopping traction than a two wheeler has. Therefore, you should always drive carefully in the wintry weather in order to avoid having an accident.
Careful driving will also help to keep the costs of maintenance down. One of the disadvantages of owning a car, truck, or SUV that has four wheel drive is that the parts and service cost more.
