While different vehicles have different needs, you may see lower upfront and repair costs during the course of ownership. If you drive on dirt roads that are frequently muddy, they can provide more confidence when it matters most. But if you drive mostly on the highway and live in a temperate climate, you may be better off spending your money elsewhere. A great pair of snow tires can make even the most unsuspecting two-wheel drive vehicle ready to tackle cold-weather conditions.
Make sure you have the best all-terrain tires , the best all-season tires or the best winter tires for the job. And if you're stuck in snow or sand, your vehicle has a better chance of getting unstuck with 4WD or AWD.
That said, neither feature is foolproof. You should still drive carefully and pay attention to hazards. To determine if AWD or 4WD is worth the expense, ask yourself whether you're likely to be in situations where your car gets stuck.
If you frequently travel on dirt roads or live in a part of the country where it often snows, then the feature makes sense. Understanding how the four-wheel drive, low-range transfer case, and locking differentials in your truck work is key to getting the most of it off-road and driving safely anywhere. On pavement, where you have a lot of traction, your wheels need to spin at different speeds when you go around a corner. Your outside wheels must travel a greater distance around a corner than your inside ones, and the relative speed of the front and rear wheels will also vary.
This works great when you have good traction, but because torque will follow the path of least resistance within your drive system, it allows the wheel with the least traction to spin freely in slippery conditions. If your truck nominally functions in two-wheel drive, this will send available torque to the rear wheel with the least traction. If you have full-time four-wheel drive functionally similar to all-wheel drive , torque will go to whichever of your four wheels has the least traction.
Four-wheel drive locks the speed of the front and rear axles together, meaning that the wheel with the least traction can spin only as fast as its counterpart on the other axle.
This doubles your traction. Because the front and rear axles need to spin at different speeds on the road, you should activate 4WD only when your tires leave the pavement. That might be turning onto a dirt road or entering consistently snowy conditions, where the road surface is completely covered. Four-wheel drive doubles traction in slippery conditions, but it also requires slippery conditions to work safely.
You will not gain braking ability or stability when braking through turns with 4WD. Improper use of 4WD can break the front axles, shear the differential gears, and break apart the differential case differentials give power to your wheels and allow them to rotate at different speeds. The process for engaging and disengaging 4WD varies from vehicle to vehicle. Up Next. Anxious about driving on snowy roads over the holidays? We say, "Snow worries! Need winter vacation ideas?
