For 4 wheel drive vehicles, the primary drive axle is usually the rear axle (you can confirm this in your owner's manual). Chains are only legally required on one axle (two wheels), but you can put them on all four tires for even more controlled steering. Tire chains are not permitted on many all wheel drive vehicles, so check your owner's
4 wheel drive ATVs that allow you to switch to 2WD will start in 2WD. You need to activate the 4WD when the RPMs are below 3,100 and before you encounter the conditions that require 4WD. If your rear wheels are spinning (have no traction), you’ll need to release the throttle before switching to 4WD or you could damage your gear case or drive
They work to maintain the traction between the snow tires and the road surface in inclement weather situations. This feature limits wheel spin while the tires are in motion. This increases the contact between the tire and the road, allowing it to regain traction in ice- and snow-covered roads. Now, let’s discuss what traction control is not.

Locking differentials are best suited for off-road or low traction environments. With a locked differential both drive wheels will turn at the same speed making turning more difficult if you have full traction. This will give more wear and tear on your tires on asphalt and your tires will chirp as you go around a turn.

The Prius is a front-wheel-drive vehicle that, per Toyota, comes equipped with standard all-season tires. While a dedicated winter tire offers more traction and performance, all-season tires are
Obviously, all-wheel drive and four-wheel drive deliver that best. However, not everyone wants to drive a hulking SUV year-round in an area that only gets snowfall a couple months out of the year.
