Requirement 2 (R2): Chains or traction devices are required on all vehicles except four-wheel/all-wheel drive vehicles with snow-tread tires on all four wheels. NOTE: (Four-wheel/all-wheel drive vehicles must carry traction devices in chain control areas.)
Do you put chains on all 4 tires with 4wd?
Four-wheel drive vehicles should use tire chains on all four tires. You must use tire chains for those wheels on the drive axle for two-wheel drive vehicles, but it’s much safer and easier to control if you have chains on all four tires.
Do I need 2 or 4 snow chains?

Do chains damage AWD?
Re: Chains on AWD
Putting chains on can cause damage to the transmission and void your warranty. If studded or non-studded snow tires are not enough, try Auto Socks or Spikes Spiders.
Should you put chains on AWD?
While you can probably safely drive your AWD (all-wheel-drive) with all-season tires in light or moderate snow, it’s a common misperception that AWDs will act like a tank in slick conditions. That just isn’t the case. You need snow or winter tires or even snow chains when facing severe winter roads in any vehicle.
All-wheel-drive systems deliver power to all four wheels at the same time, or they automatically engage torque to all four wheels when needed. That’s why all-wheel drive is best for driving on snowy and icy roads.
Does 4 wheel drive help on black ice?
QUESTION: Is four-wheel drive better for icy roads? ANSWER: Yes, all wheel and four-wheel drive are better in ice and snow.
Is AWD or 4WD better in rain?

Does AWD use more gas?
AWD cars also offer worse gas mileage than 2WD rivals because they’re heavier. AWD and 4WD drive systems can add hundreds of pounds to a car’s curb weight, and that extra bulk can have a big impact on fuel economy.

Drawbacks of AWD
Vehicles with AWD will usually be more expensive than the same vehicle with a front or rear-wheel drivetrain system. The complexity of the AWD system is a little more complex, which may also lead to more expensive maintenance.
Can you switch to AWD while driving?
Older 4WD systems must be manually shifted between 2WD and 4WD and from 4HI to 4LO while the vehicle is stopped. Newer s 4 wheel drive systems have electronic push button ‘on the fly’ features that let you shift while driving. An AWD car can deliver all engine torque to all four wheels all the time.
Always turn off the AWD when you are on the road unless traction is at a premium (ice, snow, mud etc). There are reasons for this. First up is the fuel saving, by running two less wheels, there will be less drivetrain losses as well as more fuel efficient. You will also reduce the wear on the tires as well.
Does AWD help resale value?
Most AWD vehicles offer better resale value than their two-wheel-drive counterparts. There’s a reason: AWD costs more up-front, and it makes a vehicle more capable.
