- i've been thinking about why chains are required.
- they let you go without chains if you have 4WD/AWD
- or snow tires.
-
- i have a feeling that the reason chains are required is
- more out of a desire to see that you don't get stuck and
- hold everybody up than to make sure you don't crash.
- chains are not required on all four wheels, and you are
- supposed to put them on the driving wheels.
- in the case of FWD cars, putting them on the front aids in
- acceleration, braking, and steering. in the case of RWD
- cars, however, putting them on the back aids in acceleration
- only, does little to help braking, and is of no benefit to steering.
- and the presence of 4WD/AWD helps only acceleration, not braking
- or steering. a GMC syclone with gatorbacks all around would not
- be required to have chains or snow tires.
-
- it sure sounds to me as if they just want to make sure you don't
- get stuck and hold everybody up. and when traffic is sparse,
- i have trouble seeing a good reason to slap those chains on if
- you're not having a lot of problem getting the car moving.
- furthermore, if you have chains, you can't go more than 30 mph.
