- I take it you've never been in a situation where you needed them.
- Ever tried making a steep climb on ice? Without chains or studs
- you're out of luck, and it's dangerous not only to you but to
- whoever's behind you when you start sliding backwards.
-
- They can save your life and the lives of those near you. They're a
- really good idea in bad situations.

- Unless your car doesn't have rear brakes they'll help a lot in braking
- a RWD car. It aids in steering too because it helps avoid massive
- oversteer which I'm sure your aware is sooo easy to cause when driving
- a RWD vehicle in slippery conditions.

-
- Bzzt, wrong answer, for the same reason as RWD cars, but of course
- chains on all four tires is the best answer all around.
-
- >furthermore, if you have chains, you can't go more than 30 mph.
-
- That would depend a lot on the design of the chains, but if you need
- chains you probably shouldn't be going more than 30 anyway.
