Interesting. What is the actual legal definition of a "summer tire" vs. a "winter tire"? Herbert Graf wrote: > Really? You are FORCED to use winter tires??

Well that, and I wish positraction were a standard > feature on all cars, but hey, some people seem to love finding out how > much flooring your car when you've got zero traction helps... :) TTYL Positraction is just another name for a limited-slip differential, which actually makes it easier to spin out on snow and ice if the driver fails to limit the engine power. Perhaps you mean some sort of active traction control system, which either limits engine output or selectively applies brakes (or both) when slippage is detected. In any case, no amount of technology can fully compensate for stupid drivers. -- Dave Tweed -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
