Was reading my December issue of FHMUS (the magazine for people afflicted with ADD) and noticed the following interesting tidbit - tyre-grip. More info at http://www.tyre-grip.com. Looks interesting although no doubt not a substitute for a good set of winter snow tires.

Anyone ever try this stuff with their winter tires (or tyres if you're of British persuasion).

 

for a second it reminded me of Paragon the sauce you use on RC car tires.
