Thanks for the info! No plans on adding them to my tires. In my neck of the woods, we don't get a lot of snow, but it seems like every 4 or 5 years we will get slammed with feels/looks like a northern winter. A lot of folks think this is our year for it, especially with the cooler summer and much rain. If that continues into fall and winter, we will be in for a lot of snow.
I've read a lot of debates on chains, ags, etc. - I guess I've been lucky. I've gotten around great with just ag's and wheel weighs. Not much ice to deal with over the years, and when it's there - at least out on the street, it has already been chipped-up with snow tires and chains - and refrozen into a choppy surface that the ag's can get a grip on.
I just saw the studs and figured I'd ask if anyone had used or seen them on an IHCC.
