I put a set of these on my 2004 LSV8 this summer, they are the stock size as came with my car. I don't have more than a few thousand miles on them but so far they appear to be pretty good tires. I haven't pushed them to the edge yet, but they handle as well as the Goodyears I replaced. THe Michellin Pilots that came on the car wore out at about 36,000 miles. The Goodyears wore with about 40,000 miles but some of that may have been alignment related.
I have not driven in heavy rain yet and certainly no snow. They are rated M+S so they should be OK in snow but not as good as a snow tire. They are made in Japan if that makes a difference. I got mine for $100 each plus the usual at Americas Tire. I showed them the webpage for Discount tires with that price, so they honored it.
So far my experience has been good. Assuming they work well in rain and have good tread life I would buy them again, but still too early to definite.
