A local bike shop has a salvage yard (used parts) in the basement. I saw one Innova tire there. The lugs were all in good shape. The studs were worn completely flat. By contrast I had a set of carbide tipped studded tires that I sold after 4 seasons and they still looked good aside from some surface rust.

If you're only going to use them on ice and snow, they might be OK. They might also be OK if your goal is to "try out" a studded tire without spending a fortune knowing these may only last a season.

Finally if you live someplace where snow and ice are a relatively infrequent concern buying Innovas has some merit. Do you really need to spend $100 - $200 for tires you'll use 8 days a year? If you hardly ever use them and when you do it's on ice and snow, then they'll last long enough.
