On the subject, has anyone found that the Innova's suck on glare ice, compared to Nokians or anything with Tungsten Carbide? I have Innovas and I was on a path yesterday morning and it was glare ice... ended up "kissing Canada" 4 or 5 times... it could be that I stink riding on ice, but I'm wondering if anyone's found that the Nokians are far superior (or in any way superior) to the innovas on ice?
