That sidewall sizing difference puts you almost 7% out. I'm not sure if I'd do it, personally. Because all 4 tires are the same size, nothing will be hurt by it... but 60 sidewallls. EW. :P
As for the P6s... what's wrong with them? I live in North Bay and I've done 3 winters on Pirelli P6s. I was stuck once this year of my own stupidity (in my driveway, no less) and that's it.
