I'm entering my 3rd on final season on my Blizzak LM22's. I'm planning on switching over to WS50's. I'm aware of their handling limitations but since my beater is one its last legs I may have to rely on my S2000 as my only option. I ran LM22's in 225/50-16 on all 4 corners so I could rotate them front to rear for extended tire life, dismounting and remounting front to rear. Would I be better off going with 215's all around or stay with 225's?

 

I would say for the winter you would be better with the 205/55R16 all the way around. The WS50 would be the best ice and snow traction.
If I can help let me know.

 

You might want to ask XViper too! He lives in Canada, uses his S2000 in winter and runs Blizzak WS-50's too. He could give you first hand feedback on this.
