I live in Michigan and definitely would require all season tires from late October thru mid April so may as well do the entire year with minuscule (If any) trade off Current users report zero issues with the 1 step upsize front tires. The Pilot Sport all season is available in the standard rear tire size. One could go up 1 size with the rear tires if so desired (But not necessary).

This seems to be the consensus outcome for those who have done actual tire comparisons. Probably would have to do comparison testing on a track to perhaps find noticeable differences (Or very aggressive driving on a public street).
