noreast Report post Posted January 20, 2010 I just ordered a 2010 Fusion SEL I4. By law we are required to install winter tires in here Quebec. The size is 225/50-17, but these babies cost an arm and a leg a piece. I am thinking of buying 16" steel wheels and installing 205/60-16 tires on them. The difference in price per tire almost covers the cost of the wheel, which is a bonus since I can spare the original wheels from the insults of winter driving.The circumference difference between the two tires is about 14mm, so it is negligible (I did the math and using 206/60-16 amounts to 3 extra revolutions per Kilometer, or the equivalent of driving an extra 30Km per year). I am not therefore concerned about the difference in circumference, but more concerned about the narrower contact area 205 vs. 225). For snow and slush driving this is an advantage since narrower tires dig deeper and get more traction. But when the city clears the snow, it is back to dry pavement. Should I be concerned about this? Will it affect dry-surface braking? Quote Share this post Link to post Share on other sites
