My 2009 Subaru Forester has mags with P225 55R17 summer tires.
I saw a good deal on craigslist for alloy mags I could use during winter. On the picture, I see the seller previously fit some P225 60R16 tires.
So with both setup, the total diameter would be around 26.7 inches, except with my summer setup there would be more wheel and less rubber, while my winter setup would have less wheel and more rubber.
I know the physics of having bigger wheels can have impact on performance, but what about when the total diameter is the same size, just different material?
I'm also a bit afraid the brakes won't fit in 16 inches wheels when they are currently in 17 inches wheels.
