I went the opposite way, from 225 winter tires down to 205.. 20milimiters smaller in diameter. I "guess" it must be a 10% difference (average) and when I now follow traffic at 120km/h (75mph) rather than the usual 110km (65mph).. So I guess that if I check my gas mileage, there should be a 10% difference too. Am I wrong?
By the way, these "low profile" tires (205/50/16) give exactly the same rough ride I didn't like at all on my former 900SPG. They're not that bad, but the smooth/semi-firm feel of the 9-5 is almost gone. Next tires will be different..
