friends tire size 205 55 16 --- 205 60 16 or 205 50 16 when there is a significant decrease or increase in fuel, is there anyone who has experience in this regard?

Etkisi mutlaka olacaktir ancak ne kadar olur onu soylemek biraz zor.
En azindan hiz kadraninda gordugunuz o anki hiziniz ile disaridan diyelimki polis radarindan tespit edilecek hiziniz ayni olmayacaktir. Ornek asagida:


Original lastik Yeni lastik
205/55 R16 205/50 R16
Cap 315.95 305.7
Cevresi, mm 1985.17 1920.77
Cevre farki, mm -64.4
Cevre farki, % -3.24
Hiz farki
50 km/h 50 48.38
80 km/h 80 77.41
100 km/h 100 96.76
120 km/h 120 116.11

So what is the ideal air pressure of the 205/55 / R16 tire?

When you open the left door of the vehicle, it writes the required air pressure for the color code and tires of the vehicle. You can look in two different ways, both loaded and unloaded.
The air in the 307s when idle is around 34-35 psi, but I hit 33 because it shakes a lot.

Thanks
I pressed all 34 but the air looked a little low on the front tires.

It does not play much fuel savings in dimensions.

our friend koliva explained very well, in addition to this, what is your reason for cheek size change? Generally, when the rim diameter is enlarged or reduced, there may be differences in cheek size, so I asked. For example, my original size was 185 * 65 * 14, I wore 195 * 55 * 15, there was no increase in fuel and my speed on the speedometer remained the same by adjusting the cheek size.

I think the tire diameter affects fuel, and the weight of the rim is also a different matter.

If you do not go out of the standard, your fuel will not change in your his indicator.
The 307s have standard sizes for each rim length. these are respectively;
For 15 "jan; 195/65/15
For 16 "rim; 205/55/16
For 17 "rim; 205/50/17
For 18 "rim; 225/45/18
