Speed & MPG comparison

[RWJC]

I am a new Yaris owner, of a 2014 5 door hatch. I needed new tires, and the stock would not accommodate anything wider than a 195. To make a long story short, A friend who runs a tire shop made me an offer on an 18" wheel/tire set I could not pass up. I know it affected my MPG, but I never recorded my stock /OEM MPG stats. I tried a search and did not find what I was looking for.

Here is what I am looking for. If you are a 2012+ 4 or 5 door, please post your MPG at the following speeds please.

If anyone who has 17" rims or larger or a width 205+; with a STOCK intake, can post their MPG @:
25-
45-
55-
70-

I would be appreciative. Also, specify city & state you are in. Thanks in advance all!!
