Speed & MPG comparison - Toyota Yaris Forums

RWJC · 05-13-2015, 10:07 AM

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!!

I don't run 17"wheels, but you have me curious. Have you accounted for the heavier rotational mass in your decision to go with a bigger wheel tire combination . My 15" Spaco's weigh less that the stock steelies 15" with hubcups. As a result my numbers improved very marginally (.2 mpg) over the stock wheel mpg.

yes, I considered and knew what the wheels cost me, was hoping the CAI or more air would help, like it did on my bike.
