For more selection and an excellent fitment, replace with either 185/60/15's or 195/60/15's.

^^^^^ This. I could definitely tell the difference between the 175/65/15s on the '13 LE and the 185/60/15s on my Yaris.

im kind of a slave to the mpg's, so I like to stick with the narrower 175's. plus the skinnier tires are (in theory) a little better in the snow. the oem's are such garbage, I think the biggest improvement will be dumping them. I think I will look at what is available in the wider tire, but would 185's fit properly on the stock rims?

edit after a few minutes on tirerack: come to think of it, I don't think I want any less profile on the yaris. its not the smoothest car over bumps and such and a lower profile isn't going to help. those pilot a/s 3's look like one of the best all season tires (ratings wise) in existence, but im sure they will not maximize mpg's.

Do you think the narrower tires on your 3rd Gen account for the up to couple MPG improvement over (a few cars ago, as you mentioned) your 2nd Gen Yaris ? (The search I did indicated they have the same relatively slippery CD number...and that there is only a 5 lb weight difference)

maybe. a little less weight to turn and im pretty sure they have pretty low rolling resistance. it also seems like my 07 ran just a touch higher rpms on the highway. even a very small improvement in coefficient of drag can make a difference.

I know I will not go through another winter with these awful, awful, awful tires. did I mention they were awful?

Good point. Even with the 07 Model Year different tire sizes were available from the factory, so (re both 07 and 14) I wonder what size tires and wheels were used during the test?....or...Is the factory quoting the CD for just the body (not with any tires/wheels) ?
