Replacement Tire Sizes - Toyota Yaris Forums

EasyDriver · 06-10-2009, 12:01 AM

I was just looking at http://www.miata.net/garage/tirecalc.html today investigating what tire I would get to replace my 185/60/15s. Mileage is my primary concern since yet again gas prices have risen to $2.95 here in lower Michigan. Every tire I have had in the older 70 & 60 series has worn poorly. If I was picking a 15" tire for my Yaris today I would get a Goodyear Fuel Max 195/65/15....more tire height, less revolutions per mile=more mpg. Not a lot maybe...but 2% or close to it. It seems like the majority of Yarisworld prefers the cooler looking wider series tires. Perhaps our Hypermiler members could shed some light on this.http://yarisworld.com/forums/images/smilies/biggrin.gif

Going from 185 to 195 will decrease your mileage more than going from 60 to 65 will increase it. You might still end up with an overall increase in mpg using fuel max tires though.

if your looking for mpg, and mpg only; a skinnier tire is more important, not a wider one. less rubber, less friction. and a taller tire does exhibit less rotations--but in town driving may suffer from you trying to overcompensate and is generally not a huge factor unless highway is your mainly your thing.

the standard prius has (to my knowledge) 185/65/15. i'd shoot for that if fuel was your concern-- someone on a forum mentioned goodyear integrity's as a good tire for this application, i'll see if i can find a link

just remember, you'll be travelling faster than your speedo reads (@ 60mph = ~62mph)
