Wheels/Tires on Kaminari Yaris

[Thirty-Nine]

Well if stock is 185/60/15, then the "correct" size would be either 205/55/15 or 195/60/15. But it seems most people here run a 205/50/15 or 195/55/15, both of which are smaller. I realize they'll provide better acceleration and some think they look better, but you're also putting more miles on the car with a smaller diameter. Granted, I'm not sure how many more miles. It could be very minimal (I'm sure we could figure it out).

In fact, between a 185/60/15 (850 revolutions per mile) and a 205/50/15 (874 revolutions per mile) there's 24 revolutions difference.

My math stinks so feel free to correct me:

1 mile / 24 revolutions = .04 additional miles
.04 miles x 15,000 actual miles per year = 600 extra miles a year

(Is this right?)

no your calculations are way off, first of all speed will change this anyway but I figured something like and extra 300 miles on the car at 10000 miles, very minimal, someone on here figured an extra 3000 miles at 10000 miles, he is wrong too, the difference is minimal and worth the extra boost and lighter weight to me, oh yeah and it looks better and no rubbing issue with wider tires

are you sold yet?

Like I said, I suck at math.

Sold? I don't even have a Yaris yet!

I remember when I was looking for tires for my Civic, a lot of people would run 195/50/15s because the looked better even though the correct size was 205/50/15 or 195/55/15. I just want to make sure that it looks good and won't add too much unnecessary milage. First I have to worry about getting a Yaris!

205-55-15's can cost up to 20% more than 205-50-15's. also, fewer brands offer 205-55-15.
