Hi,
I am driving a 2009 hatchback vitz/yaris (SPC-90) with stock suspensions and wheels (with 185/60/R15 tyre) over a year now. Now, I am planning to change the wheels & tires. My choice is :
Rim : 7x15
Tyre : 195/60/R15 or 205/60/R15

Can anyone please suggest me if this is a good choice of rims/tires if I stick with my stock suspension and don't use any lowering spring/coils ?

Will 195/205 be too wide for a small car like this ?



Thanks :)

Go 205/55 instead of 205/60.

At 205/60, you are looking at your car being risen to almost an inch!!

Thanks IllusionX. But my current tyre is 185/60. Howcome 205/60 will be rising my car if I use R15 in both 205/60 & 205/55 ?
Sorry if I sound a bit dumb. This is my first car and I am changing the tyre/rim for the first time.

Appreciate any suggestion :)

In tire sizing the /60 represents sidewall height. This is not a fixed measurement, rather a ratio of tread width. Therefor, a wider tire with the same aspect ratio as a skinnier tire will have a greater overall diameter.

Btw, do u gyys think my stock suspension and scp90 chasis will be able to handle 205/55/R15 properly ? The roads I use for daily work are pretty rough & have lots of bumps.

And also, moving from 185/60/15 to 195/60 or 205/55.. does it hav any impact on fuel consumption ?

Suspension fine. The wider the tire, the heavier it is, with a wider contact patch affecting rolling resistance. Fuel economy takes a hit.
