205/55/15 seems like the best for City 09 and it was definitely the best for Corolla 2001-8 model which had 185/65/14 as stock size.
But I had to change my Corollas tyres and believe me I went crazy searching the whole of Pindi and Islamabad, and found NO 205/55/15 in ANY brand, ANY model - new or even used...:s
I found it in only one place, Bridgestone Potenza Adrenaline RE 001, but for 9k/ each. So I rejected them and went for the second option, 195/55/15, which too was scarcely available, but found Yoko A drive in 5500 each...:s
I recommend 195/60/15 - its widely available, has the right cushion (my assessment) and 195 is reasonable width. Also, its just 1.08% off the original diameter.
