just my personal opinion
no stock tyres are NOT ok...they are very very hard, lack road grip and result in poor braking. you must switch to a quality brand like Yokohama, Michelin or Continental....my say is that stick to 185/65/15....195/65/15 are a little too big for the car and suit Civics and corollas more...also 195/60/15 is ideal....for a set of 4 tyres, keep in mind to spend around 40k plus minus few
there is nothing WRONG with the city automatics, but they are pretty sluggish, specially at low RPMs. i have driven 1.3 automatic and it was a horrible car to drive to be honest, yet on the other hand, manual 1.3 is a lovely lovely little machine to keep. i havent driven 1.5 automatic yet so i really cant comment. but also remember, autos give very poor fuel average. the 1.3 auto i drove used to give max 11 km/liter within City with AC, whereas my manual regularly touches 15 and sometimes beyond. rest its your choice. if auto is ur preference, i wud much recommend an Axio instead. a far far better car than city, excellent power, superb comfort and a lickably quick engine
