I'm Shabaz - Regional Head of Bridgestone. It all depends, and ALWAYS depends on the original overall diameter of the vehicle as to which sizes you can safely fit.
As long as your City is not a 1.5steermatic, then the original size on the car was 165/80 R13. When you plus size to a 14"rim, your perfect substitute is 185/65R14.
Now if you want to go wider, the size would be 195/60R14.
The 195/65R14 size is NOT suitable for your vehicle, it will affect your speedometer adversely as well as your handling and possibly even your braking distance. Even the 185/60R14 is not advisable, the speedometer being about 3% too fast. People who are advising you for these sizes dont know what they're talking about.
As far as the comments regarding fuel economy, they're ridiculous. A 10mm increase in footprint, not even that in reality, makes absolutely no difference to fuel economy. In fact some low profile tyres have a lower rolling resistance, which actually means an improvement in fuel economy....
Bridgestone is the number one tyre brand in the world, the only approved brand in Formula One, and the largest annual repeating Research and Development Budget of all brands globally. The B70 is an excellent tyre, as long as it is bought from a source where you'll get a fresh, warranted tyre - not smuggled b-pairs as most sellers give.
