hey i too have to replace all the tyres on my santro.
i suggested my dad for 165/65 r13 , his first statement " mileage will decrease"![Big Smile [:D] [:D]](https://www.theautomotiveindia.com/forums/images/smilies/Big%20Smile.gif)
i don't think mileage is a concern in CNG.
anyways i don't know how much hard the steering will get with the wider tyres
since it's driven 100 kilometers daily in city traffic.
