I have Axio Hybrid as well, I replaced my vehicle tyre to 195 , drawback of it was my hybrid advantage of fuel average came down to 16-19kmpl , Therefore, I sticked with 185/60/15 and I cross speed/car breaker by Diagonal way ,
I think if you install spacer on all 4, your hybrid avg won't be effected much.
If avg is not your concern. you have good option of Yokohama BluEarth and Bridgestone Ecopia.
