go for yoko Db 185-70-13 , for best mileage with grip and soft steering.
or u can go to 195 but i must say, putting 14' rim means u have to compromise on profile, get it like 65 which will be less comfortable in comparison to 70, so choice is urz,
dunlop leman 702 tires are also gud and soft, they are gud too for smooth ride.
