totally wrong, bigger tyres would make your car consume lots more fuel and cause more wear. it will also be not that much comfortable or certainly worse to drive since you are lugging those heavy tyres and in a small car the best you can do if you want more clearance is to increase size to 195/65 R 15 , but they will look odd and you might touch the fender inside when overloading if you go for any bigger tyre or rim size
if you want in 16inch then you will need 205/55 r15 and they will denfinately not give you a soft ride
rather then get cheap chinease wheels, i would suggest keep your original rims and just get really good quality tyres such as continental, you'll love the drive and just take it easy over bumps, don't overload
