Its not a good idea to have different tyres on the same axle. If you are just changing one I would go for one that's the same as the other side or at least one of similar specs.
Not sure which wheel and tire combo the Panda Miami has
Post the size from of the sidewall. For example mine are 155/80R13

There no such thing. Some are quiet, others grip well in the wet, some
Are economical and other wear well.
Deep block treads for snow and ice and grooves for rain.
Near slicks for dry roads and so on.
Its a compromise for example the best wet grip might be the noisiest.
You have to work out which parameters are the most important to you.
Here in the UK. Online tires only normally don't work out the cheapest.
I paid £42 fitted for mine. They are £35 tyres only. Very few places would fit, balance and dispose of the old tire for £7. In fact the cheapest for the tyre I wanted was £35 all in just a bit too far out.
