what tire size can the stock rims fit into?

[SuperTurbo]

OK, once I find out the tire is actually a donut tire, 185 tire.... with sport package, my first impression is....

and I ask them, any upgrade for that, the answer is

So my question is for a 5.5inch wide rims, can it fit a 195 into it? or may be even a 205?

Other than that, do you guys hear the stock tires like to scream on even like a 40km of cornerin?
