no idea on tyres avialable or the price diffrence

Yes, 195/55R15 is the Sierra standard rolling radius, but my impression is that 195/50R15 is by far a more popular size.

you need to get a lock nut on there as well so its mega close and if you have a flat in the rim it will touch

as for ride hight i feel the need to point out that if you fit bigger/smaller rolling radius tyre/wheel combo's you want to ajust the ride hight figure the same amount just as if you put the std wheels on, set the hights then, changed the wheels over
i hope that makes sence
