Of the above choices, go with PS3 195/55/R15. Why PS3 and not XM2? Becasue PS3 is much better tire/high performance category, while XM2 is just low end econo tire. Why 195/55 and not 195/50? Because it's thicker sidewall so more comfortable, and reduce just a bit the risk of your rims scratch by stones etc because of taller sidewall.

However if you can find 205/50/R15 for PS3 then it would be better coz wider tire hence better protection and size match more for 7jj wide rims. Also since wider tires then better grip. The sidewall thickness is between 195/50 and 195/55 and still >10cm sidewall so still relatively comfortable, and should match your original total diameter closer than 195/55.
