Wheel And Tyre Size Query...can Anyone Help?

[kai14]

Hi, i have a 2000 Yaris 1.0 GS, now looking for buy an new set of wheels and tyres for my car but got some query not sure about before purchase, hope anyone at the forum can give me some clue, Thanks!

Wheel size is: 15x7.0J PCD/ Stud Pattern: 4x100(X-drilled) Offset ET38 Bore: not sure(think they come with the Spigot rings to fit the standard bore size 54.1)

1/ Dose these the correct Wheel size for my car?

2/ If so, what's the correct tyre size for the wheel?(195/50/15) or (195/55/15) i'm not sure about, because it suppose to fit (195/55/15) after read through many posts and used the Tire size Calculator(195/55/15) is the closest diameter compare to standard: (175/65/15). But some said (195/50/15) is the correct size, other said if u use 55 Profile have to go for 185 Width(185/55/15) not the 195 Width, these really make me confuse.

3/ If i go for (195/55/15) would it cause any problems?(e.g: scratch the archs or scratch the Shock Absorbers when steering? (Will lower the car 35mm Front and Rear)

Thanks.
