Yes you can easily put 155/14 or 175/14 on the same wheel, but you should look at that third number wich means tyre height. For example 60,65,70 and so on.
First number can be changed, second one-never and the third one can be, but it is not advisable

If you fit wider tyre's you should reduce the profile of them accordingly to match the original wheel diameter as near as possible.
If for instance if your tyre was a 165/70/14, where 165mm is the width, 70 is the aspect ratio (percentage of width), and 14 is the rim diameter in inches.
Your overall wheel diameter would then be 586mm, you need keep within a few millimeters of the original size for the speedometer.
