I will discuss about the 145/80/R12
145 means the width of tread area (the portion that touching ground),
80 means aspect ratio, the height of tyre from tread to rim, expressed as % of width (145).
'R' stands for Radial, the construction type
12 means the diameter of of rim.
As the rim diameter increases, you have to decrease the profile of the tyre
Riding comfort may vary if you use a very low profile tyre.
If you are using Alloy wheels, wide diameter give a better look.
Changing tyre size as you mentioned may not cause any difference except its external appearance. Before changing tyre size you have to read the owners manual regarding the suggested tyre sizes for a particular vehicle. Some wider tyre may cause impingement, alignment problem, decreased fuel efficiency etc.
