I have recently put alloys on a 1995 Mentor. I went for 16inches with 205/45/16 tyres. Although they look fine I thinks its just abouth the maximum I could have gone. As a pride is a smaller car I'd say 14's. However if you wanted to look flash you would get away with 15's.
Just remeber that increasing your wheel size can effect your gearing, this means your speedo won't read correctly and you could lose acceleration. The way to solve this problem is to choose lower profile tyres to go with larger diametre wheels. A general rule of thumb is if you go up one rim size, decrease one profile size.
When fitting my wheels I found Kia alloys to be expensive. If you wanted to increase your choice you may find it useful to know the other makes that will fit the bolt pattern on your wheels.
I'm sure, like a mentor, your PCD (pitch circle diametre) is 4*100. If so the following cars alloys will fit your pride:
