Tires: Changing to different size tires, series tires, factory wheels

Question
My daughter has a 1989 Honda Accord LX1 Sedan. The car was originally equipped with P195/60-14 tires. A previous owner replaced those with P205/50-15 tires and 15x6 alloy wheels. We would like to purchase new tires but do not want to pay the price for the "50" series tires. We would like to go to a P196/60-15 or a P195/65-15 but the difference in overall diameter is 1 inch and 1.8 inches respectively. How do I determine if I can get away with this?

Answer
Hi Tom

If the rims are the factory wheels i would go back to the size they came with it's better for the car unless it's modified for performance .The "50"series tire you are talking about is a low profile titre and they are expensive then a regular tire would be due to the fact they last longer and perform in speed and corners.  But if you and your daughter find no need of that then i would stay close to the manu regulations since you have 15 inch wheels the 2 sizes you mentioned will work but the  Diameter Difference: 3.09%

So that means the 195/60/15 you mentioned is a little wider tire then the "65" series depending what you want and the question if it will rub or not.
Hope this helps
