Tires: Changing to different size tires, series tires, alloy 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
Tom,

First you have to be aware that changing tire size may change your speedometer reading.

Second, the worst case for fitment is fully turned, fully compressed.  I'm sure you can determine what the clearance is when the steering wheel is fully turned, but you'll have to take your best guess as to what adding fully compressed is going to do.

But usually there is enough room for this magnitude of change.

Hope this helps.
