Hi Guys,
One thing to consider if you are thinking about putting 14 inch 
wheels on your cars to replace the 13 inch wheels, the 14 inch 
wheel tire combination will be heavier than the 13 inch version 
which will also have an adverse affect on the handling due to more 
unsprung weight. Paul is on the right track in looking at tire 
diameter. You would be surprised to see how much it varies between 
various tires from the various companies.
