Thinking about 16" tires

Hello everyone,

My '97 Ranger has stock 14" tires on it currently and they have a lot of life left. A good friend has a set of 16's on Ford rims that he would consider selling me very cheap. I have heard that this swap would change my final drive ratio for the good, but I am wondering about the spedometer. Approx. how much would this throw off my spedometer? If it's only 1-2 mph then I'm not going to worry about it, but if it's a substantial difference then is it really worth having the spedo recalibrated just for a small savings at the pump. The 16's would much better fill the wheel arch area and cut down on the massive gap between the tires and the fenders. Any advice is greatly appreciated. Thanks.
