I have a 92 F150. I've been thinking about lowering it some and putting larger rims on it. I don't want real low profile tires on it. I'm thinking that the overall diameter would be close to the same just larger rim with a little less rubber. It has 15's on it now that are stock, 235 75 15. I have a image in my head, but it probably wont look the way that I am hoping it will though. I'm kinda going for the rat rod look. Does anyone know if there is a web site or a way to measure without buying something and trying it out to see what will fit under the truck?
