My winter wheels were my inspiration as well. According to the calculator in the other section, that is 3.4%. If your shown speed was 60mph, the relative actual is 62. In theory, doing so lower both the acceleration & consumption by an hair. I am very pleased with the result. I fixed three wheels and replace 1 tire with the 225/40.
Here are my new shoes (excuse my crappy pic).
