235 having extra 4cm on contact in total will give u higher FC. However, it depends also what tyre you are using now and what you will be changing to.. If you are changing from performance to eco tyre the FC impact may not be significant thou..

also ur 225/55 upsize is not recommended as it exceed 2% differences
