First, no one is going to be able to answer your question with any degree of accuracy. To understand why, you need to read this:

So your proposed going from a 285/40R15 to a 225/50R15 is going the wrong direction for load carrying capacity. You are going smaller in load carrying capacity and that's the wrong direction for RR. Try a 255/50R15 or something like that.
