What Should the Tire Pressure Be for Summer?
Huginn
I dont think there would be a great difference between a 225 and 235 however I have ZR rated tires (you sadi you have R?) That may have been the difference. But I don't think you want to have the rears wider than the front. I used to have 235/40 on the rear also for my bimmer and 215/40 in the front (the E36 M3 set up) and it was a lot of hassle because you can't rotate them. So just keep them the same all around.
