You can see why this might be a problem on a miata autocrossing with wide tires - they never get into the tires optimum temperature range. Anything over 195 in a miata is iffy if you are trying to get the tires to heat up quickly.
Keep in mind that a bigger tires doesn't mean a bigger contact patch - it just changes the shape of the patch.
I rotated my 225/255 setup to put the 225's up front (just for kicks). I can't say it really handled any better - I had less turn in grip at lower speeds (autocross like).

I'm not sure how the topic got switched to Miatas. Irrelevant to the discussion of going 265 all around on a 335.
Are you saying that you run normally 255 up front and 225 rear and for kicks you switched it around to 225 up front and 255 rear?
