Can't stagger sizes on an AWD Lexus unless you want to risk damaging the drive line... You must run same size, same brand, same tire on all 4...

You can run as along as rolling diameter are the same. Go with 225-35 and 255-30

Problem with that is that there is no such thing as two different tires the exact same diameter... Heck there can be as much as a half inch in tire diameter even of the same size tire from one brand to another or even within a brand.

This is bad advice.

Even the big players in the game recognize this. I don't remember who, but one tuner company went as far as changing to a wider wheel front, narrower wheel rear to change handling characteristics of a certain tire while maintaining the same size all around because they simply did not want to run different sizes front to rear...

Well just talking from my experience . I ran stagger when I had awd on my IS which isn't a true 50/50 awd all the time. It a 30/70 split. Out of the the member still running stagger on awd IS have yet to hear any major issue. Beside the chosen the wrong tires size. Doesn't have to be completly on point on the diameter just within there giving 1%. If it was a major issue you be hearing it all over the IS forums. In other words should he no but can he yes.
