275/65 fit fine with minimal scraping.
The only small issue is the rear wheel arch which has a small section jutting out (seen easily with the wheel on) which I add. covering the plastic sheild over the fuel tank filler pipe.
It has an inch of play and you simply whip the wheel off, heat up the wheel arch plastic, then push it in while cooling. BINGO.
