Some tire sidewalls state up to 51psi max (especially on larger, wider tires - like those on many 17" rims).
My standard Dunlops are 44psi max. Whatever was put in at the dealership is what is in them, and I haven't checked yet (I've had the car only three days). I suspect they're at 32 or so, though.
