In principle, you would want the front at about 2/3rd the pressure of the rear (for static riding).
During aggressive braking, your weight shifts significantly forward, so if the front tire pressure is too low, it will wallow and handling suffers. So there's a trade-off between static riding comfort and aggressive handling.
Personally, I run my front about 15% lower than the rear, but I tend to ride fairly aggressively on most bikes. You can experiment by lowering the front pressure in 5 psi increments.
to the fellow asking the question"--- this pretty much sums it up. I weigh a good 80lbs less than you so my pressures have no connection to yours and I haven't a clue, but lower front pressures are standard procedure.
if you don't have one, but yourself a floor pump with gauge, and start trying different pressures.
Proper pressures , not too high, will be more comfortable and faster for a wide variety of road surfaces.
I commute all the time and for years have done pressure tests over a repeating route, and it's proven to me that proper lower pressures are as fast or faster, and way more comfortable than max pressures, while putting out the same power.
