Sir, guys of our weight need custom wheels, at least the rear, especially when you're talking narrow rims. You can slow down the failure rate by going to a wider tire @ less pressure for a softer ride, but most bikes with rims like yours don't have brake or frame room for bigger tires.
Most of your weight is on the rear wheel.
Most bikes with rims like yours are designed for 150-165lb riders.
The last failed wheel I've had is a 26 (559)x25mm at 908.8miles. I'm riding a spare wheel while I arrange a rebuild.
I suggest a 36hole hub minimum. About $260ish should get you a custom wheel with an entry grade shimano hub (or just use your hub) & a hellaciously strong Velocity rim from Peter White. (Extremely grumpy sometimes). He has a great deal of experience with bicycle & wheel weight capacity. Make sure you read the "wheel rant" section.
