My 2 cents. I have a wheel on my tandem supporting over 400 lbs combined rider weight. But it a Deep V 48 tandem hub.
I rarely think riders need anything that strong but you at your weight, I'm not sure I would recommend a 36 spoke wheel. (others may chime in with experience).
I'd say the rear would need replacement soon after the purchase, if not at the tme of purchase.
The front takes less abuse so I'd say you would be ok for a while rebuild funds. That is if you aren't bombing down mountains at 40 mph with switchbacks.
You "MIGHT" get by with a 36 DeepV but again, someone at your weight would have to chime in with experience.
