Wood Collector,
I checked out the rope you were looking at. There is nothing in the listing showing the manufacturer's name, nor any rating specifications. I'm all but sure that the rope in question is a cheap import.
You'll need to decide if this rope will get you by until such time as you can earn enough money to buy a rated rigging rope made by a reputable company. You could always use the unrated rope as a tag line or haul line, although it would be a bit large for those duties.
Your pulley likely has a relatively long axle, as you say it is capable of handling larger diameter ropes. If your side plates are spaced far apart, the axle may bend, or be seriously stressed. Over time, a stressed axle will crack and fail.....and usually at the most critical moment.......when it's under load.

I am sure it will be fine to use in a tree but how long it will last I am not sure. I like to follow a 1/10 working load to breaking load in all of my tree work.
