You did not mention rim size, so I will assume 700C. I run 26" rims just to be compatible with my wife, but 26" are allegedly stronger than 700C due to the shorter spoke length. Also, I ride a Surly Disc Trucker with front and rear racks. It is a tank, weighing in at around 39 lbs with racks. We are also using the TransAm Eastern Express which uses around 600 miles of rail-trail, so we are running gravel part of the way.
I weigh around 210, but I tear up wheels, so I have been building my own. However, I just had a set built for my TransAm tour, since the wheel builder,
Prowheelbuilder.com, had parts I could not get. They also have a wheel build planning tool. I included my wheel build specs below.
The cross patterns of your spokes also adds wheel strength. The builder recommended 4-Cross but I went with 3-Cross, which they agreed was fine for a 26" wheel.
I have the Ortlieb Classic Roller Panniers - full waterproof and the front (smaller ones) weigh about 8 pounds loaded and the rears around 9 pounds each - that includes the weight of the pannier. I also have their 6L handlebar bag with probably weighs in at 10lbs. loaded. I only have Crocs on my rack which I think weigh 14 oz. A full 26 oz. water bottle weighs in just under 2 lbs. so remember to count those.
For tires I am running Surly Extraterrestrials 26 X 46 tubeless. Schwalbe does not make a 26" tubeless. I am carrying a Tublito spare tube(s) at 1.5 ounces for emergences. I find the Extraterrestrials to ride okay, but they seem loud on pavement compared to other tires. If you are new to touring tubeless may not be a good option for you since it is one more thing to master.
