No offense taken -- I'm just working from the Schwalbe site; they include load ratings for different sizes of Big Apple, and the fatter the tire, the higher the rating. Here's where I got my info: http://www.schwalbetires.com/bike_tires/road_tires/big_apple
There's apparently a tradeoff between wheel strength and tire strength; my understanding is that smaller (spoked) wheels are stronger than larger ones, but larger tires appear to be stronger (carry larger loads) than smaller ones.
Back when I ran 700c, I did bottom out a 32mm (1.25") tire to the point that I rumpled the rim. Fortunately, disk brakes, and I could fix it with vise-grips, but not a really great thing to have happen.

Many weeks, maybe months. I suspect that Slime would also work better in the larger, lower-pressure tires, just because of the lower pressure pushing goop through holes..
