I'm not sure if I'm going to fix it again soon, the allure of repairing yet another series of flats like I did a couple of years ago combined with the increased hassles of traffic I've been dealing with may get me to find some other way to get my exercise for a while.
it's not the tire being wide, it's the tire being thick (plenty of rubber) that helps.
you shouldn't continue riding on the bike with the tire deflated as you can damage the tire.
a wheel with no more than 500g rim weight can be built to sustain up to 400kgf dynamic load. the tire will be more vulnerable than the rim.
but you should not go with very high tension on normal length and with thin spokes, large spoke tension variance etc. etc.. the wheel is to have NDS approach zero tension when reaching it's maximum load (it's limitations) and not remain at a considerable tension because the spokes tension is added to the external load and that is just one argument against excessive tension.
except few people are able to figure out what excessive tension is for all the parameters of one certain wheel.
