Nooooo!
I blew one out a while back trying to change the tubes on some crappy tires that were really hard to get on/off. Sat fine for about 5 mins or so, but I guess the bead wasn't properly seated in one spot, and after a while the tube must have popped out and blown.
Come to think of it, I must still have those tires somewhere... if I can dig em up, I'll see if anyone on here wants em.
