1) If the tire is rated at 100 psi, you need to put close to 100 psi. Use more pressure for a heavy load, less for a lighter load. Underinflation is the most common cause of tire/tube failures.
2) A tire blowing off the rim is commonly due to improper installation.
3) The smaller tube was not the problem.
