This question has come up. Thought I would post this.
From Car talk website
"Bill says that over-inflation almost never causes tire failure. The standard tire is inflated to about 30 to 35 pounds per square inch. Under hot weather and highway conditions, the temperature of the air inside the tire rises about 50 degrees. That increases the pressure inside the tire about 5 psi. The burst pressure of a tire is about 200 psi. So unless you had your tires pumped up to 195 psi (trust us, you didn't), you didn't come anywhere near bursting the tire from too much internal pressure."
("Bill spent his career as a tire engineer, and now runs a company called TFI: Tire Forensics Investigation")
