Narrative:
[A coworker] and myself were taken to taxi aircraft from gate. On my pre-taxi walk around I found number 2 medium large transport tire underinflated. I told [coworker] I would address it accordingly. I called terminal maintenance and I requested that they send out a mechanic to verify tire pressure. A mechanic whom I don't know took the pressure and stated it was only 60psi. [A coworker] went down and said he wanted to re-service the tire to service limits. [Another coworker] said that was against general procedures manual (gpm) and unsafe and that both tires should be changed. I called tech and spoke with them on the desk to see what my options were. They also stated that both tires had to be changed. When I went from the cockpit to tell the mechanics this I discovered that they had re-inflated the tire to service limits. I [told] them both (whom I don't know their name) that now they had as 'bomb'. I asked them why they would do that and they stated they were told to do so. I called and explained what occurred and requested to be reassigned to a different aircraft. Upon pushback the no.2 tire which was re-inflated to service limits exploded after just moving a few feet.this occurred because of the management's insistence that the aircraft is to be removed off the gate at all cost to prevent delays. This was an easy fix.gpm states that if one tire is below limits both tires should be removed and replaced.. Periodwhy is this type of disregard for policies and procedures that we have in place for retention of our operating certificate from the FAA be so disregarded for the profitability of the shareholders and upper management is a recipe for the ultimate betrayal for the common employee let alone the passengers if the exploding tire killed the mechanic servicing it could be called justified...if the exploding tire killed another mechanic it would have been homicide...

Title: On a B737-800 a #2 Main Landing Gear tire exploded because it was found underinflated and it was inflated instead of following the maintenance manual which required replacement both #1 and #2 tires.
