Narrative:
I was accomplishing a # 3 maintenance visit check on a B737-700 aircraft [on graveyard shift] that needed the #1; #2; #4 main landing gear (medium large transport) tires changed. I finished up the exterior parts of the aircraft. I did not check the tire pressures at that time knowing that I had three tires to be changed; I would check them after the new ones were installed and to let the other tires cool off [nose tires and # 3 main]. A co-worker and I changed the tires and went on to work other things on the aircraft that took us some time to get thru; then we went in and finished up the paperwork. I had to come back to the aircraft a few times to complete [items] that the maintenance visit check said to do. Then went on to help other aircraft maintenance technicians (amts) get finished on their aircraft. I missed checking the tire pressures and I don't know if my co-worker checked them after we changed them. Six legs after tire change; tire or tires came apart. I think that my coworker and I being new hires and trying our best to get the check done and the other maintenance task in a timely manner and help other people that needed help was a factor; and I did not stress to my co-worker that they [tires] need to be checked first! Or at least remind each other to check them - was a factor. [Suggest] that when I sign for something on the paperwork that I make sure it is completed and that I communicate better with the people I am working with.
