Narrative:
During the walk around preflight; the captain noticed a large pressure difference between the #1 and #2 main tire pressures. #1 tire showed about 135 psi vs 205psi the tires had about a 70psi difference. Captain contacted maintenance control to report the problem. Control advised the two main tires would have to be changed. Flight was canceled and pilots waited until another company flight brought in new tires. We ferried the aircraft 10 hours later. Had the captain not checked the condition of the tires; who knows what could have happened. When were the tire pressures last checked on that aircraft?
