Claim Text:
1. A method of controlling a tire inflation system comprising: checking an inflation pressure of a tire; categorizing a type of pressure drop of the tire when the inflation pressure is less than a target tire pressure; inflating the tire when the inflation pressure of the tire is less than the target tire pressure; and adjusting a tire pressure sampling interval based on the type of pressure drop, wherein the type of pressure drop is a minor pressure drop when the tire is inflated to the target tire pressure within a threshold inflation time, the type of pressure drop is a moderate pressure drop when the tire is inflated to the target tire pressure and a time to inflate the tire to the target tire pressure exceeds the threshold inflation time, and a driver is alerted when there is the moderate pressure drop, but is not alerted when there is the minor pressure drop.
