Abstract
A method of determining whether a tire will satisfy a t hour pressure retention standard in about x hours, where x is less than t, that involves determining a tire pressure stabilization time z (120), inflating a tire at time t0 to a first pressure (122), taking a first pressure measurement at (x-y) hours after t0 where (x-y).gtoreq.z (124), taking a second pressure measurement at x hours (126), determining a change in pressure between the first pressure measurement and the second pressure measurement (128) and determining from the change in pressure whether the tire will satisfy the t hour pressure retention standard (130).
