Abstract
Pneumatic tire having an integral inflation indicator in the form of interdigitized groups of raised mesas affixed to the sidewall of the casing on opposite sides of the centerline of the sidewall. The two groups pivot apart by flexing of the sidewall under load when the tire is under-inflated, and they tend to overlap at the centerline when the tire is over-inflated. Indicators carried by the mesas indicate by position the extent of under-inflation or over-inflation.
