Abstract
In a method and an apparatus for testing a pneumatic tire such as for testing the uniformity thereof, a tire to be tested is inflated to a given pressure and rolled against a test surface at a tire contact patch, and forces and/or moments acting at the contact patch are measured. To at least reduce the period of time required for the tire to warm up for a testing operation, the compressed air used to inflate the tire is heated to a given temperature before being passed into the interior of the tire. The compressed air may be heated as it flows through a supply conduit, under the control of a sensor for sensing the temperature in the tire.
