ASTM F2869 – Standard Practice forRadial Light Truck Tires to Establish Equivalent Test SeverityBetween a 1.707-m (67.23-in.) Diameter Rotating Roadwheel and a FlatSurface
1.1 This practice describes the procedure to identify equivalent test severity conditions between a 1.707-m diameter laboratory roadwheel surface and a flat or highway surface for radial pneumatic light truck (LT) tires.
1.1.1 Tire operational severity, as defined as the running or operational temperature for certain specified internal tire locations, is not the same for these two test conditions. It is typically higher for the laboratory roadwheel at equal load, speed and inflation pressure conditions due to the curvature effect.
