Select a Method to Measure Tire Rolling Resistance in Order to Compare Tires

• SAE J2452 values at various speed, load, and inflations used to relate tire properties to vehicle – SMERF (Standard Mean Equivalent Rolling Force)

• SAE J1269 and ISO 18164 describe the tire response at various load and inflation conditions – SRC (Standard Reference Condition)

• SAE J1269 and ISO 28580 test a tire at standard conditions of speed, load, and inflation
