Rolling Resistance Measurement Procedure for Passenger Car, Light Truck, and Highway Truck and Bus Tires
- Ground Vehicle Standard
- J1269_198511
- Revised
Scope
This SAE Recommended Practice applies to the laboratory measurement of rolling resistance of pneumatic passenger car and light truck tires.
The procedure applies only to the steady-state operation of free-rolling tires at zero slip and inclination angles; it includes the following three basic methods:
Force Method--Measures the reaction force at the tire spindle and converts it to rolling resistance.
Torque Method--Measures the torque input to the test machine and converts it to rolling resistance.
Power Method--Measures the power input to the test machine and converts it to rolling resistance.

Issuing Committee
To plan and execute a cooperative tire test development program, to evaluate the fatigue endurance performance of light duty highway tires. Activities will include empirical comparisons of tire performance on the various, proposed tests, together with evaluating reasonable relationships to tire usage and durability performance on the highway.
