obtaining load data for a wheel of a vehicle;
obtaining speed data for the vehicle;
determining a power associated with heating a tire coupled to the wheel based on the load data and the speed data; and
determining a condition of the tire based on the power.
12. The method of claim 11 , further including determining if the power is greater than a threshold.
13. The method of claim 12 , wherein the threshold is an expected power for the load data and the speed data.
14. The method of claim 11 , further including indicating the condition of the tire via a display of the vehicle.
15. An apparatus comprising:
a vehicle steering sensor; and
a processor to:
obtain vehicle steering data of a vehicle, determine a power associated with heating a tire based on the steering data, and determine a condition of the tire based on the power.
16. The apparatus of claim 15 , wherein the processor is to determine a turning loss measurement based on the steering data.
17. The apparatus of claim 15 , wherein the processor is to obtain load data for a wheel of the vehicle and speed data for the vehicle.
18. The apparatus of claim 15 , wherein the processor is to determine if the power is greater than a threshold.
