What tire load index 57 means

Load index 57 corresponds to a reference maximum mass of 230 kilograms (507 pounds) for one tire under the conditions defined by the applicable tire standard. It is not the vehicle's payload rating.

Replacement safety

Use the vehicle manufacturer’s placard and owner documentation. Size, load capacity, pressure, speed capability and axle requirements must all be verified; never select a replacement from this number alone.
