Load Capacity of Tires, Front Axle Load

Comply with maximum front axle load (see ”Loads and Weights”).

Depending on the make of tire, permissible front axle loads may be limited to figures below those quoted here. Permissible loads are indicated by the weight-and-speed index. For details, ask your John Deere dealer or the tire manufacturer's agent.

On leaving the factory, tractors with front-wheel drive may be equipped with the following front tires:
