Tire Load Index
IMPORTANT: Tire load capacity may exceed allowable axle loading.
Tractor should be ballasted according to engine power and weight split
guidelines. See Performance Ballasting Section in this Operator’s
Manual for more information.
Tire industry uses a number called “load index”
to define load rating of a tire. This chart lists, for a given load
index, maximum amount of weight that can be supported by each tire
at manufacturer’s maximum rated pressure.
Load carrying capacity per tire is reduced for tractors equipped
with duals and triple.
