RIDE, TRACTION & PERFORMANCE
Tires and Tractor Performance
To optimize tractor performance, tires should be selected
to suit the intended application. Key options like tire size
and cast weight packages, combined with proper tire
pressure, determine actual tractor performance.
Front Tire Selection
Choose the largest front tire or front dual option with
the highest weight-carrying capacity that matches the
row spacing. Selection of a larger tire results in reduced
compaction and permits heavier loads on the front axle
without exceeding the tire load-carrying capacity.
Rear Tire Selection
Choose rear tires that are large enough to carry the
total ballasted weight of the tractor with an inflation
pressure in the 6 - 14 psi range. Larger tires require
less inflation pressure to support a given axle load
than narrow tires do. Use only approved tire
combinations. The Lead/Lag should be between 0 -
5%, with a value of 1 - 3% being best. Negative
Lead/Lag is not recommended.
Lead/Lag
The relationship between the front and rear tires is
referred to as Lead/Lag and is stated as a
percentage. New Holland has established a
Lead/Lag range that provides the operator with
acceptable tire wear, front tire steering, and front
tire pulling power. Any tire combination that falls
within this range is acceptable. Lead/Lag
percentages can be calculated using the formula:
Interaxle Ratio - Front/Rear
*Front Axle Reduction Ratio
TG210 & TG230 (Standard).......................................................................................1.3228...........*21.525
TG210 & TG230 (TerraGlide)....................................................................................1.3228...........*21.525
TG210 & TG230 (SuperSteer) ...................................................................................1.3228...........*21.525
TG255 (Standard) .......................................................................................................1.3222...........*21.535
TG255 (TerraGlide) ....................................................................................................1.3222...........*21.535
TG255 (SuperSteer)....................................................................................................1.3222...........*21.535
TG285 (Standard) .......................................................................................................1.3250...........*21.535
TG285 (TerraGlide) ....................................................................................................1.3250...........*21.535
TG285 (SuperSteer)....................................................................................................1.3250...........*21.535
Note: *This ratio number (1) can be found on the axle serial number plate.
