Tire Combinations - 6175R to 6215R

IMPORTANT: If the tire combination or tire manufacturer is changed, the transmission ratio must be ascertained. See Calculate Tire Combination.

IMPORTANT: If the transmission ratio is to be changed, the following jobs must be performed by your John Deere™ dealer:

• Change the gear pair for the front-wheel drive axle output.
• Change tire size in the software of the control units
• Calibrate the radar (tractors with radar only)
