John Deere 9220 Extra Tire Notes
Tire size note
The John Deere 9220 uses 620/70R42 on both the front and rear in this data, so the same tire-size details apply to both axles: metric radial, 620 mm section width, 70% aspect ratio, 42 in rim, approx 76.2 in overall diameter
Front/rear matching note
The John Deere 9220 data shows the same tire size front and rear (620/70R42). That usually makes the visible front/rear size relationship simpler, but approved tire and wheel combinations should still be checked before mixing brands or changing sizes
Official information note
Mistakes do happen. Tire sizes can change by year, axle, wheel/rim option, tyre brand, tread type and local market. Please check the tire sidewall, operator manual and official deere.com website for official information.
