John Deere 9470R Extra Tire Notes
Tire size note
The John Deere 9470R uses 20.8R42 on both the front and rear in this data, so the same tire-size details apply to both axles: imperial radial, 20.8 in section width, 42 in rim
Front/rear matching note
The John Deere 9470R data shows the same tire size front and rear (20.8R42). 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.
