John Deere Z925M Extra Tire Notes
Tire size note
The John Deere Z925M uses 13×5-6 on both the front and rear in this data, so the same tire-size details apply to both axles: flotation/implement tire, 5 in section width, 6 in rim, approx 13 in overall diameter
Pressure note
For the John Deere Z925M with front 13×5-6 and rear 13×5-6 tires, the pressure values captured in the answer are 14 PSI, 10 PSI. Tire pressure is load-dependent, so use this as a reference value rather than a universal setting
Front/rear matching note
The John Deere Z925M data shows the same tire size front and rear (13×5-6). 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.
