The John Deere 6500L uses 9.5-15 on both the front and rear in this data, so the same tire-size details apply to both axles: bias/imperial tire, 9.5 in section width, 15 in rim
Ballast note
For the John Deere 6500L rear 9.5-15 tires, the ballast figure captured in the answer is 6,500 L. Liquid ballast capacity can change by tire brand, fill percentage, wheel setup and ballast fluid type
Front/rear matching note
The John Deere 6500L data shows the same tire size front and rear (9.5-15). 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.
