John Deere 3025E R1 Ag Tire Size
The R1 agricultural tire setup for the John Deere 3025E uses 7-14 front tires and 11.2-24 rear tires. This is the best tire style for dirt, loose soil, gardens, field traction, and work where grip matters more than lawn protection.
Best bite in soil, mud, loose ground, and farm-style work.
John Deere 3025E R3 Turf Tire Size
The R3 turf tire setup for the John Deere 3025E uses 27×8.5-15 front tires and 41×14-20 rear tires. This is the lawn-friendly package for mowing, turf work, estates, parks, and owners who want less grass damage.
Grass-friendly rear traction with lower turf damage than R1 or R4 tires.
John Deere 3025E R4 Industrial Tire Size
The standard R4 industrial tire setup for the John Deere 3025E uses 25×8.5-14 front tires and 15-19.5 rear tires. Deere also lists a larger R4 setup using 27×8.5-15 front tires and 43×16-20 rear tires. R4 tires are the popular all-rounder for loader work, gravel, dirt, snow, and mixed property use.
All-round durability and traction for general property work.
Larger Front R4 Industrial
27×8.5-15
Larger R4 package listed by Deere; verify wheels and fitment before swapping.
Larger Rear R4 Industrial
43×16-20
Larger R4 package listed by Deere; replace as a matched front/rear set only.
Blunt verdict: do not mix random 3025E front and rear tire sizes. This is a 4WD tractor, so rolling circumference matters. Wrong combinations can cause driveline bind, tire scrub, poor steering, and expensive wear.

Best Replacement Tires for a John Deere 3025E
The best replacement tire for a John Deere 3025E depends on the job. Use R1 Ag if you need maximum bite in soil. Use R3 Turf if you mostly mow or protect grass. Use R4 Industrial if you do loader work, gravel, dirt, snow, and general property maintenance.
Larger industrial setup only if wheels and tractor fitment match.
Owner tip: if you are changing from turf to industrial or ag tires, do not just buy four loose tires. You may need different wheels, and the front/rear rolling ratio must stay correct.
R1 vs R3 vs R4 Tires on a John Deere 3025E
R1 Ag
Best for dirt, soil, garden work, mud, field bite, and maximum traction. Worst for finished lawns.
R3 Turf
Best for mowing, lawn protection, parks, estates, and lower turf damage. Weakest for mud and loader abuse.
R4 Industrial
Best all-rounder for loader work, gravel, snow, dirt, and property maintenance. Can mark lawns more than turf tires.
John Deere 3025E Tire Pressure
John Deere 3025E tire pressure is not one universal number. It depends on tire type, loader use, ballast, wheel weights, tire brand, ply/load rating, sidewall limit, and whether the tractor is used for mowing, loader work, soil work, or road travel. Use the operator manual, tire sidewall, and tire manufacturer’s load chart for your exact tire.
Use Case
Pressure Guidance
Why It Matters
Mowing with R3 turf tires
Keep left and right pressures equal and within tire/manual guidance
Uneven tire pressure can affect mower cut quality and turf marks.
Loader work with R4 tires
Front tires may need more pressure within tire limits
Loader weight puts extra load on the front axle and front tires.
R1 field work
Use tire load chart and avoid overinflation for traction
Correct pressure improves bite and reduces soil compaction.
Ballasted rear tires
Check pressure after adding liquid ballast or wheel weights
Ballast changes sidewall deflection and tire load.
Real-world fix: if the 3025E feels unstable, rides rough, spins easily, or cuts unevenly, check tire pressure and ballast before blaming the tractor.
John Deere 3025E Tire Chains
Rear tire chains for the John Deere 3025E must match the rear tire size. Common chain targets are 11.2-24 for R1, 41×14-20 for R3 turf, and 15-19.5 for the standard R4 package. For the larger R4 package, use chains sized for 43×16-20.
