Tire Pressure & Wheel Size for John Deere Lawn Mowers

Understanding Your John Deere  Lawn Mower Tire Pressure

Proper tire pressure is really important for your John Deere lawn mower to ensure a smooth ride, even cutting performance, and safe operation. Under-inflated tires can cause uneven cutting, poor traction, and increase wear on the tread. Over-inflated tires can make the ride rough and may wear the tread unevenly.​

  • For most John Deere riding lawn mowers, the recommended tire pressure is typically:

    • Front tires: 12–14 PSI

    • Rear tires: 8–10 PSI

  • Always refer to your specific model's operator manual and check the tire sidewall for exact recommendations.​​

Check your tire pressure before each use with a reliable gauge. Tire pressure can change with temperature and over time, so regular checks help keep your mower operating as intended.

​

Why Is Correct Tire Pressure Important?

  • Tires that have the correct pressure will provide a more even and level cut across your lawn

  • Protects your yard by preventing ruts and turf damage.

  • Improves fuel efficiency and overall mower performance.

  • Extends the lifespan of your tires.​

  • Front Tires: Typically range from 13x5-6, 15x6-6, or 16x6.5-8

  • Rear Tires: Often 18x8.5-8, 20x10-8, or similar

Always confirm your tire and wheel size by checking the model number, the tire sidewall, or referring to the compatibility chart found in your owner's manual or equipment support resources.​
