Why Tire Pressure Matters
Here’s why checking and adjusting tire pressure regularly is so important:
- Even Cutting: Uneven tire pressure can lead to uneven deck height, causing scalping or missed patches.
- Better Traction: Properly inflated tires maintain consistent ground contact, improving traction.
- Operator Comfort: The right pressure absorbs shocks better and leads to a smoother ride.
- Longer Tire Life: Underinflated tires wear out faster and are more prone to sidewall damage.
- Fuel Efficiency: Balanced tires reduce rolling resistance and engine strain.
General Tire Pressure Guidelines
Before diving into the specific chart, here are the general tire pressure recommendations:
- Front Caster Wheels: 22–25 PSI
- Rear Drive Tires: 10–14 PSI
However, specific pressures may vary slightly depending on the model, deck size, and tire size.

Common Tire Pressure Mistakes to Avoid
- Overinflation: Leads to rough rides and reduced traction.
- Underinflation: Causes premature wear, poor cutting, and possible tire failure.
- Mismatched pressures: Uneven tire pressure side to side leads to uneven cutting height.
Tire Pressure and Deck Leveling
Incorrect tire pressure affects deck leveling, which can make your mower cut higher on one side. Before adjusting your deck, always:
- Set tires to the recommended PSI
- Measure tire height from the ground
- Then level the mower deck
