Seven Tips to Extend Tire Life and Save You Money

Correct tire pressure is a measure of tire size and the axle load. With those, inflation tables (or the Firestone Tire Pressure Calculator at calculate the correct minimum inflation pressure to carry the load.

There are ways to fend off stubble damage. Drive at angle to the row, not directly down the row, is one. Another is tread design. Firestone manufactures tires with a “stubble deflector” tread design — the tread pattern pushes the stubble aside similar to a cowcatcher on a train.


Firestone offers other suggestions for extending the life of agricultural tires.

1. As much as 40% of engine power is lost through rolling resistance and slip. Check tire pressure with a calibrated gauge and set the inflation pressure using a pressure calculator. Inscribe the correct inflation pressure in permanent marker near the inflation valve. Correct pressure gives the tire a larger footprint, reduces slip, reduces fuel usage, limits soil compaction, reduces equipment wear and provides a smoother ride.

2. Unlike a human cut, a tire doesn’t heal itself. Check the tire sidewalls for cracks, cuts, and other damage. If you see cords, it is time to shop for new tires.

3. Check tire treads and consider replacing if there is less than 20% left. At that point, tires are slipping, and fuel efficiency is taking a hit.

4. A 15-minute tire pressure check during refueling can prevent downtime. Check tire tread areas for stubble damage and exposed cords. Replace tires with obvious damage.

5. Check ground contact for gaps between the bar and the ground. If you can put your finger under the bar at the 6 o’clock position the tire, the tire is probably overinflated.

6. Check valve stems for cracks, corrosion, and debris. Make sure the caps are clean and intact and returned onto the stem.

7. Check nuts, bolts and wheel weights to ensure they are torqued correctly.
