Top 10 Maintenance Tips For Aircraft Tyres

Top 10 Maintenance Tips For Aircraft Tyres

Preventive maintenance of tyres and proper tyres inspection can save lots of maintenance costs and increases the life of tyres. For the reason that here I’m discussing 10 easy ways to improve tyre performance and protect against wear.

Maintenance Tips To Improve Tyre Performance

1. Check tyre inflation pressure daily

Daily pressure checks are critical because aircraft tyre assemblies can lose as much as 5% of inflation pressure in 24 hours. Before placing wheel assembly into service, perform a 24 hours pressure retention check to ensure that the wheel assembly is holding pressure properly. Aircraft tyre pressure must be checked when the tyres are cool (at ambient temperature) because the heat generated during taxis, takeoffs and landings can result in elevated pressure readings. Always allow 2 hours of cooling time.

2. Remove tyres that are more than 10% underinflated

Under-inflation greatly increases tyre stress in service, wearing the tyre shoulder area faster and damaging the tyre inner liner.

3. Avoid Over Inflation of Tyre

As it often leads to uneven tread wear and reduced traction, making the tread area more susceptible to cuts and placing greater stress on aircraft wheels and landing gear.

4. Wait 12 hours before putting new tyres in service after initial inflation

All tyres will stretch after the initial inflation, causing a volume increase and thus a drop in pressure. Tyres should not be placed in service until they have been inflated for a minimum of 12 hours. The tyre pressure should then be checked and inflate the tyre, if necessary.

5. Recheck inflation after 24 hours

After the 12 hours stretch period to make sure the assembly is still holding inflation properly. This is especially important for tubeless assemblies because they can lose pressure from multiple locations, such as the wheel valve, o-ring, fuse plug, overpressure plug, wheel cracks and similar areas.

6. Minimize vibration with proper tyre and wheel assembly

All tyres are balanced at the factory. The red balance dot on the sidewall is to be aligned with the inflation valve for optimum tyre and wheel assembly balanced with less vibration. Gear misalignment, worn or loose gear components, improperly torqued axle or wheel nuts, flat-spotted tyres, and similar problems can cause vibration on an aircraft.

7. Avoid the No. 1 cause for early tyre removal – Foreign Object Damage

By diligently clearing all foreign objects from ramps and hangar floors, damage due to foreign objects can be reduced. Even something as innocuous as a washer can cut a tyre that is under heavy load.

8. Remove damaged tyres if fabric ply cords are visible

If cords are visible or cord exposure exceeds acceptable limits, the tyre should be removed. Cuts, cracks and other conditions may require removing the tyre from service.

9. Examine tyres for uneven wear and correct the cause

Such as gear misalignment or improper tyre inflation. Tyres with camber induced asymmetric wear can be demounted and mounted in the reverse direction to extend the life of the tyre.

10. Remove tyres when the tread is worn to the base

Tred wears to base or of any groove at any spot or to the depth stated by the aircraft manufacturer. This requires removing the tyre from aircraft.

  1. You made a great point about removing damaged tires if their fabric ply cords are visible beyond acceptable limits. My husband is a pilot and often doesn’t really know what maintenance happens. He will keep these tips in mind for the future as he gets more aircraft tires for his personal plane.
