How long do aircraft tyres last before replacement?

Aircraft tyres are replaced on condition, not after one universal number of flights. In real-world aviation, an airliner tyre commonly lasts a few hundred landings, while training and light-aircraft tyres vary far more. Maintenance limits, pressure history, damage and tread wear—not calendar age alone—determine removal.

Is there a fixed aircraft tyre replacement interval?

No fixed interval applies to every aircraft tyre. For a large transport aircraft, roughly 200–400 landings per tread is a useful order-of-magnitude estimate, but individual tyres may be removed much earlier or remain serviceable longer.

Landings are more meaningful than flight hours because touchdown, wheel spin-up and braking cause most tyre wear. A short-haul airliner can therefore consume tyres faster in calendar time than a long-haul aircraft that flies many hours per cycle. Training aircraft doing repeated circuits and touch-and-go landings may also wear tyres quickly despite accumulating relatively few hours.

Light private aircraft can retain the same tyres for several years when flown infrequently. In that case, age-related cracking, flat spotting and pressure loss may become the limiting factors before the tread is worn out. Any calendar or storage restriction in the aircraft maintenance manual, maintenance programme or tyre manufacturer’s instructions takes precedence.

The figure also depends on which wheel is being considered. Main-gear tyres carry the major touchdown and braking loads, while nose tyres experience steering scrub, shimmy and towing loads. Our explanation of how landing gear absorbs touchdown and braking loads covers the wider system around the tyre.

What shortens aircraft tyre life?

Incorrect pressure, abrasive surfaces, heavy braking and tyre scrubbing are the main causes of shortened aircraft tyre life.

• Incorrect inflation pressure: Underinflation causes excessive casing flex, heat build-up and shoulder wear. Excessive pressure can concentrate wear around the centre of the tread and reduce the tyre’s ability to absorb surface irregularities. Pressure must be checked under the conditions specified by the maintenance data; a hot tyre immediately after flight gives a misleading comparison with a cold-pressure limit.
• Hard landings and braking: High touchdown speed, locked-wheel skids, crosswind side loads and aggressive braking remove rubber rapidly. A rejected take-off or overheated brake can trigger a specific inspection even if the tread still appears usable.
• Runway and taxiway surfaces: Coarse or grooved pavement improves grip and drainage but can increase abrasion. Stones, metal fragments and other foreign-object debris can produce cuts during taxi or while the aircraft is in areas used for parking and movement on the airport apron.
• Tight turns and poor alignment: Pivoting a loaded aircraft, nose-wheel shimmy, incorrect wheel alignment and repeated tight turns scrub the tread sideways. During towing, exceeding the permitted nose-wheel steering angle can damage tyres or steering components; the risk is explained in our guide to steering limits and ground-crew roles during pushback.
• Heat and high loads: Heavy aircraft weights, fast taxiing and repeated braking increase tyre and wheel temperatures. Approved loading, speed and cooling restrictions are therefore part of tyre protection, not merely brake management.

The mistake we see most often is judging tyre life solely by visible tread depth. A tyre with substantial tread can still be unserviceable because of casing damage, a bulge, pressure loss or heat exposure.

How do maintenance crews know when a tyre needs replacing?

Maintenance crews compare the tyre’s condition with approved wear and damage limits rather than relying on appearance alone.

• Tread wear: Remaining groove depth, localised wear and any exposed reinforcing material are checked against the applicable maintenance limits. Uneven wear can point to inflation, alignment or braking problems that must also be corrected.
• Cuts and casing damage: Cuts, embedded debris, sidewall damage, bulges, tread separation and skid burns are measured and assessed. A conspicuous tread cut may sometimes remain within limits, while a smaller sidewall defect may require immediate removal.
• Pressure loss: Repeated or excessive pressure loss can indicate a leaking valve, wheel seal or damaged casing. Simply reinflating the tyre without finding the cause is not an adequate fix.
• Abnormal events: A rejected take-off, hard landing, burst tyre, brake overheat or towing excursion may require an inspection defined by the aircraft manual. On multi-wheel landing gear, a companion tyre may also need inspection after another tyre loses pressure because it may have carried an excessive load.

Airlines normally change the complete wheel-and-tyre assembly on the aircraft, then send it to a workshop for separation and inspection. Tyres do not necessarily have to be replaced as a complete set, although limits on matching, pressure and dimensional differences may apply to adjacent wheels.

Can aircraft tyres be retreaded and used again?

Yes, many commercial aircraft tyres are retreaded several times when their casings pass the required inspections.

Retreading replaces the worn tread; it does not make a damaged casing serviceable. The casing is inspected for impact, fatigue, heat and structural damage, and it is rejected when it fails the approved criteria. The permitted number of retreads depends on the tyre design, casing condition and applicable maintenance data.

This distinction explains some apparently conflicting lifespan figures. A tyre may provide only a few hundred landings on one tread, while the same approved casing accumulates a much larger total across several retreads. For operational planning, tread life, casing life and calendar age must therefore be recorded and considered separately.
