C04Aircraft tires

Carry ground loads and provide the contact surface.

Manufacturers & products

Size, construction, ply rating and speed rating identify only part of a tire selection. The approved wheel, axle load, inflation schedule and aircraft effectivity also matter.

Program applicability is stated for each listing. 737NG, 737 MAX, and other aircraft examples are distinct configurations; listed products are not automatically interchangeable or approved for installation.

manufacturer

What remains unverified

  • The Dunlop narrative inconsistently prints H44 and H44.5; the example omits that ambiguous size pending a current part datasheet.
  • A current approved application list is needed to resolve specific aircraft weight and wheel options.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

  • Approved application and part number

    Confirm aircraft series, position and tire option in current approved documentation.

  • Size and rim interface

    Match diameter, width and rim specification; similar size text is insufficient.

  • Construction

    Radial and bias tires can require different approved wheel and operating configurations.

  • Load and ply rating

    Ply rating denotes a strength rating and should not be treated as an actual layer count.

  • Rated speed · mph

    Compare published tire speed ratings, not aircraft cruise speed.

  • Inflation and deflection · pressure

    Evaluate rated load at the specified inflation and test conditions.

  • Mass and operating durability · kg / landings

    Compare consistent new/retread state and duty rather than broad longevity marketing.

  • Retread and supply traceability

    Track casing eligibility, approved repair scope and manufacturer part records.

Selection & integration notes
  • MAX tire examples are explicitly labeled and must not be substituted for NG tire data.
