Triangle Tyre Secures CAAC Approval for Aviation Tyres

Triangle Tyre has received China Civil Aviation Technical Standard Order Authorization for four civil aviation radial tyre part numbers after review by the Civil Aviation Administration of China. The company says the approval covers products developed for aircraft including China’s COMAC C919 and the Airbus A320, marking a significant move into a demanding specialist tyre segment.

A high-barrier tyre sector

The approval, granted on 11 May 2026, gives Triangle Tyre authorisation to design and manufacture the certified aviation tyre products and mark them with the relevant CTSO identification numbers. Triangle said the certification followed CAAC scrutiny of design and production conformity, including manufacturing, testing and quality controls.

Aviation tyres are safety-critical products. They must withstand high loads, high-speed rolling, repeated landings and demanding temperature conditions. Triangle said its certification process included static load testing, high-speed rolling tests and extreme-temperature performance assessments.

The company said the approval “reinforced the security and self-reliance of the aviation supply chain”. That claim should be viewed in context. CTSOA authorisation confirms compliance for the approved article, but separate aircraft-level approval may still be required before installation, as is typical with technical standard order authorisations. The UK Civil Aviation Authority describes comparable UKTSOAs as stand-alone equipment approvals rather than installation approvals.

Why it matters for tyre manufacturing

For the tyre trade, the development is relevant because it shows a Chinese tyre manufacturer moving further into advanced, regulated product categories. Triangle said the four approved part numbers were developed for leading aircraft models, including the domestically produced C919 and Airbus A320.

Triangle began dedicated aviation radial tyre research in 2017. Its programme has since covered framework materials, structural design, equipment development, simulation and airworthiness quality systems. The company also cites investment in a dedicated aviation tyre laboratory in Weihai and a full civil aviation radial tyre production line.

This technical direction sits alongside Triangle’s wider international activity. Tyre News recently reported on Triangle’s European growth plans for The Tire Cologne and its ESG priorities. It has also covered Triangle’s £360 million Cambodia plant, planned to add passenger car and truck and bus radial capacity for global markets.

From simulation work to certification

Triangle’s aviation tyre work has developed over more than a decade. In 2014, the company completed splash simulation analysis for tyres used on the COMAC ARJ21 regional aircraft, now known as the C909. In 2019, it expanded cooperation with COMAC on numerical simulation models for C919 main tyre dynamics.

The company’s 30×8.8R15 aviation tyre passed dynamic simulation testing in Xianyang in July 2020. Triangle later completed an aviation tyre laboratory in Weihai and built a production line for civil aviation radial tyres. The latest CTSOA approval now provides a regulatory milestone for the programme.

For aircraft manufacturers and tyre suppliers, the approval points to deeper localisation of aviation tyre capability in China. For the wider tyre industry, it also highlights how advanced materials, simulation, testing and quality systems are becoming central to specialist tyre production.

Triangle Aviation Tire Milestones

In October 2014, Triangle Tyre completed splash simulation analysis for tires for the COMAC ARJ21 regional aircraft (now C909), helping pave the way for the aircraft’s all-weather airworthiness certification.

In 2019, Triangle Tyre further expanded cooperation with COMAC, undertaking the research on numerical simulation models for the dynamic characteristics of main tires for the C919 aircraft.

In April 2019, the Triangle aviation tire project received approval support under Shandong Province’s Major Program for New and Old Kinetic Energy Conversion.

In October 2019, the “Large Aircraft Ground Dynamics Joint Laboratory”, initiated by COMAC, was established in Changsha, with Triangle undertaking the research on the “Tire Ground Dynamics” program.

In July 2020, Triangle’s independently developed 30×8.8R15 aviation tire passed dynamic simulation testing in Xianyang, becoming the first civil aviation radial tire product in China to achieve this milestone.

In September 2020, Triangle Tyre’s aviation tire laboratory, with an investment exceeding RMB 50 million, was completed and put into operation in Weihai.

In August 2021, Triangle Tyre built a full civil aviation radial tire production line in Weihai, passing project acceptance and establishing large-scale manufacturing capability.

In September 2022, the Triangle aviation radial tire project was awarded the Gold Award at the 4th “Governor’s Cup” Industrial Design Competition.

In May 2026, Triangle’s civil aviation radial tires passed the CAAC review and were awarded the CTSOA certification.
