Finabel is a European army interoperability organisation, and "Finabel testing" refers to the run-flat trial described in its agreement on combat tyres.
Suppliers quote Finabel often. This guide explains what it is and how a buyer should check a claim.
What Finabel is
Finabel describes itself as promoting and facilitating interoperability between land forces, by harmonising military concepts, doctrines and procedures. Today it calls itself the European Army Interoperability Centre, and it is based in Brussels.
It dates back to 1953. The name began as FINBEL, from the founding countries of France, Italy, the Netherlands, Belgium and Luxembourg. The A was added in 1956 when West Germany joined. The organisation is controlled by the chiefs of staff of member armies.
Finabel is an army organisation, and its agreements were written for military vehicles. We could not find a public Finabel list of approved run-flat products, or a public Finabel certification scheme. So treat "Finabel certified" as a claim to check, and ask who ran the test and who witnessed it.
What the agreement covers
The run-flat trial sits in Finabel Agreement 20.A.5 on combat tyres. It was written for military vehicles, and more than one edition has circulated over the years. Figures quoted for it can differ by edition, so ask for the current document from your own defence authority or from the supplier, and read the exact speeds, distances and deflation method there.
What this means for buyers
Finabel trials describe combat vehicles. Their results do not automatically apply to your vehicle, your load or your tyres. A result on one vehicle and wheel size does not prove the same result on another.
The trial is also a high bar for a specific task. A road ambulance or a family car does not need this kind of range. Road safety bands are designed for a shorter job and are tested differently. Tyron's Multiband, for example, was TÜV tested on a range of vehicles for 3 km at 80 km/h plus a further 3 km at 50 km/h through a handling course and slalom. That is a different job from a combat trial, so the two results should not be compared.
What to ask a supplier
If a supplier says a product meets Finabel, ask for:
- The current test document, and the edition they tested against.
- The full test report, with the date.
- The name of the test body and any government or military witness.
- The vehicle, gross weight, wheel, tyre size and insert used.
- The speeds and distances actually achieved, and how many tyres were deflated.
- How the tyres were deflated, and whether that method matches the current document.
- Whether the result applies to your vehicle, or whether a new test is needed.
Finabel and Tyron's range
Tyron's Finabel references relate to its heavier systems. R4, R6 and R7 wheels with an ATR rubber runflat are designed to give the beadlock needed to meet Finabel standards. Our guide to run-flat inserts explains how these parts work together. For test documents relevant to your vehicles, make a fleet enquiry.
