New STS line – simple tubeless system – developed in 2016 by Marc-Ingegno sas, makes it possible to mount any type of tire from as tubeless with maximum safety and simplicity.

The new patented STS technology guarantees the rim, thanks to the containment shoulders specific for all kinds of tires, a perfect seal. If a puncture occurs, the maintenance is simple and fast; the tire may be replaced with an Allen wrench and inflated without the help of a compressor.

The rim has 3 components machined in ERGAL 7075: one central body unique per tire measurement and 2 modular shoulders, specific for each mounted tire.

In the aeronautical field mounting tubeless tires undoubtedly has at least three advantages: safety (less possibility of punctures), lightness (avoids the need of an air chamber weighing at least 300 grams), affordability (no need to buy the air chamber). But before our rims there were also issues: tires had to be mounted by specialized mechanics who had to insert the tire on the rim by deforming it with high pressure so as to find the correct position; if a puncture did occur, specific equipment was needed to bead break it from the rim; and forced to choose between a few types of specially produced “tubeless” tires.

With our rims, installation is very easy thanks to the dedicated shoulders. Tire do not have to be deformed. No compressors are needed. Maintenance is trivial and may be performed directly on the runway.
Every tire becomes tubeless, all in maximum safety.

Currently available in sizes: 5″- 6″ – 8″ . Size 4″ under development.
