The \u003cstrong\u003eOPTIS (Odyssey Pneumatic Tire Insert System)\u003c\/strong\u003e is based on an independent inflatable insert, installed inside the tyre and maintained at a higher pressure than the tyre itself. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis design allows you to \u003cstrong\u003elower tyre pressure\u003c\/strong\u003e to gain grip and comfort on rough terrain, while maintaining excellent support thanks to the high-pressure insert. Odyssey recommends as a starting point reducing your usual tyre pressure by around \u003cstrong\u003e10%\u003c\/strong\u003e and inflating the OPTIS to approximately \u003cstrong\u003e25% above the desired tyre pressure\u003c\/strong\u003e. For off-road riding, the brand indicates that a pressure reduction of around 15% can also be considered depending on the rider and the terrain. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn the event of a heavy impact, the OPTIS also forms a \u003cstrong\u003epneumatic barrier between the tyre and the rim\u003c\/strong\u003e, reducing the risk of pinch flats and rim damage. At the same time, its pressure helps to hold the tyre beads against the rim, significantly reducing \u003cstrong\u003eburping\u003c\/strong\u003e and air loss during heavy cornering loads. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn the event of a puncture resulting in a total loss of tyre pressure, the insert temporarily continues to \u003cstrong\u003ehold the tyre on the rim\u003c\/strong\u003e. This run-flat function is designed to give the rider more control while slowing down and coming to a stop; Odyssey specifies that it should not be considered as allowing you to continue riding normally on a flat tyre. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFinally, unlike many foam inserts, the OPTIS is installed in a similar way to a \u003cstrong\u003estandard inner tube\u003c\/strong\u003e. During inflation, the insert also pushes the tyre beads outwards, making them easier to seat on the rim.
