Abstract: A multi-chambered tubeless tyre or tube and manufacturing process for the same for vehicles comprising of a master chamber near wheel rim to keep/contain pressurized air/fluid; at least one chamber sandwiched between said master chamber and inner surface of tyre, said sandwiched chamber(s) has/have independent one way inlet valve for sealant or pressurized fluid/air as the case may be; said sandwiched chamber(s) are formed and joined in green state with said green tube or green tubeless tyre to achieve mechanical properties after vulcanization. Even independent chamber can be sandwiched between said master chamber and inner surface of tyre. This arrangement can be used in all kind of vehicles. It can be used in Self Supporting RFT (Run Flat Tyres), Auxiliary Supported RFT. It can be used for replacement of twin tire by providing extra wide tyre with multiple chambers with/without sealant.
