Abstract
The invention is directed to a valve stem system () for tubeless wheels. The valve stem system () includes a valve stem body () with a first end () and a second end (), wherein the second end () is located in a tire/rim-volume when mounted at the wheel. A first valve () is arranged at the second end () of the valve stem body (). The first valve () is a self-sealing one-way valve. A second valve () is removably mountable at the first end () and is, when mounted, at least partially housed in the valve stem body (). The second valve () comprises a valve stem core inserted in the valve stem body () and can be added or removed from the valve stem body () while pressure is maintained within the tire by the first valve (). The invention further concerns a probe () for a valve stem system, a method to test the amount of sealant in a wheel and a refilling assembly () for a wheel.
