The tire pressure detector and valve stem assembly has a valve stem, a wireless pressure detector and a fastener. The valve stem has an outer section and an inner section. The inner section is integrally and coaxially formed on the outer section and has a distal end, an outlet hole, a sidewall and at least one clamping surface. The at least one clamping surface is flat and is tangentially formed on the sidewall. To assemble, only a regular tool such as a clamp or a spanner is necessary to clamp the inner section on the clamping surface when mounting or dismounting the valve stem onto or from a rim.
