The two small dual tire adapters by Bruder serve as functional connectors for compatible toy vehicles and tractors. Made of robust black plastic, the cylindrical sleeves allow for easy retrofitting of dual wheels. Precisely positioned retaining lugs and locking teeth ensure a form-fitting connection directly on the rims. Assembly and disassembly are completely tool-free. The additional tires noticeably increase the wheel contact area, which reduces sinking into soft ground such as soil or sand and noticeably improves tipping stability during play.
