A short-lived series from the '80s with "Monster Trucks", which are actually normal vehicles with oversized tires. Most are actually normal 1-75 series models but they had different finishes and sometimes other additional parts such as motors or roll bar added. And of course the monster tires! However, there were a few completely new models, the "Monster Tractors', in this series. Due to the short production time most are difficult to find today.
