Tyres for truck trial

Native Lego tyres have a smooth tread and this cause tyres can be the weakest link in the model. One of the good approaches is to use 94.8x44R tyres (54120) mounted on the Wheel Technic Racing (22969). Another good approach is to use tyres from RC-models such as RC4WD Mud Slingers or RC4WD Rock Crusher X/T. These tyres can be mounted on the Wheel 68.8x36ZR (44772).
