Crazy Crawler LaserFoam "Heavy Duty 109x45" 1.9 Rock Beast XOR Foam Crawler Tire Inserts are precision cut open cell foam tire inserts designed for performance. LaserFoam inserts offer incredible lateral stability and sidewall support, yet still remain nice and soft on the contact patch. The material and cut shape ensure that the tire only rolls in the area of the tread that is in contact with the surface, creating great driving characteristics and an incredibly scale look. Plus, the soft open cell foam material allows the insert to fit even when internal wheel weight has been added.

These LaserFoams are RECON G6 Certified, and were developed specifically for Pit Bull Rock Beast XOR (PBTPB9014AK) tires. 

NOTE: The LaserFoam HD inserts should not be exposed to moisture for a long period of time.
