Descriptions:
1.9'' crawler tire foam, crafted from high-quality silicone rubber, providing more superb sidewall support than regular foam to keep the shape of tires. They are heavier than traditional sponges, it increases the weight of the chassis of the crawler car, making the crawler car more stable during climbing, and effectively increasing the weight to avoid overturning during climbing.
