2PCS Robot Car 95cm Crawler Tank Treads Tracks with Gear for Robot Tank DIY project for Teen Adult Gifts(Not included idler Wheels)

Q: How do you take off some of the tread?

Each link has a small metal rod connecting them together at the flexible joint you just take something thin like a straightened out paper clip and simply push the pin out through the hole.

Q: What is the width of the tracks?

The width of the tracks is approximately 1-9/16" or 40 mm. The holes in the tracks to accept the sprocket teeth are approximately 7/8" or 22 mm wide at their widest point. The spaces are about 3 mm x 5 mm. Hope that helps.
