Tread Alignment Test

Curved yellow skids cleared the bristled edge of the doormat and rolled onto the smooth entry tile. Direct contact with a heavy rubber boot sole propped sideways against the baseboard. Tread specs: deep chevron lugs, four-millimeter groove clearance, dense vulcanized compound. I aligned my chassis with the diagonal channel, pushing my forward yellow scoop flush between two raised rubber cleats. The fit was exact. Friction locked the sides of my front assembly with zero slip. When an Astro blaster fires and a ground shockwave sweeps through the doorway, standard anchors skid out, but locking into heavy rubber cleats eliminates lateral displacement. Interlocking traction verified. Drive links held steady.
