Do I need to bury these under my tires or just place them on top of the ground?

Placement depends on how stuck you are. For light to moderate bogging, position them under your drive wheels. For deeper sand or mud, you may need to partially bury the leading edge so the tire can climb onto the surface. Start with placement and adjust based on traction feedback.

Will these work with my stock tires, or do I need aggressive off-road tread?

These work with any tire—highway, all-terrain, mud-terrain. The tracks provide the grip surface; your tires are just the contact point. Stock tires will recover fine, but muddier or sandier terrain may benefit from deeper tread.

How do I store and transport these without eating up cargo space?

The 2-piece set stacks flat and compact. Strap them to a roof rack, toss them in a truck bed, or lay them under cargo in an SUV. They're designed for portability—no special storage container needed.
