Our durable tire bases are made from extra heavy duty angle iron, steel tubing, and heavy plate steel reinforcements. All welds are "full line" welds, as opposed to inferior "spot" welded products. Finished with a thick silver powder-coating to ensure durability in the harshest weather conditions. This ground spike is designed to display Swooper Feather Flags and Wind-Free (Windless) feather flags under a car tire (usually at a car dealership) and is designed to be used with our Deluxe 4-Piece Flagpole Sets.
