If you’re still trying to piece together the LEGO DC Comics Super Heroes Bat-Pod (5004590), you’ll find that the hardest part to find is probably the tires because they are only available in The Tumbler (76023). Many have been trying to purchase them off Brick & Pieces but they’ve been out of stock for a while. The good news is that they are now available to purchase again at a decent price of $11.02 per tire which is a bargain compared to $30+ sellers are asking for on BrickLink. I highly suggest that you purchase them now before they go out of stock again. The only downside from ordering from Bricks & Pieces is that you won’t earn any LEGO VIP points or qualify for any promotions that are going on.
Update: And it’s sold out again. I won’t keep updating on its availability. You’ll have to keep checking when it comes back in stock.
