Tired Flats was an expected location for World Of Cars. But it never got released. From the map, it looks like it's a location with overhead bridges. iWorld of Cars will bring back Tired Flats as an explored map that has to be unlocked by playing the games' seasonal races. However, the Route 66 road will not be like you see in the picture to your right. It will be connected by Redhood Valley instead of Wheel Well since the Route 66 road will go through Tailfin Pass, then Caddilac Range, then Crankshaft, then Redhood Valley, before it enters Tired Flats by a few overhead bridges with spectacular scenery. There will be two roads leading out of Tired Flats: One to Overheat Peak and one leading to Enginegrill Mountain.
