Most dump carts have tires ranging from about 13” to about 16”, making them rather useful on rough terrain. That’s because the height of the tires forces the cart to rest higher above the ground while in motion. Since the clearance is much higher than say a 6” tire, your dump cart will be able to avoid obstacles, bumps, and brush during your travels successfully. What’s also important to note is the center of gravity of your dump cart. The higher the center of gravity is, similar to a large truck or SUV, the more likely the dump cart will tip or sway. One large bump or hill might send your supplies flying if your bed sits too high above the ground.
