NZ can have some rough surfaces and we here at Mozzi want you to keep drifting & not worry about your tube popping.
If you are going through Crazy Cart wheels quickly, we recommend this replacement wheel. This is a solid rubber wheel that has no tube.
This is not official Razor product but we have tested this wheel & it does fit on the Crazy Cart XL & the Crazy Cart Black.
We do recommend using the Crazy Carts on smooth surfaces to the maximum life out of your wheels.
