My son has a Razor Crazy Cart XL. The tube tires go flat quickly, will this work on his cart? He rides primarily on street pavement.
This tire would be a great option for your son's Crazy Cart XL! Please note, sometimes foam-filled tires can be tricky to install, so we carry a tire installation tool to assist with that. You can find that tool as item J94-1341, here:

On that page, you will also find a video showing how to perform the installation.
