Granite Grom tire upgrade

Hi all! My kiddo loves the Granite Grom! Did some parking lot and minor off-road bashing and it performed great. Unfortunately when we tried using it on my artificial turf backyard, it failed miserably! The tires couldn't get any traction on the nap of the turf.

Any suggestion for upgraded tires that would allow for some backyard bashing, while still being performant on pavement, dirt, and real grass?
