Suggestions... these aren't necessarily things I'd use myself IRL, but I'd use most of them in a video game: https://tirecovers.com/exclusive-tire-covers/knot-all-who-wander-spare-tire-cover.html https://tirecovers.com/exclusive-tire-covers/smiley-face-spare-tire-cover.html https://tirecovers.com/exclusive-tire-covers/doughnut-tire-covers.html https://tirecovers.com/exclusive-tire-covers/kiwi-fruit-slice-tire-cover.html I also think that you could improve your compass wheelcover skin. It currently includes only the 4 cardinal directions, but IMO you should add smaller marks for the 4 primary intercardinal directions. You could also add a pointer or some other embellishment if you like, see the two links below: http://www.worldatlas.com/aatlas/infopage/comprose.htm https://tirecovers.com/exclusive-tire-covers/compass-due-north-tire-cover.html
I don't mean to bea grammar Nazi, but did you mean Hoppin' Around for the Hoppi'n Around cover? Also I think Hoppin' 'round rolls off of the tongue better Just an idea.
