1/28 Parametric Rim for WLToys K989 (uses Mini 4wd tires)
thingiverse
I was searching for some grippier tyres for my k989 and I had some Tamiya mini 4wd ones which are roughly similar in size to the stock k989 tyres. The provided stl are sized for the tyres I had. The design is parametric, you can change the number of spokes and the size using the fusion 360 file. Don't go over 5mm for the offset, or the rim will touch the wheel hub. The mounting hole is tight, file it slighty or heat (not too much or it will deform!) before mounting.
