WLToys K989 Monster truck wheel

thingiverse

Increase clearance for your K989 with 50mm wheels by adding 2mm to its dimensions. Also, expand track width to 102mm to ensure smooth movement. Lego tires are compatible with these rims, specifically the 43.2x22 size. These rims will not work with the default body shell as they rub against it when turning. Rims and tires have different materials - PLA for the rims and filaflex for the tires. To assemble these wheels, use the same bolts as the original but be prepared to use a long tool to tighten them securely.
