I made a replacement tire for an old audi quattro bobby car out of TPU.
It's not a 100% copy designwise, so if you like a clean look you would have to replace all 4 tires.
I'm not sure if it also fits the original “bobby car neo” wheels - but i'm pretty sure it won't fit the classic bobby car wheels. Maybe you want to check dimensions first if you want to give it a try.
It prints just fine without support for the tire tread - so only for the inner part you will need support as shown in the sliced model picture.
Print settings:
material: TPU SemiSoft
Layer height: 0.2mm
perimeter: 4
infill: 25%
