This design try to emulate typical Buggy Front / Rear wheels.
You can see the front and rear size of rims is different, but also the tires are in size and pattern.
They weight the same than the sourced ones I have, but you can't expect the same behavour, specially, "grip" of TPU in some kind of surfaces won't be the best.
If you find a really low shore filament at a reasonable price please let us know!!!
In the other hand, the geometry of the patterns in tires will make its part in terms of grip for some other kind of surfaces.
I created 2 versions of the Front Rim, one to align "correctly" the wheels like a normal buggy and a 4mm offset version of the Front Rim to have same total width in both axles.
Remember to print your rims with a good inter-layer adhesion (if you can go up 5 or 10ºC in your extruder without damaging, it will probably do the work) so you don't have problems when you have to put the tires on.
They use 12mm HEX and the depth of the place for the HEX is 4mm. The 4.2mm hole in the center of the wheel must be cleaned up before use and it should be 2.9mm deep.
You can find the main measures of each part in their filenames.
Both Rims and tires has been designed to avoid using supports. Get your printed good tunned to have the best results possible in the risky overhangs ;) Sink your tires a very little in your bed to have a good and secure print start
