Seems this could work.
Infraction 3s TPU tires.
Test prints:
Tires has to be pressed onto the rim. Pretty easy. Find one point and insert Srewdriver. Then a few centimers further another srewdriver. Them press down inbetween and work around. Seems like it does not even need glue. Will add a few drops anyway.
Tire diameter same as stock. 85mm
Wall line count: 8 with 0,4mm nozzle.
Top Layers: 6
Bottom Layers: 6
Infill: 70% - pretty hard tire. Probably less better.
Material: TPU
Print Speed: 150mm/s
Time: Just under 4 hours on Anycubic Kobra 2
Support needed for tread pattern
Brim: 30 lines
Tire weight with rim: 105 grams vs. stock (I think) 86 grams
Internal pattern inside the groove of the tread:
Internal pattern outside the print tread. So thats 0,4mm x 8 walls = 3,2mm can be hooned down until the tire reaches the end of the tread. Could be that the infill acts as pattern now. Not too sure about that.
(Might be too wobbly. That would add at least a 2mm of added hooning. Thats about 5mm that can be hooned down and a total of 1cm in diameter. At that time the 85mm diameter is down to 75mm. It might make sense to have infill of 30% so infill becomes the new "tread pattern".) But 6mm hooning of the diameter will be possible.
Still busy printing the other tires. So I have not tried them.
I'll put the files on thingiverse when this works out like I want it to. Hopefully someone with some more design skills could work a proper tread on to the tire.
