Guys when I was getting the 6x2 tires, I also noticed a complete set(tire, tube and hub) for $20. It needs a 8mm shaft with free length of at least 35mm. That makes it perfect for TB218. Mounting a pulley would be super easy using the 3 protruding bolts. I put it on a 8mm shaft and can confirm that there was no noticeable wobble. I ordered it on the 3rd and received it on 18th.
I bought a set of these a while back I’ll need to check but I think at the time they came with different hard pressed high resistant
bearings and the wrong diameter. I’ll have to recheck. Been trying to sell them to someone with more free time in Europe.
I think the rim will burst once you inflate the tire. The reason for my screws being so far away from the circle center is that they are supposed to eat the forces on the rim wall. In your design there is nothing helping the plastic to stay in place and the material is not up to hold several bars of pressure
Can’t see why it won’t work… But your pulley has not many teeth? I was aiming for something like 60T but the size of that would make it larger than the rim resulting in potential hitting the tyre when it flexes.
You can modify the design to have whatever width and how many ever teeth. I selected 50 because 42 would have caused the countersink for M6 bolt head to be very close to the teeth. You can easily go to 60 teeth, just change it in the solidworks equation.
Hi guys, I saw some great projects here. I’m strongly considering makeing 3d printed wheels for my future build. I’m worried tho. Using PETG for that purpose with its hydroscopic properties give me a doubts. Could you share your experience with me?
Got maybe 30-40mi on mine as well, no signs of wear. Unsure top speed as the trucks need new bushings to be safe. I don’t think they will be wearing out anytime soon. Printed in standard ABS. Some rings printed in PLA cause I ran out of ABS. Seems fine for now.
all pneumatics do - turn up the pressure to increase efficiency.
They can be bought as solid tires now - should be super heavy though and I am not sure if it actually makes a difference for rolling resistance.
I’ve got 250-300 miles on my PETG hubs, and they are holding up great, no signs of wear or cracking really… Although I did have to print the rims for the hubs out of nylon because the PETG holding the side walls was not enough and it started cracking.
