Type of TPU for wheel loader tires

[modest night]

Hi, Im currently printing my own design of the Volvo L350H Wheel loader. Because of the size of the tires im left with no choice but to 3d print them so my question being. What type of TPU would fit well for that? Thick tires which are meant to be quite hard but also rubbery so it actually has some traction for driving around and getting up on trailers.

TPU95-HF should be a good candidate

TPU95-HF is awesome for printing large models, it's quite hard, but also can be kind of slippery

TPU90 is a little bit more grippy, a little bit softer, but not really soft when done multiple walls but a little harder to print.

I will say that if you don't have experience with TPU go for TPU95-HF

TPU the more walls the less softness. Surface softness on 95 is not that good. 60-70 closer to car tire.

60 is getting into to silicone shore hardness, a true 70-80 is what Google thinks a car tire is. That said it is really really tough to accurately know how a tire is going to be printed to say ‘this is what to use’. I bet if you modeled the tire so the treads were hollow and one wall (.8) and connected to an inner core via the valleys of the treads 90 shore hardness would do the trick.

Yup sounds good. Sure I’ve Fulda Extremos on a summer car. Rock hard they would disintegrate in snow. For drags you need something going from flat to tall. Wrinkle wall.
