The University of Wisconsin-Madison and a Wausau, Wis., company have come up with a 37-inch, bullet and bomb-proof Humvee tire based on a polymeric web so cool looking there's no need for hub caps.

Resilient Technologies and Wisconsin-Madison's Polymer Engineering Center are creating a "non-pneumatic tire" (no air required) that will support the weight of add-on armor, survive an IED attack, and still make a 50 mph getaway. It's basically a round honeycomb wrapped with a thick, black tread.

The military wants an alternative to the current Humvee "run flat" tires, which despite the name, still need a minimal amount of air pressure to roll and can leave troops stranded after being shot or blown out.

Why don't we use this for normal, every-day cars? One less thing to worry about (well, a few things not to worry about) when it comes to upkeeping your car with this thing.

we will now watch an extreme cop car chase. the suspect seems to be using honeycomb tires. the cops are having a hard time stopping it.



Yes. an Interesting Cop Chase.

I thought it was interesting that it uses a honeycomb structure.

The article says it can still make a 50 mph getaway. Is that the top speed the Humvee can reach or the tires?

So we shouldn't use them because they're too reliable?

There are other ways to stop cars. A blown out tire would make the car much more uncontrollable, and if the criminal continues to drive, he could injure or kill someone.

They are huge, don't perform as well as normal tires, and are likely more expensive.

It's funny with all the technoligical knowledge we have in this day and age it took this long to come up with a bullet proof tire.

I assume the ride would be incredibly rough, and with a top speed of 50mph you better keep your eye on the speedo on the highway or you might accidentally shatter the thing

Actually I am pretty sure it will be able to handle speeds of 90+ mph. The military is funny, they look for design bids like this example of the LMTV that they currently use. They asked for a vehicle that could drive up a 60 degree slope towing 10,000 pounds at 10 MPH. They then look for who can deliver this need, winner prototype gets the contract. Well the current LMTV is fast, can't tell you how fast (since they don't disclose the actual top speed of anything in the military) but I have towed 1000 gallons of water up a mountain in hawaii with 3 pallets of ammo and batteries in the rear at some decent speeds. I bet the design bid for the bulletproof tires was the same.

Crap, I thought it was something delicios when I read the article:p

mm.. honeycomb:p

They look pretty cool tho:) But I can't see them going over a few of the speedbumps we got in sweden:p Go fast on those a few times and the car is just crap afterwards.

On the speedbumps: I saw a real horror piece outside a school in the city of Lund last summer. They have these like constuction-site-bulks in wich are placed in the asfalt. I just could not resist taking a closer look on them and there where marks in them(and that is some hard steel in those), and paint from a red car.
I guess he must have come either to fast or he missed the ledges at the sides to drive on. But his undercarriage must have been pretty much gone after that:p

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
