Production models will have walls to hide that mesh. Will look more clean and have less aerodynamic effects.
>>14066963
You can clean it
>>14066963

old as fuck, still hasn't taken yet. no one really cares
>>14066950
The next step in stance?
>>14066963
there are more pressing reasons to have the sides covered than that
>driving along on freeway
>rock somehow bounces into the spokes

lets see it do above 20kmh

A bunch of different military forces are either field testing them or exploring their use for vehicles as grenade proof.
I would imagine they don't do well at highway speeds, but could have a ton of strengths elsewhere.

i think they will fill with mud and destroy dampeners on the trip home.
>>14066950
Looks like they would bend over the rim around corners, maybe good for a city cruiser car?
>>14067052
They won't.
When they will enter mass production they will have covered sides.
Those with exposed mesh are only for demonstration.
>>14067095
Will mud really not cause any problems here?
>>14067115
If you cover the holes, than no problems with mud.
>>14067115
It totally would. Change the weight balance of the wheel and if you're going to get more vibration at speed, and you're going to get more vibration beating apart the steering linkage, and everything else attached to the wheel. If you were sticking to relatively low speeds however that effect probably wouldn't be pronounced enough for there to be any noticeable effect.
>>14066950
Given the fact you can't regulate air pressure (and therefore footprint), I can't see this being useful for any offroad application other than driving over staged obstacles.
>>14067123
Honest question: How important is regulating air pressure for off-road?
>>14067122
That's why it would be covered, not exposed like in this DEMONSTRATION examples.
twankay werejg
>>14067126
Honest answer, Extremely. More important than the thousands of dollars worth of crap you can bolt to your vehicle.
>>14067126
Every dedicated heavy duty off road vehicle will use some sort of central tire inflation system to allow the driver to adjust air pressure on the fly. They have these systems because they're that incredibly important. All the torx and power in the world won't help you if you lack traction, you'll just dig a hole. A wider foot print of your tire increases traction, its vehicle weight over the surface area of your tire touching the ground. Not much of a tire directly touches the ground under normal circumstances, so increasing this area has a massive effect on the weight to surface area ratio.
>>14067008
Yep.
From what I've gathered they overheat when you drive fast for longer periods.
>>14066994
Oh God I can't imagine having airless tires with the space between them filled by their toys or stones by my kids!
How about deformation? can parking a car for a hot ass week without it moving fuck up the tyres from basically being baked?
>>14067219
Thats probably a real issue. Conventional tires are containers for a gas, and that compressed gas is like a spring. We can replace that gas when it eventually leaks out. An airless tire uses a physical spine structure to handle that same energy that the compressed gas in a conventional tire is handling. The airless tire however has far more localized energy storage, and no storage container is perfect. Every single spring will lose capacity to hold energy over time.
tl;dr parking a vehicle for a long time on one of these wheels could likely damage it.
The material used would have to be designed with this in mind. Springs used in rifle magazines are designed knowing that they may be fully compressed for extended periods of time, so they make them slightly longer and stronger than is actually needed. Airless wheels would need the same treatment.
So they're good for off-roading and mars rovers but how do they feel on regular roads at highway speed?
>>14067219
>>14067242
You'll just have to change the airless tires once in a while, so what.
>>14067101
I'd like to hold her airless tires. If you know what i mean.
>>14067249
Try them and tell us
>>14067259
so whats the point of using airless tyres when normal tyres have longer service life. the supposed benefit of airless tyres is less shit to go wrong
>>14067277
>normal tyres have longer service life
wait what? why?
>>14067284
the ability to fill it with air when needed and good tyre life
>>14067293
I'm still not getting it, why would being filled with air extend the life of the "tyre"[sic]? I would think regular tires would have shorter lifespans since they become useless after they get even one tiny hole.
>>14067319
The rubber, bands, and walls of a conventional tire are just holding in a gas which is doing all of the hard work. That gas is completely expendable, we can replace it any time we want.
An airless tire uses a fixed solid thing to support the weight of the vehicle, and we can't replace them when they wear. The entire wheel would have to be replaced.
>>14066950
How do you change it?
>>14067319
tyre is the british english you mongoloid
but i guess tyres are useless after a puncture
>>14067339
Like a regular tyre
>>14067330
>The entire wheel would have to be replaced.
Maybe it will be really cheap.
>>14067319
>colonial tries to be smart and fails miserably
>>14067351
Probably would be if the material was cheap enough.
>>14067330
I guess that makes sense. It still seems like the center mesh could take a lot of wear and tear before it no longer functions.
>>14067340
Yeah, I know, m8. It's banter.
>>14067351
>A tyre with far more material would be cheaper than a normal tyre
>>14067343
How do you change the rubber part then?
>>14067156
I learned something today and i haven't even gotten out of bed
Like a regular tyre
>>14067105
why is her body so square? she has cubes for tits
>>14067262
with a face like that, she will probably let you
>>14067396
She isn't human
>>14067008
They get a bit of use in LGP plant where you can't use foam filled or solid tyres and maintain the required ground pressure and a puncture could be catastrophic for example in MEWPs where you may be working at height. The problem is they are massively expensive.
>>14067364
You only replace the treaded section unless you do something massively stupid to damage the core.
>>14067008

Her dress is fucking ugly, it looks like a bad Star Trek Halloween costume.
Fucking retards probably thought it would match the "Space Age" tires.
>>14067478
She's taller than most of the male owners that will buy such a car.
>>14067496
>>14067510
Would you fugg her or not?
When we get wheels and tyres like these, call me.
>>14067510
she isn't tall, you mong. she's wearing 6" heels
>>14067514
I have zero standards and even I'd still refuse.
>>14067517
>5'4" female
>6" heels
>about 5'10" in total
still taller than most men who will buy such a car
>>14067516
But we need a car without wheels, no suspension
>>14067541
will it fit on 18" rims on my honda? don`t think so. useless.
>>14067573
>rims
>>14066950
Wow, it's like a normal tire, only more expensive and you can't adjust the pressure.
>>14067641
And you can't get a flat tire.
>>14067647
I've never had a flat tire in my entire life.
Try living in a first world country with good roads.
>>14067647
RIP off
What is the impact on power and fuel economy?
Flexing rubber generates heat. Heat is energy, and energy has to come from somewhere - it robs your vehicle of power and fuel economy.
A truck fitted with "Super Singles" gets over 6% better fuel economy than one with dual tires, because there's half as many sidewalls, which is half as much rubber flexing, generating heat, and stealing energy.

Open a book some time.

Please forgive the use of non-SI units not accepted for use with the SI. The author is no doubt paying for these sins in the afterlife as we speak.
>>14067051
What are these?
>>14067262
Not really, what?
>>14067649
Tfw I have the worst luck with flat tires on any road
>>14067698
For bicycles
>>14067372
No you didn't, trust me.
>>14067008
Yeah was gonna say. Old as hell and dont see this taking off anytime soon. Only time I see tires similar like this is heavy lifting equipment at my job. The Clark forklift I drive for example. All rubber compound wheels
I wonder how it feels to have a "blowout" with one of these?
>>14067826
>blowout
Won't happen
>>14067845
There will always be tire failures anon. Always.
fucking retarded
>>14067519
>implying you would
>>14067671
Wow, you're dull.
Guess what decreasing tire pressure does? It increases the surface area contact to weight ratio for your vehicle.
Trying to be snarky when you're this laughably stupid is just hilarious. I doubt you even graduated high school.
>>14066950
To noisy, but will put them on the Electric Tesla killer I'm building.

he's talking about the pressure exerted by the tyres on the ground. not the pressure of air in the tyre
