when will these fucking airless tires become a fucking reality

>le airless maymay again
When they can compete with pneumatic tyres, which is never. You can get yours today if you're keen. Don't say I didn't warn you.

>>1074647
Never
We can only hope for better materials on pneumatic tires

Imagine that shit filling up with mud.

What a joy.

As soon as materials science & manufacturing make suspension technology more weight and maintenance economic than pneumatic tires.
Basically we are talking about highly efficient suspension systems with solid rims that have to weigh less, ride smoother, and cost less than frames with pneumatic tires.

Doesn't seem likely, but it's not totally impossible.

they wont
there's a reason these things arent already on bikes and its because they're bad.

if you're scared of flats just get a tire with a kevlar belt and your problem is solved.

im gonna run down a quick reason of why these things are shit
>are either boneshatteringly uncomfortable and rigid, or so soft they're really inefficient, cant have the balance of comfort and efficency of regular tires
>no modulation, pneumatics allow you to raise or lower pressure depending on terrain, rider weight, riding style, and personal preference
>dont grip as well
> more costly and a bitch to replace after inevitable wear and tear
>can't deform to terrain, making it shit at cornering
>wont be as good/grippy as a good tire

the only thing they can get away with putting these peice of shit memes on are sub 500 bikes aimed for dumb moms

That all said, anyone tried inflating their tires with helium?

Enjoy pumping up those 25-622 tires every hour and that all for 0,2 µseconds of speed advantage

I know some people inflate car tires with nitrogen to improve mpg and also slow air loss (nitrogen molecules are bigger than others and leak less). I know air is 70% (?) Nitrogen anyway, but curious if anyone was into this marginal gain.

>>1074896
I just figured that there was going to be someone weenie enough to do it.

Nitrogen doesn't do shit to improve efficiency of the car. Also how shitty are your rims and tires if they can't keep air in them well enough that a check every few months isn't enough? The biggest advantage of using nitrogen is that it has smaller thermal expansion than air which means pressures are easier to control when you're setting up track tires where small differences in tire pressure can have drastic impact on handling.

Using nitrogen would actually be useful for rim brake equipped bikes with clinchers if you are descending a lot.

What I want is zero-atmosphere cycling. Imagine those olympic tracks but they pump all the air out and give everyone oxygen tanks.

Man everyone would be riding those speed record bikes

even schwalbe master race cant do it right.

Helium woud leak too easy probably. Air is fine and is free.

>>1074647
All those holes are going to create TONS of turbulences. Also they're going to pick up gravel, water, mud... So you better close these holes but then you're back again with a classic tire.

When there is a demand for them.
