Hey, Here’s Another Airless Tire… Will This One Catch On?

Every few years, the bike industry revisits the conversation of airless tires. Some are 3D printed, others are formed from a solid chunk of polymer. And some, well, are so high tech, they can go to the moon.

Yet, aside from a booth at the occasional trade show, we rarely see airless tires out in the wild (except on a few hybrid bikes like the Specialized Alibi). Could Aipex’s airless offering be the one that finally gains more widespread acceptance?

Aipex Aireless Tires

Currently, Aipex isn’t sharing much information about its airless tires. They are unreleased, and Aipex has an email sign-up to join a waitlist. From the pictures and video we’ve seen, which are a prototype, the tires have hexagonal cutouts in a 1-2-1 pattern. The tires also appear to have a road and dirt option.

As for how they are constructed or what the material is, Aipex hasn’t yet said. However, their airless motorcycle tires are manufactured by ND Rubber in Thailand. Aipex says this is the “manufacturing giant producing over 3.5 million tires annually for trusted brands like Yamaha and Suzuki.”

Here is what Aipex tells us. The Aipex Airless Tires have tread that will last up to 6,000 miles. Once the tread is worn down, it can be replaced. They are obviously puncture-free and have a weight capacity of 200lbs. 

So, can we expect these to be the airless tires that catch on? Will we see them on any bikes soon? Well, not any bikes in my garage. At launch, these Aipex will only offer a 26 x 2.1 airless tire in the “road or off-road” tread.

That said, Aipex also claims to have more sizes in the future. Hopefully, we’ll also see a sneak peek into how to install the tires and replace tire tread. 

Who knows, maybe we’ll get a set in for testing. But we’ll need to get a bike with 26-inch wheels first. See more at aipextires.com.

I don’t want these tires, but a lot of people who own a bike would use it more often if they did. Freeing the owner from routine maintenance like tires, lube, and basic adjustments would save as much time as a motor, plus a lot more money.

It is hard to imagine that dealers love the idea too much, which should also put a little perspective on who is really behind internally routed cables, etc. Mechanics complain, but that is the butter on their bread.

That’s the thing about airless tires though – they seem like a good idea on the surface, but in the real world they leave a lot to be desired. I tried them on the Specialized Alibi mentioned above, and my dad liked that he didn’t have to inflate them, but found that they rode too stiffly so we ended up replacing them with normal tires and tubes.

Unlike a pneumatic tire, there is no way to adjust the ride quality for various body weights, so a tire that is stiff enough to work with a 200lb rider will not offer a comfortable ride for someone much lighter.

Really for these to take off, they need to be offered in different stiffnesses for different rider weights.

Previous airless tires also tended to lack grip in wet, sandy situations, etc., but maybe these will be better with a replaceable tread?

I don’t really care whether or not you review these things, but… you don’t have access to a single old mountain bike? Millions of them are gathering dust in garages as we live and breathe.

I’m surprised that there is even companies working on bike tires such as these. Most current mtb, gravel and road tires are pretty damn good and reliable, especially if you have a tubeless system dialed in.
I’ve seen similar prototype tires for cars and think this is a lot better application than for bicycles

This system is for the opposite end of the spectrum from tubeless. If you only ride a bike once every 3 months and can’t be bothered to pump, this is for you. With tubeless you’d at best need new sealant basically every time you ride, at worst you need to completely redo it because you lost air and the sealant all dried.

I hope bicyclerollingresistance reviews one of these wonders. Infinite puncture protection and laughable rolling resistance…

The market for these must be public e-bikes (Lime etc), where the extra rolling resistance is never felt because of the motor. Traction in the wet is still a concern though.

Wouldn’t the increased resistance be felt in reduced range? It seems like really thick pneumatic tires are puncture resistant enough already. And public ebikes have a dedicated team of maintainers so it shouldn’t be that hard to replace tubes occasionally.

But I wonder if you could combine an airless tire with a pneumatic (tubeless?) setup, to get a tire that works well normally and runs ok even when flat. Then you can still get to your destination and fix the tire later.

Another vote for ‘these don’t appeal to me’. They look way non-supple and probably heavy. And ‘launching’ a product with so little info is kinda questionable.

That said, given how many bikes I see for sale where the owner says ‘works, just need air in tires’ suggests that the simple act of putting air in tires is a big barrier to riding.

If they didn’t have such a low weight limit (200lbs – 25lbs for the bike 175lbs for rider and cargo?), I’d think them a candidate for my around town commuter. but…
