I touched base with Tannus to see if they plan on offering a new tire insert size for the Radwagon 4. I was pleased to hear that they are working with Rad on this right now. I was also pleased to hear that they have a size that will work today. It requires a different size tube but you can find that size on Amazon. The reply to my email is below. Here is a link to that product he is talking about. Sounds like Rad might offer this direct in a few months

BTW I did inquire that he was indeed talking about the new 22" x 3" tires and not the previous 24" size. He did confirm that he is talking about the new 22" tires

We are actually working with Rad Power Bikes on this size right now. We have a 24x1.95-2.5 that fits perfectly in this size. You will need to buy a new tube 22x1.75-2.3 should work fine for your needs (we don't sell this size on our site but you can get it on Amazon). Please let me know if you have any other questions.
All the best!

Well that's pretty interesting since that can solve the issue of having the buy the tubes from Rad if you are using the Tannus liners. I have a few sets of Tannus Armor en route to check out and will let everyone know what I think.
Any updates on how this insert is going? I'm also going from a mountain bike to the RW4 and feel pretty leery about taking it on the gravel paths and easy trails that would make my family riding life more fun!

I'm very intrigued by this information. I'll wait until they are an OEM part...
I posted this somewhere else on the forum but thought I'd share it here just in case people were reading this thread still.
The Tannus kit for the RW4 comes as a 24" kit with instructions to cut it. My local bike shop said with a little extra effort they were able to use it as is and it fit just fine, no cutting required.

How has it been so far? Any changes to the ride comfort with this installed, for better or worse?
Hi all. First flat yesterday at mile 70 or so. Tubes are backordered as usual. Looking at the Tannus Armour bundle. Has anyone sourced this from somewhere other than directly from Rad? Any alternatives? Pricing seems high, but cannot find anything else on my own with an hour of searching this morning. Thanks!

I find it questionable of Rad to sell a bike knowing well enough that the most common replacement part is currently not available. Having that more custom kind of tyre size was one of the main points of criticism from the get-go for the wagon...
Just ordered 24" Tannus inserts directly from the Tannus website and was able to find 22 x 2.1" tubes online as well. Combined total is $100 with shipping rather than $143 through Rad Power. Should all arrive in a couple days.

Please share your experience with the install and how the ride changes afterwards.
Update...the 24" Tannus Armour and 22" tubes shipped quickly and I was able to install on the rear wheel late last week. All is well after a few rides, even with a full sized passenger on the back. I don't notice a difference in ride quality, unless maybe slightly more cushion. The rear tire is inflated to about 40PSI. I'll eventually do the front tire, as well, but I had just filled that full-sized tube with slime so may I'll leave it as-is until I have an issue and then install the armour and smaller tube. Here's what I purchased:
https://tannusamerica.com/products/armour-tube-bundle?variant=31991227285615 (24" with no tubes)
https://www.danscomp.com/s-m-22-inner-tube-schrader-2.1-2.4-05-tube-22/p-5uqvs2wqbcaxqage?v=1225413
Total cost delivered is about $100 vs. $165 from Rad.
Installation wasn't too bad, just make sure the wheel is well supported and don't damage the disk rotor.
Cheers!

Tannus also made a video on their end:

Sam, thanks for sharing your experience!
Installed the Tannus kit on my RW4 yesterday as well. Will give it a more thorough test ride today to see how it goes. No major differences in ride quality on my short ride yesterday.

I wonder why Rad decided to go with a 22 inch size. Why not 20 inch which is much more common and it would help Rad too to have to stock fewer parts - like at least fewer tires and tubes.
Had a flat in the middle of the new tire after just two days riding with Tannus. I couldn?t locate a puncture hole in the tire or the Tannus so I suspect the tube was just low quality to begin with.
Any recommendation for a good 22 x 1.75 tube? Luckily my flat was in the front tire as changing the rear with a mounted Conestoga is a bit tricky.

I'm going to try the Dan's Comp brand (or likely, what they just sell as the house brand) in the 2.1-2.4. https://www.danscomp.com
WTP also has a smaller 1.75 tube:
https://www.danscomp.com/we-the-people-22-bmx-inner-tube-schrader-1.75-2.125-30001010218/p1192016?v=729869
I think the S&M brand also has a 1.75 tube (Dan's seems to only have 2.1-2.4), and they're at least more expensive that most tubes, so I'd hope they're actually better.
There's also these $34 (!) tubes form Tubolite https://www.danscomp.com/tubolito-tubo-22-24-bmx-inner-tube-schrader-1.5-2.5-33000098/p1421775?v=1329365
UPDATE. I knew I read it somewhere, so I got out my Tannus installation guide and on page 3 under Tips For Installing Tannus Armour it states (It is common for the Amour to compress over time. It still is providing shock absorption and puncture resistance but will perform better when properly maintained. To minimize compression deflate the tires while not use. This allows the Armour compound to rebound to provide ideal performance.) So does that mean when your not riding your bike, your suppose to let the air out of the tires? I'm sorry but that's not happening. I don't know how everyone else feels, but if I would have known that earlier, I would not have purchased the Armours.

I agree
