I found this on the TecTro site. https://www.tektro.com/upload/Product/F_20210705110681iXimE7.PDF

Says both the E10.11 and P20.11 works.  Since RAD specs the E10.11 as a spare part so I went with the performance version P20.11. They can't be noisier than what came stock. They also degraded somehow (rain?). I will report back in a few months if someone reminds me.

Has anyone tried a S&M  22 x 2.4 tire on a radwagon wheel?  Obviously you would also need a matching tube.  I've had some issues with this bikes tires and I think its bad manufacturing from Vee tire co.  I have seen some posts about building a 24" wheelset but I don't want to do that unless I need to.  I cant find any other options for a 22 inch tire.  Any help would be HUGE!!!

When you say bad manufacturing, I am wondering if you have the same failure mode as me. I have never seen a tire fail like this before. Of course RAD says "ware and tear" which after 6mo of riding is unacceptable not matter how I ride it (I'm not jumping!).
