I'm familiar with similar Shinko rear tire on my 1978 Honda Trail90 scrambler:


The OEM tires that came with the cargo ebike are just too noisy for me.
After changing the front end, it was much better, I just kept the rear tire as is until it wears out, but with +2k miles on it this year, it is still holding up.
Rear tire noise is not as bad as having a front noisy tire.
Really lucked out with this cargo ebike purchase, the order was placed just before the pandemic got bad and the ebike arrived when the world was still quarantined.
I got to ride the cargo ebike on more empty streets than the usual NYC metro.
I'm happy with the Alibaba purchase experience overall, it is certainly not for everyone.
With the supply chain and oversea shipping backlog issues, buying ebikes directly from Chinese manufacturers may be something to avoid for now.
