Tubeless conversion RIM
 

Hi folks I am new here I was looking to replace my spokes rims with aluminum and found this https://www.engtb.com/item/taobao/618262219884.html
Anyone tried? are they straight fit?

I believe those are the OEM cast wheels for China and Asia market RX3s. The problem is that they come with a 15" rear; that size tire is damn near impossible to source here in the US in a dual sport tread. There are several street and cruiser tire models available in that size wheel, as well as the Bridgestone Battlax Adventure A41 that is used on the front of the Yamaha Niken; but nothing for off road riding, and that kind of defeats the purpose of riding an ADV bike - to be able to venture off pavement.

Useless tyre sizes
I do have a new spoke wheel and made tubeless with shinko tire I could send to USA around $250 total

I'm planning to use my bike 95% of the times road use, and I like the idea of upgrading the front brake to a floating disk with 4 piston caliper (the actual one really sucks).
What sort of tire size can I fit on them rims?

Front and back?
