Are these 29" Alexrims RHD double wall trims tubeless?
 

Are these 29 inch double wall Alexrims RHD rims tubeless? I can't find a part number on them. The Alexrims website is not helpful. Thank you in advance.

Are these Alexrims RHD double wall tubeless?

Thanks

You can tell by looking at the rim bed.

Only hole in a tubeless rim is for the valve stem , Otherwise you are converting something else and trying to make it air tight..

I saw those holes in the eyelets by the spokes. I guess I didn't add 1 +1. On the other hand, I'm new to this stuff, I thought maybe there was a rubber strip on the inner rim.
Anyway I bought new tubed tires today and tubes to be safe.

thanks!

This is wrong in the modern sense of how the term is used. The vast, significant majority of rims sold and intended for use with tubeless tires rely on rim tape to form a seal with the spoke holes, which works fine, even at high road pressures (though it may take two laps of tape vs 1 for offroad pressures). What makes a rim designed for tubeless is the shape and tolerance of the bead shelf and the presence of a center channel for mounting. This is annoyingly somewhat inconsistently standardized--most everything on the MTB market works pretty well, on the road side things are pretty good these days but some combinations are really hard to fit, and some tires specify they must be mounted on hooked rims (some road tubeless rims are hookless), etc.

Bead shelves aren't unique to tubeless rims. So yeah, not a good indicator of whether a rim is tubeless ready. They are, however, kind of handy on non tubeless rims when used with something like Joe's Rim Strips, which are made of thick rubber that fills the gap between the tire bead and bead seat

Tubeless?
I mounted tubed Serfas drifter tires on the rims today.
While I had them off I took this picture. I was surprised how light the rims are
When winter and the rainy season hits, I can use tubeless tires, right?

Best thing is to try them, see if they seat snugly.

tubeless tires... with an inner tube..

I thought using tubeless tires with tubes caused over heating
