Rimstrips and extra rim holes

I recently purchased some Somax wheels second hand and after receiving them i found that they had some extra holes near the sidewall that I fear will be difficult to cover with a rimstrip (see below), but will result in flats if i don't. The overall width of the gap between the sidewalls is about 18 mm, so i may be able to get by with a 22 mm strip, but am still a little worried about that. These holes appear to have been added during manufacturing since they are anodized on the inside walls and there are a two sets of four of them on each rim, one next to the two nipple holes on each side of the valve stem hole and one set next to the two nipple holes where the rim was welded together.

Has anyone here seen this before and/or have any advice for me.



Thanks for looking

Narrow Velox rim tape .. the smaller holes will be covered by the tire bead edges..\

Because, where they are is the Tire Bead seat ..

& trying to use a wide tape to cover everything, will make tires harder to mount

and Doubtless, the strip will be pushed off that ledge unevenly as you put the tires on.

Agree on the rim strip suggestion and the lack of these side/small holes causing issues. Many (maybe many millions over the years) of rims have these tiny holes and they haven't caused flats in any number to known about. Andy.

interesting... i've never seen that many holes that big in a rim like that. i probably wouldn't try to cover them, and see if they cause a problem. if so, i'm not sure what i would do. probably get rid of the rim.

I would cover them --maybe with a thin piece of mylar-like tape. They look almost big enough to suck down thin tubes and ultimately compromise them.
Actually I wouldn't use that rim.

If one must do something about the small holes then plug them with a caulk of sorts. No extra build up on the bead seat for the tire to have to deal with. Andy.

Auto body filler might be a good choice. Fill the holes all the way to the bottom so the pressure from the tube doesn't punch the plug out. If you smooth it out with the plastic applicators sold for that purpose you likely won't have to sand the plugs down.

I've seen small holes in steel rims. What is that on? BMX?

How many of those holes are there? 4? A bunch? And they're pretty big.

I'd be tempted to caulk them, or smooth out the corners first, then caulk.

If you want something tough.. JB Weld?

Thanks for all the feedback. I agree that maybe the tire bead will cover most of the holes, but I may try to put some small pieces of electrical tape over the holes and/or sand the edges with high grit.

CliffordK, there are a total of eight holes per rim, two sets of four.
