Metal valve stems/ rim liner

I am about ready to mount my tire on my rims. I installed metal valve stems, correctly I hope. Now I am having second thoughts about using the rubber rim liners I bought. It seems like there might be a problem with the ends of the bridge washers cutting into the rubber rim liners and maybe cutting the liners in two. The bridge washers aren't sharp one the ends, but it seems like there would be substantial pressure on the rim liners, possibly cutting into them. Is using rubber rim liners (to protect the tubes from the welded spokes) the correct thing to use when using metal valve stems? Thanks for any help with this.

Yes, you still need to use the rim liners. The bridge washers will not cut into the rim liners. They will be snugged down, but they will not be tight enough to cut into the rim liners. The way they did it when new is still the right way to do it.
 
Which "rim-liner" are you refering to?

I know of two types.

There is the one that looks like a rubber band and is about an inch wide; then there is the one that is much larger in size and shape.

Not sure which was actually used.

Anyone?

The last set of stems I installed I used a set of 16" rim liners, only because I had them and didn't want to buy new 21" liners, they worked real good and actually did a better job of covering the inside of the rim.
You should always use rim liners when installing metal valve stems, the old way is still correct.

Rim liners, being referenced as rubber bands, are the narrow item that fits down in the recess of the rim.

The wider item is a rim flap. These were used on truck rims. Guess a rim flap could be used on a passenger car rim but it is not necessary. Plus, a rim flap may have a tendecy to curl along its edges once in the tire. That could cause chaffing of the tube. Rim flaps are really too wide for either 21" or 19" passenger car rims.

Original rim liners were cardboard about an inch wide and probably about 2 or 3 times as thick as a Corn Flakes box.
 
The wide rim flaps are for flat base demountable rims like those on a Model T, not drop center rims. :)
