I use them with no issue at all. BDop Valvinators will keep the rattling of the stem down.
+1 on the Valvinators from BDop Cycling. I have also used the 80 mm stems with no problem. You can also wrap the stem in electrical tape where it goes through the hole in the rim. If you don't want the Valvinators electrical tape works almost as good to cushion the valve hole also. Better than extenders for sure.
