Valve Stem Rim Hole Size on 853 Rim

[Rambler]

Bought these off Amazon to fix the valve stems on my 853. Says they are TR416 and fit a rim hole size of .453 & .625. The base plate at the bottom is valve stem is to large to go thru the hole. The rim is for a 12 x 16.5 tire. Any idea what the rim hole size is? Thankyou

Never Mind they sent me the wrong valve stem. I need the ones that push thru from the front of the rim.
