H front tire question

Nearing the end of my restoration and was mounting a new 550x16 tire and tube to front wheel and encountered something that puzzels me. As I inflated the tube after mounting, the valve pulled out of my hand back into the wheel. The tube and tire were bought supposedly as a matched set. I thought that somehow I must have had the tube in backwords with valve facing away from rim hole so I took it off and remounted on correctly, although I think it was ok the first time. (The tube looked exactly like the one removed). It did the same thing but I used an extension so that I could hang onto it. I inflated and deflated a couple of time to get everytning strait inside. Although it pulled hard I got it done and installed the wheel. After about four days the tire went flat and sucked the valve back into the wheel. What am I missing?
 
Possibly a pinched tube that was difficult to see. When inflated the stretched rubber then failed. Baby talcum, and pre infleting the tube so it just holds a donut shape can help. Jim
 
being no expert,,,remove tube and completely deflate it,lay down on a flat surface and see which way the stem is pointing,,,my guess would be is the stem is in the wrong position...
 
Thanks for your responses. Actually I did use baby powder and the second time tube had a little air in in because I inflated it to search for damage after the first pass. I think that the flat will show to be damage from a tire iron removing and remounting, but maybe from a pinch. I was very carefull to not pinch it and tried hard to keep the irons away from tube. Do you think that I should seat the tire on the side of the rim with the valve hole before inflating? It seems like the tube wants to center on the recess in the rim and that is a considerabl distance from the horizontal hole in the rim.
 
you pinched the tube done it many times break it down again patch it and leave it off the tractor for a day and see if it goes flat its more fun when you pinch one of the rear tubes when i weigh 130lbs its hard for me to counter balance it
 
For sure! But I needed to take them off clean up, maybe repair, paint the rims and then remount. I have been doing one wheel at a time, therefor Doing it myself saves 2 trips per wheel. Also I thought that I was pretty good at it since it was part of my job 50 years ago, and I still do aircraft tires which are much easier. Guess all skills change with time.
 
I wish it only cost $6 here to get a tyre fitted here. More like $20 each on a good day. I do my own, front and rear on our tractors. When I fitted new front tyres on our Farmall H (5.50-16) I had the rims blasted and painted. To avoid damage I lay the rim on some heavy cloth and applied a abundant amount of rubber grease to the bead on the tyre. Easy to force the tyre on without any levers at all. Then fit the semi inflated tube and repeat the process for the other bead. The second bead is a little more trouble and may require two people to get enough push to force it on. If all is well the tube will behave. I have never pinched a tube by this method and it removes the possibility of damaging paint with a tyre lever. The rubber grease stops the bead rusting on to the rim.

Thanks for your reply. What do use for Rubber grease? I never heard of it. I have always used soapy water.
