I'm in the process of converting the tubes in my round felloe wheels to original metal stems. I just removed an old Firestone USA tire and tube from a spare wheel I have which took me all of 15 minutes. Here is the question: Why don't they sell tubes anymore with the correct size rubber valve stem? I've approached Coker, Universal, and Lucas about this problem, and although sympathetic, I've never gotten a straight answer. Here is the number from an old Wards tube I saved, and does fit. The Coker tube I removed from this tire, which is quite old also has the same size valve stem. It says Schrader 35 which at the base measures .540". The new stems they are currently using measure .600".
I would guess lowest bidder and i'm sure there made to a price instead of a quality? Bud in Wheeler,Mi.
I'd just like to have some decent replacement rubber stems and for some reason that stem isn't even available as a "patch" anymore. The trade name of the proper size rubber stem is TR135. These used to be available from the ag equipment dealers but the last time I saw them was ten or more years ago. Can't even get them on the net...
Coker advertises that all their 30 X 3 1/2 tubes have that stem Adam. Click here:

Had a friend give me a sack full of those rubber replacement stems.They have to be vulcanized on,so I took one to a truck shop.Cost me $20! You might as well by a new tube. I wish the tube people would wake up.
Royce, You are correct, some new tubes ARE advertised as having a TR135 stems, however, what I've been looking for is a TR135 "replacement rubber stem". It is a TR135 stem on a 2" self vulcanizing "patch".
I never thought of using a rubber stem much less replacing one. Why not just use old metal stems?
The point is why not do it correctly? I'm sick of these reproduction parts that don't work!
