Trying to figure out buying a spare inner tube. I have a spare for the front tires but need one for the back tires. First thing I get asked is what size tire do I have on the back of my '24.
I am drawing a blank now, I seem to remember seeing 450 on the tire but I am told that should not be on the back wheels of a 24.
when it comes to inner tubes, does it really matter?
You may have 450-21" demountables. This is the same size tire and tube as the '26-'27 wire wheels and the '28-'29 Model A.
You'll have an easy time finding tires and tubes.
Your 24 touring as pictured on your profile has 30 x 3-1/2 tires.
They are split rim demountables.
Alan - I have 23" split-rim demountable rims.
I recently got new tires all around. I went from 30 x 3.5 tires from Coker because it was 5-yr old stock that they are phasing out and went with the "4.40-23/31x4" Lucas tires. They still take a 30x3.5 tube. Maytag at Lucas told me a range of tire sizes that take the 30x3.5 tube. Maybe you could email Maytag with your wheel/tire and he can tell you.
The 30x3.5 tube with rubber stem is TR-135 which is the standard model # and not a unique Lucas # .
you say you're buying it for a spare, i hope you know not to store it folded up in the package it comes in. folded, it will crack at the folds in only a few months. put a small amount of air inside, and store in an old tire
My experience with tubes is significantly different.
In Sept of 2013 I bought 4 new tires and tubes for my 1919 from Langs.
It was too cold to mount them that year and I didn't have time in 2014 or 2015 so the tires stayed on the shelf and tubes remained folded up in a box.
This weekend I finally have time and the sun is available to heat the tires, so I am mounting the tires
I had heard rumors that leaving the tubes folded for a long time could be a problem so my backup plan was to use the old tubes.
All 4 tubes are perfect.
My experience is that leaving tubes folded is not a problem.
