Inner tubes and wheel questions

[CubbyRI]

sorry for another dumb question, but I dont know exactly which inner tubes for my 123

The rears are 23x8.50x12 and the stem comes out sideways in the inner step facing out.

The front are 16x6.50x8 has the stem same deal.


They say "Straight valve stem" is that the stem style what these wheels will call for?
I did find this cool list of stem types:

Tubes seem to have gotten expensive like 20 per...

Also, any advice on mounting these? I removed one old tire and ended up having to cut it off with a sawzall and even that was a fight! Whats the trick to putting tires with tubes on without wrecking everything?

Thanks!

I just installed tires with tubes for the first time. Used large 12" screwdrivers, soapy water and another set of hands. The rim needs to be clean and without rough weld splatter or rust spots that may puncture the tube.

I placed flat on the floor with another person holding the rim. Slop the rim and tire bead well with soapy water. Start the bead and push into the depressed area of the interior of the rim. Tire bead needs a place to go. First side bead went on by hand for me. Then carefully place tube in tire wiggling stem into the hole. Assure the tube is smooth, evenly within the tire. Place washer on stem and replace valve cap. Washer needs to be retained by valve cap. The purpose is to prevent loosing the stem into the rim while installing the second bead.

Second side is harder and requires leverage with the screwdrivers. Start at the stem, lots soapy water. By hand push tire on rim and workaround. Second person holds tire bead in wheel recess. Carefully pry the tire edges onto the rim.

Remove cap, washer, valve stem to inflate. Hold stem with pliers as air is added. I go slow allowing tube to conform to inner tire while squeezing tire.

Actually easier than I imagined. YouTube has many examples.

It works much better if one uses actual "tire spoons" or tire irons.
Most times "screwdrivers" screw it up causing tube punctures, especially for novices.
Google "tire spoons" usually comes in a set of 2 or 3.
I made my own, near 60 years ago and still use them.

George is absolutely right! tire spoons are like 5 dollars at harbor freight. well worth the cost and you need two. you cannot use too much lube. I prefer tire lube which is also very inexpensive but slightly diluted dish soap works . lastly since it is winter for most of us now - do your self a favor and put the tires inside the house for 24 hours - so they are warm and pliable.

Most steel LT/GT rims have a mount/dismount side - typically it is the valve side of the rim because they were made to be mounted on a machine and inflated in one swift operation - this is the case when one edge of the rim is rolled over further than the other edge, if the edges are rolled the same then it does not matter
fronts I find are easiest to mount with a large bolt/washers/nut through the axle tube tightly then held in a vise by the bolt.
rears I find are easiest to mount on the ground on a rug or doormat for traction on the first bead (if you are installing a tube after the first bead is mounted is the time to place your tube in the tire) then stand on the tire to force the bead into the drop center of the rim. use your tire spoons to get the second bead over the rim

wire brush/media blast and smooth rough spots fill holes and paint the inside and outside of your rim before mounting the tires!

all great advice. and never would have noticed a mounting side of the rim

I don't know the proper name for this or if you can even get one nowadays, but it is invaluable to me.
This came from a small mom & pop tire shop where my dad worked for a few years back in the 60's.
After the tube is in the tire, you pass the cap through the stem hole and attach to the valve. Finish the mounting, then you can pull the valve through the hole and remove.
Probably easy to make if you can't find.

thats awesome ironman. but I did see that using those can cause the users eyes to bulge excessively. thats prob just bs tho.

Thanks guys.

Now I really still need to know what stem type works with these wheels based on where the stem hole is..

Since they came originally tubeless (IIRC) there is no spec

You can use the top one pictured in the link that you posted (tr13)

thanks. so even though the tube seems to have the stem in the center, it can stick of sideways like that? ok...

also, now I am wodering if I should even use tubes or just bead sealer!
