Thread: Help with correct tube size

  1. #1

    Help with correct tube size

    Hi!

    I am new here and a t-7 complete para.
    I have standard 24 x 1 3/8 black mag wheels.
    I bought two pairs of 24 x 1 3/8 wheelchair tubes online from a reputable dealer.
    After I installed,it went flat.
    Out of desperation,I checked the tube and the other boxed tube under water for problems.
    I found out the valves were defective and tiny air bubbles were coming out of the valve under water.
    So,I bought 2 new tubes at Kmart.
    They were 24 x 1 3/8 tubes.
    I installed them but after about 20 minutes,the tire blew of the rim.
    So,I took it to a bike shop.
    I explained to him that they are 540 rims.
    I know that bike rims are 507.
    So,I knew I needed 540 tubes.
    He told me the rim size didn't matter as long as its 24 diameter rim.
    My home health aide picked up my newly installed tube today from the bike shop.
    After about 30 minutes,it blew off when I was wheeling outside.
    The tire blew off of the rim like before.

    Any help would be appreciated.
    Do you think its my weight that is causing it?
    I have a Quickie 2 wheelchair and I weigh about 200 pounds and I carry a 3 liter water bottle with me on the back of my wheelchair.
    My wheelchair came with solid wheels,but I only use them in an emergency because the wheelchair is too heavy to push with them outside.
    So I bought a second pair of black mag wheels years ago.
    It only cost me around 138.00 for them.
    Do you think the Quickie wheelchair is only meant for solid wheels.
    Sorry for my long post.
    I don't know how much information to give,thanks!

    sounds to me you need to find a reputable wheelchair shop.
    I use thorne resistant inter tubes.

    I use these

    check your tires for thorns ect sticking threw. the outside and the inside of the tire.

    I check the the inside of the tire but I do not feel anything.
    The numbers on the side of my tire say 24 x 1 3/8 37-540.
    Will the number 24 x 1 tube work in a 24 x 1 3/8 tire?
    My tires are also worn down in the middle a lot and are pretty easy to take off with my tire levers.
    Do you think the tires have become so supple that the tube pressure is blowing my tire off the rim.
    Its just that I hear a sound like a balloon stretch before it pops and the tire is about 3/4 off the rim when it blows.
    Thanks for responding.
    My first time posting anything to an online forum before,lol.

    Seems like something in the rim is causing them to blow. Are you putting rim strips between the tube and the wheel rim?

    The mag wheels did not come with any rim strip.
    Should I put some on?

    You can buy them with the tubes for a buck or so. I'd try it.

    It sounds like you answered your own question. I'm guessing your tires are so worn that the tube is just herniating between the rim and sidewall and blowing out.

    Of course, there is the problem, you can just give a few turns to the rim with some insulating tape, and after make a hole for the valve.

    As you can see in the pic, is just insulating tape 2 or 3 layers depending quality of tape.

    On Monday when my SSD check comes in I will buy the rim strip and tires and tubes.
    I will let you all know how it works out.
