    The best way to test this is to take the axle out of the wheel and insert it into the receiver until it snaps in. Then measure the amount of axle showing and compare that to the distance from the outside of the outer bearing to the outside of the inner bearing on the wheel. If you come out with 2 7/8" on the first measurement, and 2 3/4" on the second, you know that you need to move the nut out 1/8". If you don't have that much adjustment left, you will need to get longer axles.

    You are correct sir!

    The Spox Hub is 2.5" inches and the Tilite flange is 2.0 inches in width, which is 1/2 inch difference.

    Explain the math on this? Why would a 1/2 inch width difference require a longer axle? I'm a computer guy, not a mechanical engineer. Educate me please!

    ...and thank you!

    Excellent diagram that details axle lengths

    I found the following diagram on the Quickie site that details axle information

    So in my case I have a Quick Release TI, with an axle width = 5.25"

    The Spinergy Wheel Quick release axle width = 4.5"

    So I believe that my situation is the Spinergy axles are too short.

    If I switched wheels and the hub was 0.5" longer, I wouldn't have enough adjustment in the nut because if I backed the nut out 0.5", the nut would fall out.

    You lost me, are you using the same axle on both wheels or do you have separate axles for each set of wheels?

    I solved the mystery!

    I just took the axles that came with the Spox spinergy tires out and replaced them with a flange axle that I had from a set of Sun Rims that I have on my tennis chair.

    With a small amount of nut adjustment I was able to fit them onto my TiLite.

    I appreciate the education and guidance. If I can return the favor with a computer or network related issue, please hit me up.

    I was going to suggest just that.

    You know I should always look for the easiest vs keeping the proper wheel/axle combination.

    On the topic of sharing, I purchased a "FreeWheel" at the NY/NJ Abilities Expo. Here's a picture of it:



    It allows me to get around the yard much easier. I goes on and comes off in under five seconds. It was a great investment for under $500
