Hey Nick,
This is how I fit the wedico tires to my meir wheels.
First I ground down the lips on the inside with my bench grinder(be careful not
to nick the outer rim).

In this pic,I cut off the long portion of the hub so I could use my hub covers.
Then I wet the tire to help slide it on (this helps when you are doing a bunch of
tires).
When you get the tire on the wheel it will be lop-sided.
You will need to work the tire around the wheel with your fingers.
Then you are done!
