I just researched as I wasn't absolutely sure which wheels were put on my machine. I did get them from my dealer at a quilt show a couple of years ago but they weren't put on the machine until last year.
Googling "EZRider quilt machine wheels" I only came across references to "Edgerider" wheels. The ones pictured are white my new wheels are black but I know they are not like the original Gammill wheels. These ride higher and are much smoother riding.
I just googled "EZGlider" wheels. Here's a link describing them:

These are black but I don't think mine have the green in the middle of the wheel but otherwise they look the same.
Mine cost a little less than the price shown on the link.
So, I'm thinking I have the EZ-Glide wheels. They are working fine and ride much smoother than the original wheels.
