I found some wheels but I am not sure what is a good price. Also, I don't remember 15" Fuchs larger than 9" wide. I am wondering if the 10" maybe incorrect.

I would do a search on Pelican.

I remember seeing a chart of all the Fuchs with part numbers ans specs.

Edit.

This shows 11 x 15 but not 10 x 15.

likely they have been welded.. but still worth a look!
