These are slightly larger in overal diameter, but has anyone tried the Goodyear Marathon Radial in 205/75-14?  It is available with load rating of C (1760 lb) and has a max PSI of 50.  Here is a link:

Has anyone tried this?  I wouldn't mind the very slightly larger overall diameter to get a tiny rpm drop on the highway.
