Crager Rim question to fit bigger tires

Bought my Jeep with these rims already on them

http://www.performanceplustire.com/...manufacturerID/132/productID_/3434#prodAnchor

looking at used MTR's with a size of 32x11.5x15. My current tires are 30x9.5x15. The rim from lip to lip measures 9.5" wide...

Does anyone know if these tires would/should fit my current rims? Looks like then narrowest rim they make in this size is 15x7

here are some bad pics, in case that would help, lol

they'll fit.

Your rims should be stamped with the size somewhere on the back side of your wheel, or possibly near the center on the outboard side of the wheel. Those look like 15X7" & If they are, an 11.50 is the very widest tire you should use on it. If they are 15X8" then up to 12.50, no problem.
