Yes they are 245/75/16 MTR's
The skid in those pics is just 2 signs that are setting there for a visual haha. I actually went down to the local metal shop and had them cut me out a piece of diamond plate. I think I am going to either put JEEP or RENEGADE across the plate and see how it all turns out. I'll get pics up someday with it all finished.
I used a utility knife to cut mine I just made a nice straight light cut then kept going over it again and again to get a nice clean cut. Only took about 20 mins and I didn't have to sand anything at all.
