They're 255/50 (from an X5 and I can pick them up fpr $600 which certainly got my attention!

I know they're bigger than the stock 245/45's I have now but that doesn't bother me as long as they'll fit. I'll be moving to the Durango,CO area later this year and our cabin is about 20 miles away from the nearest paved road...

Any input greatly appreciated!

If your wheels are 18 inches with 245/45 your overall diameter is 677.7mm, with 255/50 overall diameter is 712.2mm, which is 35mm bigger or 1 1/2 inch roughly. I'm going to say that they will rub on full lock.
They'll rub. I ran X5 size on my X4 for a little while and they rubbed on full lock and past about 70-80% in reverse. Even after trimming the wheel liner back a bit, it was very annoying and I got rid of them.
