I searched, but couldn't find anything that addressed this specific question. What exactly is the limiting factor to carrying a stock full size spare in the rear door? Tire diameter, tire width, or weight? Since Tom4Bren has a fullsize on his door, weight doesn't seem to be the problem, and I think there is enough room diameter wise to fit a stock tire in the door.

My thought is to get a "plain-o" steel wheel and mount a 245/70-16 in place of the donut, but I think the cover won't fit back on since the 245 is about 3" wider than the spare. Am I missing something?

Thanks!
