I'd definately go with the 20.8's and the big floater rear tires. Have you ever ran a 12R head on a 2388IJ I've heard nightmares about it because of all the crop going into that tiny feederhouse, but that's all I've heard. From the little I know about the 12R ready machine, it's just some standard features that are options on the other combine, plus some weights, so unless you're set on it, you might want to stick with an 8R head.
