chuckem, We got back yesterday. It's good to be back. Harvest was real good, in fact the best in the past seven years. The tires I would like to get rid of are 525R1257. If that size seems odd, I think it's metric. It replaces 20.8R42 I would love to put them on one of my 2388s for the fall harvest but I can't because I still run a six row corn head because most of the corn I cut is planted with a six row planter. K.A.
