We put the SDX press wheels on our 1890 this past winter.  As of today they have just over 3000 acres on them and we have replaced 16 of 48.  That seems pretty poor to me and I am wondering if this is unique to us, or if others have had the same problem.  We are trying to decide if we need to go let the local hot headed CNH parts manager yell at us or just cut our loss.
