Thanks for all the quick responses on my tire question.  Made up my mind and
placed the order this morning for the Nokian's.  I decided to bite the
bullet in order to get a true all season tire.  Although the Hankook RA08
appears to be as good (or better) than the Agilis I've been running for five
years the RA08s didn't rate any better 'in the wet' than the Agilis and I
found that the Agilis, although a great highway tire and very good in the
rain on pavement were woefully lacking in just wet grass and a little mud.
Therefore going to a true all season tire with a great reputation.
So thanks again for the quick responses...
