Thanks Bob,

I am going back to the OEM size 155/80/13 tire since it seems to have the least RR due to contact patch size comparison. I will save about 1" on tread width which should reduce my RR a bit and seem to have a stiffer compound for the Kumho Solus K21. You can find some of the factors in me deciding on a tire in my Sig **Choosing a Tire**
