Any reasons to choose one over the other:  Nexen SV820 or Hankook RA08? Nexen is a little less expensive, but not dramatically so.   BTW, both are available at WalMart, if ordered online.  Only Nexen if you go to the store.  Hankook but not Nexen is available at Discount Tire.  I do prefer to do business with Discount over WalMart.   Thanks, mcneely
