When I went to replace my tires I tried to get continental terrain contact a/t's as consumer reports rated then number one in their testing and also noted them to be fairly quiet. The tire place I used in florida brought a set in from the warehouse, but they were already two years old out of 4 spec'd by continuing and the tire company didn't want to reduce their price. So I put on the michelin defender ltx m/s tires on. Super quiet, but I find them to be a little less stable in steering than the all Terran tires I removed.
