My 2006 Sport V-8 came with Dunlop AT 20 Grandtrex tires. Tire Rack has them ranked about 62 out of 65 all season tires. I drive in CO mtns. year round and will need to change them before winter. Revos are well thought of but does anyone have experience with Cooper ATRs? Have heard good things about them in other forums and I have a set on my wife's 04 Limited. Only used them on highway so far towing a 2 place ATV trailer and they are quiet. Have heard they are good off road and in snow. It was a new design last year.
