Tires were getting too worn to be safe so I picked up some Cooper Discoverer STT 325/65-18.... They were a bear to get balanced but ride awww so smooth and nice.. There was a set of Nitto Trail Gapplers in the same size so I picked them up for a weight check. The Nittos were much heavier... No kidding these tires are lightweight for what they are and are close to the same weight as the 325/60-18 Terra Grapplers were. These did hurt the MPG a little but not much like other M/T's would've.
