I've got a 2004 TR Sport 2WD and it's time to replace the tires. Done a lot of reading and still wondering best route to go. I'm probably 95% on road around Atlanta. I'm still wheeling around on the OE GrandTreks. I've been looking at a number of tires including the Revo (2), Scorpion ATR, Open Country and LTX A/T2. I'm concerned about the loss of gas mileage and increase in noise. Because the Dunlop's are considered highway all season I'm having a hard time comparing. I realize that if I go with an AT they won't be super quiet or fuel efficient, but does anyone know how they may compare with the OE Dunlops in those areas?
