Have a '99 RX300. In need of tires NOW, mostly city driving. Are Yokohama Geolander H/T - S G051 going to get better gas mileage than the duelers ( 17 mpg avg) I have on now?? Better ride (I feel like I'm in a pickup). Duelers are great for not hydroplaning and great in snow, but the ride and noise sucks. Is this a good option or is there something better? In a money crunch, also. Yokos are on sale thru today BOGO. Opinions, please?? Thanks!!
