I am experimenting with higher tire pressure, and not sure of the results due to temperature changes. But I feel like I may have lost some cornering ability with more tire pressure. The Michelin Green X are pretty good (I also have them on my Ford Escape work vehicle), but don't have quite the sidewall stiffness I would prefer for fast cornering in the curvy roads I drive on.
I did a little research on TireRack and really want to try these:
DEFENDER LTX M/S
They get great rating for everything, and are still in the Eco class. I like the visibly stiffer edge, and also like the side rain evacuation slots. I know that design to work well against hydroplaning. I also had good traction in snow with that type of design. I'm really tempted to get a set and compare, but what do I do with the original tires? No doubt, this will be my "next set".
