Infinity really botched this one as they have this 40k vehicle riding like a wheel barrow. The car allows you to feel every bump in the road, and their low profile run flat tires no doubt contribute to this. They average $250 a pop and don't last long at all, but perhaps it's the AWD factor. If you aren't an advanced driver, the AWD can cause you to wreck on uneven pavement when accelerating quickly. I was going to buy taller tires but it would throw the cats calculation off. It would have been nice for the car to have room for a spare, too.
