Has surpassed my expectations for my Lexus SUV. As quiet and comfortable, smoother, better dry cornering and snow traction, though not as good in the wet cornering and about 3-4% worse in fuel consumption. Wear is much better - didn't see anything noticeable after 4000 miles. This is compared to the twice costly OEM Michelin MXV4 S8 I've replaced. To note: Tire size (245/55/18) is 10 mm wider than what is OEM on the RX which can explain the slightly increased fuel economy (increased drag and larger rolling diameter). However, it fits without rubbing in the wheel wells and the OEM tire pressure monitors continue to work without issue. Secondly, however, installation was painfully time consuming. Two of the four tires vibrated tremendously at all speeds and was fixed after two balancing attempts and lots of weight(3.5 and 4.5 ounces each wheel). I've also found a handful of complaints about balancing issues with these specific Spec tires on the net. Overall, no regrets though, I would buy a set of four again in a heart beat as the cost is significantly less than the next brand.
