I've never really been a fan of the asymmetrical tread designs, so was a bit nervous about getting these tires. I have tried many tires on my Mercedes R350 and these Firestones are at least as good as the Michelin Latitude Tour HP and better than the Continental 4X4 Contact. The ride they give is very solid but smooth. Handling is excellent, given the large size of the car. Best of all, these Firestones are FAR less expensive than Michelins or Conitnentals. If you have a luxury crossover SUV don't hesitate to try these tires.
My car eats tires in 30,000 miles (been through Conti, Michelin and Pirellis). I'll report back about how these wear over time.
